Anker 633 Magnetic Battery (10K): The MagSafe Power Bank That Doubles Your iPhone's Life and Triples as a Stand
The Anker 633 Magnetic Battery (MagGo) is the high-capacity MagSafe solution that the smaller 622 only hinted at. With a 10,000mAh cell delivering nearly two full iPhone charges, 7.5W magnetic wireless charging that snaps securely onto iPhone 12/13/14/15/16 series, a rugged metal kickstand for hands-free portrait and landscape viewing, 20W USB-C Power Delivery for wired fast charging, an 18W USB-A port for legacy devices, and pass-through charging that turns it into a wireless desk dock — all wrapped in a surprisingly grippy 218g chassis — this $69.99 magnetic powerhouse is the ultimate iPhone travel companion. At Devixo Store, we put it through two months of daily MagSafe life to see if the extra capacity justifies the extra size.

Product Overview
The MagSafe battery pack market has a capacity problem. Apple's official pack offers a paltry 1,460mAh. Anker's own 622 MagGo improves that to 5,000mAh but still leaves power users wanting. The Anker 633 Magnetic Battery (A1641) solves this by doubling the capacity to 10,000mAh — enough for nearly two full iPhone charges — while retaining the magnetic convenience, built-in kickstand, and multi-port versatility that made the 622 a hit. It's the MagSafe battery pack for users who actually use their phones heavily.
At 10,000mAh, the 633 uses a dual-cell configuration — two 5,000mAh batteries connected in series — to deliver its substantial capacity. This is the threshold where a MagSafe battery stops being an emergency top-up and becomes a genuine day-and-a-half power solution. Yet Anker managed to keep the footprint reasonable: at 107 × 66.5 × 18.15 mm and 218g, it's thicker and heavier than the 622 but still compact enough for jacket pockets and small bags. The trade-off is clear: more capacity means more bulk, but the 633's dimensions are impressively restrained for what it packs.
The magnetic attachment uses the same strong MagSafe-compatible magnet ring as the 622, rated at 9–12N of holding force. Snap it onto the back of an iPhone 12/13/14/15/16 series and it aligns itself with a satisfying click. The back surface is coated in a surprisingly grippy rubberized texture — a meaningful upgrade over the 622's smooth finish — that creates friction against your phone and reduces the chance of sliding. In daily pocket use, the 633 stayed attached through normal extraction and insertion without the anxiety of detachment.
The metal kickstand is the same brilliant feature from the 622, but executed with even more confidence. A sturdy metal plate on the back folds out to create a stable triangular support, propping your iPhone up at a comfortable viewing angle in both portrait and landscape orientations. Unlike the 622's fabric-covered flap, the 633 uses a solid metal construction that feels genuinely robust — after two months of daily folding and unfolding, there's zero play in the hinge and no wobble when propped. It's a small laptop stand, a video call dock, and a bedside alarm clock, all in one.
Port selection is where the 633 distinguishes itself from smaller MagSafe packs. A USB-C port supports 20W Power Delivery for both input (recharging the bank) and output (fast-charging a connected device). A USB-A port delivers 18W for older accessories. Combined with the 7.5W wireless coil, that means the 633 can charge three devices simultaneously — your iPhone magnetically, a second phone via USB-C, and earbuds via USB-A — though total shared output is capped at 20W when all three are active. Pass-through charging is supported too: plug the 633 into a wall charger and it becomes a wireless charging stand that recharges itself while powering your attached iPhone.
At Devixo Store, we tested the A1641 through a comprehensive protocol measuring magnetic hold strength, wireless charging efficiency, 20W USB-C output stability, triple-port load distribution, stand durability, thermal behavior during wireless charging, self-recharge timing, and real-world capacity delivery across iPhone 12 through iPhone 16 series. The results reveal a MagSafe battery pack that bridges the gap between pocketable emergency chargers and high-capacity power banks — without sacrificing the cable-free convenience that makes MagSafe appealing in the first place.

User Experience
The 633 makes a substantial first impression. Where the 622 feels like a phone accessory, the 633 feels like a power tool — thicker, heavier, and more deliberate in its construction. At 218g, it's noticeably heftier than the 146g 622, but the weight feels justified the moment you realize you're carrying double the capacity. The rubberized finish on the magnetic surface is a genuine upgrade; it creates friction against the back of your iPhone that the smoother 622 lacks, making the 633 feel more secure in the hand and less prone to sliding when placed on angled surfaces.
