Short description (approx. 150 chars) A 10,000mAh power bank with a built-in Apple Watch fast charger, a 30W USB-C cable and a fold-out stand, so one pack charges your watch and phone.

Long description

The Anker MagGo Power Bank for Apple Watch (10K, 35W) combines a 10,000mAh battery with an integrated Apple Watch charging puck. The watch charges on the magnetic pad at up to 5W, and the pack also powers a phone, tablet or laptop through a built-in USB-C cable that doubles as a carrying strap. An adjustable stand holds the watch upright for nightstand or desk use.

The USB-C output reaches 30W, enough for fast charging modern iPhones, iPads, Android phones, handheld consoles and light laptop top-ups. Total output is 35W, and when the watch and USB-C run together the combined output is 24W. A hidden LED display shows remaining charge and charging power.

Best for travelers, commuters and anyone who charges an Apple Watch and a phone on the go and wants to carry a single accessory. If you do not own an Apple Watch, compare Anker’s Qi2 MagGo power banks on Discompare instead.

    Q1. What is the Anker MagGo Power Bank For Apple Watch?

    It is a 10,000mAh (37Wh) power bank with a built-in Apple Watch fast charger and a built-in USB-C cable. The watch charges wirelessly on the magnetic pad, while the USB-C cable charges a phone, tablet, earbuds or other devices. Anker’s formal name is “MagGo Power Bank (10K, 35W, For Apple Watch)” and the model number is A1657.

    Q2. Who is it for?

    It suits anyone who charges an Apple Watch and a second device on the move: travelers, commuters, hikers, gym-goers and people who want one small accessory for a phone and a watch. If you do not own an Apple Watch, a standard MagGo Qi2 power bank is usually the better value.

    Q3. What is in the box?

    According to Anker: the power bank with its built-in USB-C cable, an adjustable stand for the Apple Watch, and documentation. No separate wall charger is included, so you need your own USB-C power adapter to recharge the pack.

    Q4. What colors does it come in?

    Anker lists Black Stone, Aurora White, Pink Aura and Teal Oasis. Retailers may carry only some of them; Black (A1657H11) is the SKU shown at B&H and Best Buy.

    Q5. How big and heavy is it?

    It measures about 95 × 51 × 32.4 mm (3.74 × 2.01 × 1.28 in) and weighs about 245 g (8.64 oz). It fits in a jacket pocket or a small bag, though it is thicker than a slim phone-only battery.

    Apple Watch Charging

    Q6. Which Apple Watch models work with it?

    Anker states compatibility with Apple Watch Series 7 and later that support fast charging. Independent testing was done on the Series 10. Verify how Ultra, Ultra 2, SE and Series 11 models are handled before publishing a full compatibility list.

    Q7. Does it charge older Apple Watch models such as Series 6 or earlier?

    Anker’s compatibility statement starts at Series 7. Older watches use a different, slower charging standard, so they are not listed as supported. Check Anker’s compatibility list or ask the seller if you own an older model.

    Q8. How fast does it charge an Apple Watch?

    The watch pad outputs up to 5W. Macworld’s test of an Apple Watch Series 10 reached about 65% in 30 minutes using fast charging. Speeds vary by watch model, battery health and temperature.

    Q9. How many times can it charge an Apple Watch?

    Greener Ideal reported up to 11 full charges of an Apple Watch Series 10 from one full charge of the power bank. Real results depend on your watch model and how much charge it has left when you dock it.

    Q10. Is it Apple-certified?

    The Amazon listing describes the pack as “officially certified” for Apple Watch. The certification program and wording are not detailed on the Anker page reviewed, so verify the exact claim (for example “Apple Watch fast charger certified”) before using it in copy.

    Q11. Can I use the watch in Nightstand mode while it charges?

    Yes, that is what the adjustable stand is for. It holds the watch upright so you can see the time. Nightstand mode itself is an Apple Watch feature and depends on your watch settings and watchOS version.

    Q12. Do I need to remove my watch case or band?

    Thin cases and standard bands are usually fine, but thick or metal cases can block magnetic alignment and heat the watch. Remove any accessory that keeps the watch from sitting flat on the pad.

    Q13. Will it charge an Apple Watch and a phone at the same time?

    Yes. The watch pad and the USB-C cable work at the same time. When both are in use, the combined output is capped at 24W, so each device may charge slower than when used alone.

    ---

    Phones, Tablets and Other Devices

    Q14. What else can I charge with it?

    Anything that charges over USB-C: iPhones with USB-C, Samsung Galaxy and Google Pixel phones, iPads, AirPods and other earbuds, Nintendo Switch, Steam Deck, and laptops that accept USB-C power at up to 20V. Anker also lists MacBook compatibility, though a larger laptop will charge slowly and may only be topped up.

    Q15. How fast does it charge a phone?

    The USB-C cable outputs up to 30W. Macworld measured an iPhone 15 at about 50% in 30 minutes. The actual speed depends on the phone’s own charging limit.

    Q16. How many times can it charge my iPhone?

    Greener Ideal reported roughly two full charges for an iPhone 16 Pro. Expect about 1.5 to 2.5 charges for most current phones, less for larger batteries and after conversion losses.

    Q17. Does it work with iPhone 13 and iPhone 14?

    Yes, with a separate USB-C to Lightning cable, because the built-in cable is USB-C. Anker lists iPhone 13 and 14 as supported this way.

    Q18. Can it charge a laptop or iPad?

    Yes, within 30W. Macworld measured about 35% for an iPad Pro 11-inch and about 26% for a MacBook Air (M3) in 30 minutes. It will not fast-charge a 65W laptop, but it can extend battery life.

