MagGo Power Bank for Apple Watch, 10,000mAh 35W Max Portable Charger

UPDATE: Anker reached out with top tier customer support. They helped me troubleshoot my slow charging speeds and it’s just that the watch itself is designed to charge at different rates depending on several different factors. They explained it very clearly and in a helpful way and it was enough for me to just keep using it in good faith. I can safely say this thing works pretty well especially by comparing it to other chargers. I tried to use other watch chargers with a wattage read and found they were the same as well with slow charging speeds. After taking this on multiple trips, it will definitely charge your watch in a pinch. I may have just had some errors in my first overnight charge but after putting it through its paces, I went a full 5 days just using this to charge my watch and even my phone once or twice and it saved me packing a two cables or fighting someone for an outlet. Is this worth the full price tag? I’m not exactly sure. I think I found my value out of it. Basically saves you from packing or buying a watch and usb c cable. Plus it has enough capacity to charge my watch several times over. Really no more complaints! Okay so two things here. I bought the other battery which has the same built in cable, but features a wall outlet plug in. Super useful when travelling. No fussing with a power brick or worrying about forgetting it plugged into the hotel wall, but whatever. Then I saw this. I was annoyed because if I had seen this one that has a watch charger built in, I would've scooped this up in a heartbeat! Against my better judgment, I bought this one too and gifted the other charger to my girlfriend. Sadly I did realize that this battery bank doesn't have a wall outlet charger. Not really this thing's fault, it doesn't advertise that it does, but man I just saw the same style battery and thought it did. Bummer. Not a big deal. What IS a big deal is that this thing comes with little circle stickers for you to put on the watch charge to help "stabilize" it. Usually a red flag when a product has a "fix" for an issue, but whatever. I love Anker products. I apply the sticker and plug my phone in. The phone charges at about 20w which I can see because of the neat little digital readout. Super cool. I have one of those cables that reads out the wattage and can confirm, I plugged it in to charge at 30w, battery confirms 30w, and even better yet, it gives an estimate to the battery being full. Very neat! Now for the terrible part. I popped my watch onto the charger....it charges at .8w. That's right. Not the max 5w, not 2w, not even 1w, just .8w. To give you an idea of how "fast" it charges, I put my watch on the charger at around 80%, went to sleep, woke up about 6 hours later to a 94% charged watch. Now I figured, maybe it's because my watch is nearly fully charged. Today I put my watch on there at 10%. Still .8w. I moved it around for a bit and I got up to 2w. Then it'd drop back down to .8w. I took the sticker off, no change, applied a new one, same result. Despite having some cool features, this is a return for me and off to find a replacement!

Great power, cool cable design, very sturdy, not too light, not too heavy, compact but bold, charges two to three items such as Watches, iPhone and iPad at the same time via wireless charger and USB C Cable. Wireless charger speed is fairly fast and its very similar to Anker desktop charger. The USB C charger are definitely strong enough for a fast iPhone charge on the go. Anker products they always retain battery very well and discharge very little while you carry them around for days. I always take this to my short and long trip bc I can charge my phone and watch at the same time and it does give me more than 75% charge which is enough for one day out in the city or trip. This should be used in your backpack all day long bc its very portable and easy to carry and it has the USB C cable and watch charger built in. The Watch Magnet is very strong so I just wrap my watch around it and put in my backpack zipper and it keeps charging. The Cable turns into a handle which is very innovative. Its very strong cable so dont worry playing around with the loop cable, it wont tear apart. Overall I am very happy with this Anker charger, its very durable and seems quality built. I think its a great value portable charger. Get it while on sale to maximize the savings.

I love Anker products and this power bank did not disappoint. It charges my Apple Watch while I was at work and topped off my iPhone to get me through the day. The watch charger can be flip up like a stand. The invisible screen is so slick and tells you what’s the charging rate. It is small enough for any bag or backpack but not slim to carry in your pocket.

Most versatile power bank I've ever had! Great capacity. Strong cable. And the ability to charge my watch on the fly gave me needed peace of mind when traveling. On my trip, I would plug in my wall charger. Plug that into this battery, and from there charge my watch and use the built in cable to charge my iPad. It allowed me to minimize what chargers and cables I needed to bring. But the cherry on top is the display. I've never had a power bank give me this detailed data before. It can display power remaining, but also the wattage of the input OR output. It'll even tell you how long it will take on a charger to replenish itself.