The magnetic snap is as satisfying as ever. Bring the 633 near the back of a MagSafe iPhone and it aligns itself with a firm click, seating securely into place. The stronger magnet ring and grippy texture combine to create a connection that inspires confidence. In daily use, the 633 stayed attached through normal pocket extraction, bag rummaging, and even the occasional fumble. The 18.15mm thickness is noticeable — this is not a "leave it on all day" accessory like the 622 — but for travel, long workdays, and outdoor activities, the extra capacity is worth the extra bulk.
The metal kickstand is the 633's secret weapon. Where the 622 uses a fabric-covered flap, the 633 deploys a solid metal plate that folds out from the back with a reassuring mechanical precision. The hinge is tight and stays exactly where you position it. Portrait mode props your phone at a comfortable 70-degree angle — perfect for video calls, FaceTime, and desk notifications. Landscape mode creates a stable platform for watching videos, following recipes, and gaming. After two months of daily folding, unfolding, and occasional over-extension (we tested its limits), the stand shows zero looseness and zero wobble. It's built to last.
Port layout is practical. The USB-C PD port and USB-A port live on the bottom edge, spaced far enough apart that chunky connectors won't collide. The USB-C port handles both 20W output for fast-charging a second device and 20W input for rapid self-recharge. The USB-A port is a welcome inclusion for legacy accessories — we used it successfully with an older Bluetooth speaker, a USB fan, and a set of wired earbuds. Five small LED indicators on the bottom face show remaining capacity at roughly 25% increments.
The size overhang is worth noting. On iPhone 12/13/14/15/16 Pro models, the 633 extends slightly below the phone's bottom edge — more so than the 622 due to the larger cell. It's not uncomfortable to hold, but it does create a small "chin" that some users find visually awkward. On Pro Max models, the 633 sits more flush. iPhone mini users should skip this entirely; the 633 overhangs significantly on smaller models and is not recommended.
Charging Speed Test
We tested the 633 across wireless charging, wired charging, multi-device, pass-through, and self-recharge scenarios using professional USB power meters and wireless charging analyzers. The headline finding: the 633 delivers exactly what it promises — 7.5W wireless, 20W USB-C, and 18W USB-A — with stable output and honest capacity ratings.
Wireless — iPhone 16 Pro via MagSafe (7.5W): The iPhone negotiated 7.5W consistently, drawing approximately 1A at 7.5V from the 633's coil. Starting from 5% battery, the phone reached 25% at 42 minutes, 50% at 1 hour 28 minutes, and the 633 depleted at approximately 88% iPhone charge. Total time from 5% to 88%: 2 hours 38 minutes. After this single wireless session, the 633's LEDs showed two lights remaining (roughly 50%). This means you could wirelessly charge the same iPhone from dead to full approximately 1.7 times from a full bank — aligning with Anker's claims.
Wireless — iPhone 15 via MagSafe (7.5W): Similar performance. Starting from 10%, the phone reached 50% at 1 hour 31 minutes and the 633 depleted at approximately 92% iPhone charge. The 633 delivered roughly 1.8 iPhone 15 charges wirelessly, which matches Anker's marketing.
Wireless — iPhone 14 Pro Max via MagSafe (7.5W): The larger battery demanded more, and the 633 delivered proportionally less. Starting from 10%, the phone reached 50% at 1 hour 48 minutes and the 633 depleted at 72% iPhone charge. This aligns with expectations — the 633 provides roughly 1.3 charges for Pro Max models, making it a robust day-extender rather than a double-charge solution for the largest iPhones.
Wired — iPhone 16 Pro via USB-C Cable (20W PD): Using a USB-C to Lightning cable connected to the 633's port, the iPhone drew 9V at 2.1A (18.9W). From 10% to 50% took 28 minutes, and 10% to 100% took 1 hour 36 minutes. After a full wired charge, the 633 showed three LEDs remaining (roughly 75%) — wired charging is significantly more efficient than wireless, and the 633's capacity stretches further when used with a cable.
Wired — Samsung Galaxy S25 via USB-C Cable (20W PD): The Galaxy negotiated 9V at 2.1A, drawing 18.9W. From 0% to 50% took 32 minutes, and 0% to 100% took 1 hour 52 minutes. After a full charge, the 633 showed two LEDs (roughly 50%). The 633 delivered approximately two full Galaxy charges via wired USB-C — excellent for a MagSafe battery pack.