    Q19. Does it charge iPhones wirelessly with MagSafe or Qi2?

    No. The wireless pad is designed for Apple Watch only. Charge a phone through the built-in USB-C cable. If you want magnetic phone charging, compare Anker’s MagGo Qi2 power banks.

    Q20. Can I charge AirPods or other earbuds?

    Yes, through the USB-C cable. The wireless pad is built for Apple Watch, so use the cable for AirPods and other earbuds.

    Q21. Is the built-in cable long enough?

    Anker does not publish the cable length on the page reviewed, so verify it before stating a figure. Reviewers describe it as a short cable that also works as a carrying strap.

    Q22. Can I replace the cable if it breaks?

    The cable is integrated and not designed to be swapped. Anker rates it for 10,000+ bends. If it fails within the warranty, contact Anker support. Verify against the user guide whether the pack also has a separate USB-C port for using your own cable; the pages checked describe only the built-in cable.

    Power Bank Specs and Charging

    Q23. What is the real capacity?

    The battery is rated 10,000mAh (37Wh) at its internal 3.7V cell voltage. Due to voltage conversion losses, usable capacity for a phone is lower, typically around 60% to 70% of the rated figure.

    Q24. How long does it take to recharge the power bank?

    About 1.5 hours with a 30W-capable USB-C charger (Greener Ideal: “about 1.5 hours”; Macworld: about 1 hour 35 minutes). A slower charger will take longer.

    Q25. What charger should I use to recharge it?

    Any USB-C power adapter that supports USB Power Delivery. The maximum input is 30W (5V/3A, 9V/3A, 12V/2.5A, 15V/2A). A higher wattage adapter is safe; the pack only draws what it supports.

    Q26. What is the difference between 30W, 35W and 24W in the specs?

    30W is the maximum from the USB-C cable. 35W is the pack’s maximum total output. 24W is the combined maximum when the USB-C cable and the Apple Watch pad are used together. The Apple Watch pad itself provides up to 5W.

    Q27. Does it have a display?

    Yes. Anker lists an LED display that shows remaining charge and charging power. Macworld describes it as a hidden display that appears when in use.

    Q28. Can I charge devices while the power bank itself is charging?

    Anker’s pages checked do not state whether pass-through charging is supported. Verify with the user guide before advertising it.

    Q29. Does it turn off automatically?

    Most Anker power banks shut off when the connected device is full or removed. Anker’s pages reviewed do not describe the auto-off behavior of this model, so verify before publishing.

    Travel and Safety

    Q30. Can I bring it on a plane?

    Power banks must go in carry-on luggage, not checked bags. At 37Wh, it is well below the common 100Wh airline limit. Airlines and countries have their own additional rules, for example limits on the number of power banks or on using them in flight, so check your airline’s policy.

    Q31. Is it safe to use?

    Anker’s power banks include multi-protection safety systems (over-voltage, over-current, temperature control). Anker’s own page for this model should be checked for the exact protection list before publishing. Do not use a damaged pack, keep it away from water, and stop using it if it swells or overheats.

    Q32. Does it get warm?

    Some warmth is normal when charging at higher outputs or when the watch and another device charge together. Keep it out of direct sun and avoid covering it.

    Q33. Is it water resistant?

    Anker’s pages checked do not state an IP rating. Treat it as not waterproof.

    Q34. What temperature range can it operate in?

    The pages reviewed do not list an operating temperature range. Lithium batteries generally charge best around 0-40°C (32-104°F); check the user guide for Anker’s exact range.

    Durability, Sustainability and Warranty

    Q35. What is it made of?

    Anker says it uses 75% post-consumer recycled materials in the housing.

    Q36. What is the warranty?

    Anker lists a “hassle-free warranty” and a 30-day money-back guarantee, with lifetime customer support. The warranty length is not stated on the page reviewed, so verify the term with Anker and your seller. Third-party retailers may offer their own terms.

    Q37. How many charge cycles will the battery last?

    Anker does not publish a cycle rating on the page reviewed. Lithium-ion power banks typically keep good capacity for hundreds of cycles, but confirm with Anker’s spec sheet before promising a figure.

    Q38. How do I look after the battery?

    Store it around 50% charge if you will not use it for months, avoid leaving it in a hot car, and recharge it every few months. Keep the watch pad clean and dry.

    Buying and Comparing

    Q39. How is it different from a standard Anker MagGo power bank?

    This model is built around the Apple Watch pad and a built-in USB-C cable. Standard MagGo power banks (such as the 5,000mAh A1618 or the 10,000mAh Qi2 models) attach magnetically to an iPhone and charge it wirelessly, but do not charge an Apple Watch. Pick this one if the watch is the priority and the Qi2 one if the phone is.

    Q40. Is it better than a separate Apple Watch puck plus a power bank?

    It replaces two items with one and avoids carrying a separate cable. The trade-offs are the higher price than a basic power bank and reliance on one device: if the pack is empty, both charging options stop.

    Q41. Will it work with a future Apple Watch?

    It is likely to work with future Apple Watch models that use the same magnetic fast-charging standard, but Anker only guarantees the models it lists. Check the compatibility page when a new watch launches.

    Q42. Where can I compare prices?

    Discompare lists live prices from verified merchants for A1657 so you can see the current lowest price and price history. Because Anker lists a reference price of $89.99, use that only as a rough guide and rely on live offers.

    Q43. Is it still on sale, and are there newer versions?

    Check current merchant availability on Discompare. Anker may release updated versions; match listings by model number A1657 so you do not compare it with a different product.