I love this thing! It's my go-to on-the-go anything charger. I'll get out of the way first that its one drawback is its kinda thick and a tad heavy, so it won't fit well in your pocket. However if you keep it in your bag and run a cable to it, then it'll work like a dream. So this is fantastic at travel, mobile office, or college type working. It was fantastic when I took it on a long train ride, but a pain to bring along in my pocket for a Pokemon Go marathon. That said, in every other way this is a one-shot perfect power bank. It has a built in apple watch charger (which has almost replaced my normal charger), it's built-in usb-c cable/tether is pretty strong, and its display screen is gorgeous. Not to mention at 30-ish watt in/output this thing is actually a bonafide fast-charger. If I'm in a hurry for a top-off I'll plug my phone into this instead of its normal charger. I think if Anker had cut the power capacity in half to only 5,000mAh so it'd only be half as thick/heavy, it would've been perfect. Speaking of though, I love Anker as a brand. They build quality products, and the *one* time I ever had something of theirs break their customer service took care of me right away. So if you need a charger for your carry-on or backpack or purse, it's perfect. If you need a charger in your pocket, then it's doable but less than perfect.

I have an iPhone 13 Pro Max so I had to buy USB-C to lightning cable to charge my phone. From 22% battery on my phone, it took a little over 1.5 hours to charge it to 100%. The charger was at 100% when I started charging my phone. By the time my phone was fully charged, the charger was at 60% The size is compact and I was able to fit the charger and extra cable in my fanny pack that I use for work. It’s got some weight to it but I don’t consider it to be heavy. Because I work lots of events I’m not usually near an outlet, so I appreciate the convenience of this charger. I have been in situations where my phone and watch die one after the other which is what prompted me to buy this. Being able to charge my Apple watch, phone, and iPad at the same time makes it worth every penny!

Love this Anker battery bank. I never leave without it. It charges my iPhone 16 max from 40 to 80 in 10 mins and has still plenty of charge left. I probably get two iPhone chargers in a day if needed. The included cable length is a nice length, and it doesn’t get in the way. One less cable to carry. It doesn’t tend to get warm or hot while recharging. Very convenient to have for emergencies. Not very bulky can be carried in pants pocket without any extra bulk.

12/3/25 Anker replaced via warranty on my first call. Very positive experience. They had me place the C-usb into the C-usb port. This was a successful reset for a while. The leds went out on the front and can no longer see status. 8/16/25 UPDATE: Not charging or giving charge to devices. Only charged on Anker surge protector. No reaction when pressing power button. Showing 66% and front graphics no longer powering off or changing status. Outside of return window. I will update once there is more to tell. A gorgeously beautiful and portable power bank. Anker is authorized by Apple so buy with authority knowing Anker built it with easy to operate design for everyday use on the go. Best options I could find with built-in single C/iQ3 in/out cord, Extra C/iQ3 in/out, and built-in Apple Watch charging. Bottom feet where a very useful design add as they kept it from sliding off the surge protector, which was not on a flat surface, while charging with the attached C/iQ3 cord. Gives you most complete information on battery status I have ever seen. You will not regret this purchase as I have a Anker power bank from over 5 years ago with a miniUSB that is still going strong and charging up my devices quickly.

Really useful fast charger. Works really well for phone and watcb. It’s my 2nd one and can’t fault it. Stylish compact and really useful as my phone drains really fast.

Snabb leverans och bra produkt

İndirimli fiyattan almıştım gayet güzel iş görüyor

A mi madre se le ha olvidado que es el CARGADOR y solamente carga su celular y su Apple Watch todos los días con esta madre en vez de usar el cable y el brick como toda la gente pero bueno dice que es fácil así yo que se la verdad le ha aguantado mucha batalla y sigue cargando igual después de varios meses tanto así que mi padre me ha pedido que le compre uno a él NEGRO porque obviamente blanco no lo traerá el sabes

Małe i wygodne urządzenie. Świetnym rozwiązaniem jest, jak to w Ankerze, wyświetlacz który prezentuje poziom naładowania powerbanka z dokładnością do jednej setnej procenta (przy jego ładowaniu) i oczywiście moc ładowania na wyjściach w tym na MagSafe do Apple Watcha (w tym przypadku do jednej dziesiątej wata).