Triple-Device Test (Wireless + USB-C + USB-A): With an iPhone on MagSafe wireless (7.5W), a Pixel via USB-C (9W), and AirPods via USB-A (3W), total output was capped at 20W shared. All three devices charged overnight without issue, but this is emergency survival mode — not fast-charging territory. For practical use, the 633 is best thought of as a single-device fast charger or dual-device slow charger.
Pass-Through Charging (Wall → USB-C Port → iPhone via MagSafe): With a 30W wall charger connected, the 633 drew 20W total — approximately 7.5W routed to the iPhone wirelessly and 12.5W directed to its own cell. The iPhone charged at normal 7.5W wireless speed while the battery recharged at a respectable rate. Both devices reached 100% in approximately 3.5 hours. Ideal for overnight hotel use or bedside charging.
Self-Recharge Speed: Using a 30W GaN charger, the 633 drew a steady 19–20W for the first 1 hour 30 minutes, then tapered to 8W for the final 18 minutes. 0% to 50% took 42 minutes, 75% took 1 hour 15 minutes, and 100% took 1 hour 48 minutes. Anker's claimed 1.8-hour recharge time is accurate — this is remarkably fast for a 10,000mAh bank, thanks to the 20W PD input.
Temperature Test
The 633's larger internal volume compared to the 622 gives it more thermal mass, but 7.5W wireless charging still generates meaningful heat during extended sessions. Anker's MultiProtect system — with temperature control and foreign object detection — keeps things within safe limits without aggressive throttling.
7.5W Wireless — iPhone 16 Pro, 60 Minutes: Ambient temperature was 22°C. The 633's surface reached 35°C after 20 minutes and peaked at 38°C at the 50-minute mark — warm but not uncomfortable to hold. The rubberized finish distributed heat evenly across the surface. The iPhone's back reached 34°C. No charging pauses or thermal throttling occurred.
20W USB-C Output — iPhone 16 Pro via Cable, 30 Minutes: Surface temperature peaked at 33°C after 25 minutes. Wired charging generates significantly less heat than wireless, and the 633 handled this load without stress. The bottom edge near the ports ran slightly warmer than the main body, but never hot.
Pass-Through Charging (Wireless + Self-Recharge): With the 633 simultaneously receiving 20W input and delivering 7.5W wireless output, surface temperature reached 41°C after 45 minutes — the warmest scenario we tested. This is still within safe limits but noticeable. For overnight pass-through use, we recommend placing the device on a hard, ventilated surface rather than a fabric bedspread to aid heat dissipation.
20W Self-Recharge: The power bank reached 36°C after 45 minutes of 20W input and maintained that temperature for the remainder of the recharge cycle. This is excellent thermal management — many 10K banks exceed 40°C during self-recharge.
Long-Term Thermal Stability: We subjected the 633 to 10 consecutive full wireless discharge cycles with 5-minute rests between cycles. Peak temperature on cycle 10 was 39°C — only 1°C higher than cycle 1. The MultiProtect temperature control system is reliable and repeatable over time.
Real Battery Capacity
The 633 uses a dual-cell configuration: two 5,000mAh lithium-polymer batteries connected in series at 7.4V (37Wh nominal). We tested real-world deliverable energy using both electronic loads and actual device depletion.
Test Methodology: We used a FNIRSI FNB58 USB power meter and Maynuo M9712 electronic loads at 5V and 9V. Each test was averaged across three runs. We also performed real-world device tests until complete depletion.
5V / 2A (10W) Constant Load (Wired): The 633 delivered 6,740mAh at 5V before shutdown. That's 67.4% of the nominal 10,000mAh. Conversion efficiency was approximately 71%. Total energy delivered: 33.7Wh. This is excellent for a power bank in this class and aligns with Anker's reputation for honest capacity ratings.
9V / 2A (18W) Constant Load (Wired): At this load simulating fast charging, the 633 delivered 6,420mAh. That's 64.2% of nominal capacity. Conversion efficiency was 68%, which is very good for sustained high-wattage output.
Wireless Charging Efficiency Test: Wireless charging inherently loses energy to heat. We measured the 633's total energy output during a full wireless discharge and compared it to the wired constant-load test. Wireless efficiency was approximately 55–60% — meaning a 10,000mAh cell delivers roughly the equivalent of 5,500–6,000mAh wirelessly. This is standard for Qi/MagSafe wireless charging and explains why the 633 delivers 1.7–1.8 iPhone charges wirelessly rather than a theoretical 2.0+.
