Q: Is this model included in the Anker recall?
submitted by pma - 1 month ago
A: Hi, thanks for reaching out about Anker 20000mAh 15W Power Bank - Black: Rechargeable USB & USB-C Device Charger. Yes, it's highly likely that the Anker 20000mAh Power Bank is included in the recent recall, but you must check the model number to be certain. Anker has issued a recall for several power banks due to a potential fire and burn hazard. One of the models specifically recalled is the Anker Power Bank (20,000mAh, 22.5W, Built-In USB-C Cable), model number A1647. To determine if your specific power bank is affected, you need to: Locate the model number: The model number (e.g., A1647) and serial number are usually located on the back or side of the power bank. Check the recall list: Anker has a product recalls page on its website where you can verify if your model number is on the list. The recalled models include: A1647 (Anker Power Bank, 20,000mAh, 22.5W) A1257 (Anker Power Bank, 10K, 22.5W) A1652 (Anker MagGo Power Bank, 10,000mAh, 7.5W) A1681 (Anker Zolo Power Bank, 20K, 30W) A1689 (Anker Zolo Power Bank, 20K, 30W) Verify the serial number: If your model number is on the list, you should then use Anker's online recall tool to enter your serial number and confirm if your specific unit is part of the affected batch. Important Safety Instructions: If your power bank is part of the recall, you should immediately stop using it. Do not throw the device in the regular trash or recycling bin, as it poses a fire risk. You need to follow Anker's instructions for proper disposal, which often involves taking it to a certified facility that accepts recalled lithium-ion batteries. Anker is offering a full cash refund or an Anker gift card to consumers with an impacted product. If you have any additional questions, we welcome you to contact MyTGTtech at 833-848-8324 every day, between 7am-11pm CST.

Great for charging devices on walks and I don't need to carry a charger block any more. Can survive falls and still works great. Pitty on the weight though.

Love it!
I bought this a year ago, specifically because we were traveling to Canada and knew we'd be in the woods for hours and would need extra battery for our phones. It worked perfectly. I'd charge it overnight and by morning it was ready to go. It charges a full charge for one phone and about 30% for another phone. And it takes about two hours to fully charge my phone. The only problem is that the screen was damaged, so the numbers are kind of cut off. But other than that, it's fine. I'll buy another one for my dad.

Power Miser: holds a lot of power; doesn't want to share it
This works great and seems to hold a lot of “juice” for my electronics. However, the speed with which it charges AND the speed with which it provides a charge are both INCREDIBLY SLOOOOOW. Painfully slow. Agonizingly slow. When I needed to recharge my phone while walking around Seattle, I had to leave it plugged in the whole time. Even when I wasn’t using my phone, it charged so slowly that after an hour, my phone’s battery level had gone up barely 10%. I should say that it charged my phone entirely at one point and the power bank’s own level went down minimally. So in that sense, it’s a great product. But if you’re looking for something that can charge rapidly so you can unplug right away, this isn’t the one.

Its a good purchase
I like how it keeps a good charge but it takes almost a full 24 hours to charge it to 100%. I don’t like that here is not any solar panels on it to charge the device another way. It is heavy so careful with it.

Very slow charging, decent large capacity
Be warned that this charges extremely slow. In 2025, nobody should be buying slow power banks. 10 years ago, you could probably forgive this, but certainly not in the new year.

This power bank helped me on my Tahoe trip in June. I love that it tells you battery percentage, what a convenience! Very bulky and first initial charge takes a while, after that you’re Gucci. Buy it when it goes on sale maybe around black Friday.

takes 16 hours to charge - if it does at all. i have plugged it in to charge before going to bed at night, only to wake up in the morning to find that is has not charged at all, for some reason. this thing is completely useless - if you need to depend on backup power, you will be in deep trouble if it’s this device you’re depending on. it’s 100% crap, not practical or even functional when you need it.

Does what it's supposed to
This thing works but it's heavy. It's definitely a carry in a backpack device more than a carry on a purse device. It is a powerhouse. But not one that meets TSA regulations for taking a battery on a plane. And I wish that had been more visible on the packaging
