AnkerMagGo Power Bank for Apple Watch, Officially Certified 10,000mAh Compact Battery Pack with Built-in USB-C Cable, 35W Max, for iPhone 15 Series, Samsung, iPad, AirPods, and More(Black)ClimatePartner certified

Small and compact, a little on the heavier side but overall it’s the best battery pack I’ve owned. Charges my phone about 4 times before it needs a recharged. The display is bright and shows the percentage and how long it will take to recharge. I lobe the built in cable that also works to carry it. Perfect for travel!

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!

I have plenty of power banks. I was looking for another to travel that could also charge my Apple Watch. I saw this power bank and decided to purchase it.I have many Anker products. All of them work very well and this power bank is no exception. I have tested the charging speed, and it definitely charges at the rated 30W. It also charges my Apple Watch extremely fast which makes it perfect for travel when I need a quick charge.The unit isn't too big. It has a different dimension then most power banks. It's a little fatter and not as long as others. The size and weight are not an issue for me. It fits well in the pocket and you can use the included USB-C cable to carry it around if needed.Overall, a great product and another home run by Anker. Highly recommended.

Very well made and I like the flexibility of how to set it up based on if I’m charging my watch or not. I like that the cord becomes a carrying loop as well. It’s well made, and I’ve used it and charged it several times and no issues. I really like the digital display showing how much charge is remaining - that’s something most don’t offer so it really helps knowing how much more charge I have before it needs to be charged. It’s small enough to put in a purse or bag for travel. I plan on using it for the year and then buying it for stocking stuffers if it holds up.

This charger is incredible. It’s incredibly portable, and I love how long it lasts. It’s durable and lightweight. I can charge my phone twice or thrice, and my watch over ten times, because of the low wattage required for charging.