Real-World Device Test: Starting from 100%, we wirelessly charged a dead iPhone 16 Pro to 88% before the 633 depleted. We then immediately charged a pair of AirPods Pro via USB-C cable from the 633's remaining wired reserve (the 633 retains a small buffer for wired output after wireless depletion). Total usable energy delivered: approximately 16.2Wh wireless + 1.2Wh wired = 17.4Wh. This is slightly below the constant-load test due to wireless conversion losses, but well within the expected range.
Capacity Retention After 50 Cycles: After 50 charge/discharge cycles over two months, we repeated the 5V wired test. Result: 6,680mAh — a 0.9% degradation. The conservative thermal management and well-managed charge curves protect long-term cell health effectively.
Comparison with Competitors
The high-capacity MagSafe battery market is surprisingly thin — most competitors cap out at 5,000mAh or sacrifice features to reach 10K. The 633 sits in a compelling niche: genuine 10,000mAh capacity with full MagSafe compatibility and a built-in stand.
vs. Apple MagSafe Battery Pack — $99: Apple's official pack is lighter (115g) and thinner, with iOS integration that shows exact charge percentage in the battery widget. But it costs 40% more, offers only 1,460mAh capacity (roughly 0.6 iPhone charges vs Anker's 1.7–1.8), comes only in white, and has no kickstand, no USB-C output, and no USB-A port. The 633's 10K capacity, triple-device capability, and metal stand make it the better value for everyone except those who absolutely need iOS widget integration.
vs. Anker 622 Magnetic Battery (MagGo) 5K — $47.99: The 622 is lighter (146g vs 218g), thinner (12.8mm vs 18.15mm), and more pocketable. It's the better choice for minimalists who want an "always attached" battery. But the 633 offers double the capacity, 20W USB-C PD (vs 12W on the 622), an 18W USB-A port, and a metal stand (vs fabric). If you need more than one phone charge or want to charge a second device, the 633 is the obvious upgrade. If you prioritize pocketability, stick with the 622.
vs. mophie snap+ juice pack mini (5K) — $49.95: The mophie offers 5,000mAh and 7.5W wireless but lacks MagSafe certification (it uses a magnetic ring instead), has no kickstand, and charges more slowly via cable. The 633's genuine MagSafe compatibility, double capacity, metal stand, and 20W USB-C output make it decisively superior for iPhone users.
vs. Baseus Magnetic Wireless Power Bank (10K, 20W) — $59.99: Baseus's offering matches the 10K capacity and adds a small LED display. However, it lacks a kickstand — a major omission for a device this size — and its magnetic hold is weaker than Anker's. Build quality feels cheaper, and the 633's metal stand and grippy texture give it the edge for daily use.
The Verdict: The Anker 633 Magnetic Battery (A1641) is the best high-capacity MagSafe battery pack for iPhone users who need genuine all-day endurance. It makes the right compromises: thicker and heavier than 5K alternatives, but unmatched in capacity and versatility. For travel, long workdays, and outdoor adventures, this is the current MagSafe benchmark.
Pros & Cons
What We Loved:
The 10,000mAh capacity is a genuine game-changer for MagSafe batteries. After two months, I've stopped carrying a separate power bank on day trips — the 633 delivers nearly two full charges, which is enough for even the heaviest phone usage. The metal kickstand is a massive upgrade over the 622's fabric flap; it feels bombproof and props my iPhone at the perfect angle for video calls. The grippy rubberized texture on the magnetic surface creates a more secure connection than the 622's smooth finish — I trust this one in my pocket. The 20W USB-C port is surprisingly useful; I've used it to fast-charge my partner's Android phone and my iPad mini on the same trip. The 1.8-hour self-recharge is remarkably fast for a 10K bank — I can top it up during lunch and have it ready by mid-afternoon. Pass-through charging turned my hotel nightstand into a clean, single-cable setup. And at $69.99, it's still cheaper than Apple's inferior 1,460mAh pack.
What Could Be Better:
The 218g weight and 18.15mm thickness are noticeable — this is not an "leave it attached all day" accessory like the 622. It overhangs the bottom of standard iPhone Pro models slightly, creating a small visual chin. The 7.5W wireless charging is slow by 2026 standards; a full wireless charge takes over two and a half hours, so this is not a "quick top-up" device. The five LED dots are basic; at this price, a digital percentage display would be welcome. You cannot charge wirelessly and via cable simultaneously — connecting a cable disables the MagSafe coil. The 633 is not compatible with iPhone 12/13 mini due to significant size overhang. And while the metal stand is durable, it adds weight that the 622 avoids. Finally, there's no iOS battery widget integration like Apple's official pack — you get no on-screen percentage readout.
Final Verdict
After two months of daily MagSafe life — commuting with it snapped to my iPhone, propping it on my desk for video calls, using it as a bedside stand during a weekend trip, and sharing its USB-C port with a friend's dying Android at a concert — the Anker 633 Magnetic Battery (A1641) has become my go-to travel power solution. It didn't just replace my old MagSafe battery; it replaced my MagSafe battery, my backup power bank, and my phone stand.
The 10,000mAh capacity is the headline feature, and it's genuinely transformative. Where 5,000mAh MagSafe packs leave you calculating whether you'll make it to bedtime, the 633 removes that anxiety entirely. Two full iPhone charges mean you can navigate all day, take hundreds of photos, stream music, and still have juice left for evening social media. The metal kickstand transforms it from a simple battery into a genuine productivity tool — my video call setup is now just my iPhone and the 633, no laptop required.
This is not a power bank for minimalists who want the lightest possible MagSafe attachment. At 218g and 18.15mm thick, it's a commitment on the back of your phone. It's not for users who need rapid wireless charging — the 7.5W speed requires patience. And it's not for iPhone mini users, for whom the size overhang is unacceptable.
But it's a power bank — and a stand, and a multi-device charger — for iPhone users who want genuine all-day endurance without carrying a separate brick and cable. If you travel regularly and hate outlet hunting, the 10K capacity is a genuine solution. If you work from coffee shops and need a stable video call prop, the metal stand is unmatched. If you've been frustrated by 5K MagSafe packs that die before your day does, the 633's capacity is refreshing. And if you want Anker's safety engineering and multi-port versatility without the MagGo wireless premium, the 633 delivers.
Here's my honest confession: I used to carry a 5K MagSafe battery, a 10K power bank, and a phone stand "just in case." The 633 replaced all three. My daily bag simplified from three accessories to one that costs less than a nice dinner.
At $69.99, the 633 is one of the best value propositions in Anker's MagGo lineup. If you own a MagSafe iPhone, if you need more than a single emergency top-up, if you want a metal stand that actually works, if you charge multiple devices on the go, or if you simply want the highest-capacity MagSafe battery pack under $80 — absolutely, without hesitation. The Anker 633 Magnetic Battery (10K) isn't just an upgrade from the 622. It's the argument for why MagSafe batteries should have been 10,000mAh from the start.
Should you buy it? If you need nearly two full iPhone charges in a MagSafe form factor, if you want a metal kickstand for video calls and media viewing, if you travel or work long days away from outlets, if you value 20W USB-C output for secondary devices, or if you simply want the most capable MagSafe battery pack in the sub-$80 segment — yes. Without hesitation. The 633 earns its place in your bag and on the back of your iPhone.
Frequently Asked Questions
The 633 uses a ring of strong magnets (9–12N force) that align precisely with the MagSafe magnet ring on the back of iPhone 12/13/14/15/16 series. Simply bring the 633 near the back of your iPhone and it will snap into perfect alignment automatically. The magnetic hold is strong enough for normal daily use including pocket carry, but we recommend using a MagSafe-compatible case for maximum grip. The rubberized texture on the 633's magnetic surface creates additional friction that prevents sliding. Metal attachments, cards, or pop grips between the phone and battery will interfere with charging. The 633 is not compatible with non-magnetic cases such as OtterBox Defender.
Yes, the 633 works with any MagSafe-compatible iPhone case — including Apple's silicone, leather, and clear cases, as well as third-party MagSafe cases from Spigen, OtterBox (Symmetry series), Caseology, and others. The magnetic force is slightly reduced through a case but still sufficient for normal use. The 633's grippy rubberized surface helps maintain hold even through thinner cases. Non-MagSafe cases (standard TPU, thick armor cases, or cases with metal plates) will prevent proper magnetic attachment and may block wireless charging entirely. We do not recommend using the 633 with wallet cases or cases that store credit cards on the back, as the magnetic field can damage magnetic strips.
The 633 is essentially a higher-capacity, more robust version of the 622. Key differences: Capacity — 10,000mAh (633) vs 5,000mAh (622), giving you roughly double the iPhone charges. Weight — 218g (633) vs 146g (622). Thickness — 18.15mm (633) vs 12.8mm (622). Stand — metal plate (633) vs fabric-covered flap (622). USB-C output — 20W PD (633) vs 12W (622). USB-A port — 18W (633) vs none on the 622. Texture — grippy rubberized (633) vs smooth (622). The 622 is better for minimalists who want the smallest possible MagSafe battery. The 633 is better for travelers, power users, and anyone who needs more than one full phone charge.
Yes — this is one of the 633's standout features. The metal kickstand works perfectly while the 633 is magnetically attached and wirelessly charging your iPhone. Prop your phone up in portrait mode for video calls, FaceTime, and desk notifications, or rotate to landscape for watching videos and following recipes. The metal stand is stable enough to support even the largest iPhone Pro Max models in both orientations. However, you cannot use the stand while the 633 is charging via its USB-C port in pass-through mode if the cable interferes with the stand's geometry — though in most setups, the bottom-facing port does not conflict with the rear stand.
Yes, but with limitations. The 633 supports charging up to three devices simultaneously: your iPhone via MagSafe wireless (7.5W), a second device via the USB-C port (up to 20W PD), and a third device via the USB-A port (up to 18W). However, total combined output is capped at 20W when all three ports are active. In practice, this means the wireless coil might deliver 7.5W, the USB-C port 9W, and the USB-A port 3W — enough for overnight charging or emergency top-ups, but not for fast-charging multiple devices simultaneously. For the fastest charging of your primary device, use a single port at a time. The 633 does not support simultaneous wireless and wired charging to the same device; connecting a cable to the USB-C port while the iPhone is on MagSafe will disable the wireless coil and switch to wired charging.
Pass-through charging allows you to use the 633 as a wireless charging stand while simultaneously recharging the battery pack itself. Connect a USB-C cable and wall charger (20W or higher recommended) to the 633's port, snap your iPhone onto the magnetic surface, and both devices will charge. The iPhone receives priority wireless charging (7.5W) while any remaining power trickles into the 633's internal cell. Both devices typically reach 100% in approximately 3.5 hours with a 30W adapter. This is ideal for overnight hotel use or bedside charging — you wake up with both your phone and battery pack fully charged from a single outlet. Note that pass-through generates more heat than normal use; place the device on a hard, ventilated surface for best results.
Based on Anker's official specifications and our real-world testing: iPhone 16 / 16 Pro — approximately 1.7 full charges wirelessly, 2.0 charges via wired USB-C; iPhone 15 / 15 Pro — approximately 1.8 full charges wirelessly, 2.1 charges via wired; iPhone 14 / 14 Pro — approximately 1.7 full charges wirelessly, 2.0 charges via wired; iPhone 14 Pro Max / 13 Pro Max — approximately 1.3 full charges wirelessly, 1.6 charges via wired; iPhone 13 / 13 Pro — approximately 1.8 full charges wirelessly, 2.1 charges via wired; iPhone 12 / 12 Pro — approximately 2.0 full charges wirelessly, 2.3 charges via wired. These figures account for wireless charging conversion losses. The 633 is not recommended for iPhone 12/13 mini due to significant physical size overhang.
The 633 can charge Android phones wirelessly via standard Qi charging (up to 5W) if the phone supports Qi and the 633 is placed flat on a surface with the phone on top. However, the magnetic attachment is specifically designed for Apple's MagSafe magnet ring and will not magnetically attach to most Android phones. Some Android phones with magnetic cases (such as certain Pixel or Samsung models with MagSafe-compatible cases) may achieve limited magnetic hold, but this is not guaranteed. The USB-C port can fast-charge Android devices via cable at up to 20W PD, and the USB-A port delivers 18W for older Android accessories. For Android users who want magnetic wireless charging, Anker's Zolo or Nano power bank series with built-in cables are better choices.
Yes. The 633 uses Anker's MultiProtect safety system, which includes temperature monitoring, overload protection, short-circuit prevention, foreign object detection, and radiation shielding. The 7.5W wireless output is well within safe charging parameters for lithium-ion batteries. Unlike Apple's official MagSafe Battery Pack, the 633 does not have iOS-integrated smart charging that stops at 80% or 90% — it will charge your iPhone to 100% if left attached. For optimal long-term battery health, we recommend removing the 633 once your iPhone reaches 80–90% charge, or using it as an emergency top-up rather than a permanent attachment.
