My power bank suddenly split at the back
Hey guys thanks for all you do all this while? I can't appreciate the reliability of your power bank enough. My power bank suddenly split at the back and I'm scared to charge it with the fear that it will explode, what should I do? Thanks.
Thank you for your feedback

Plenty of power to recharge an ipad or iphone. Enough power to substantially add battery life to a laptop.
The power bank is small for what it does and I think the size is quite nice, but others may feel it’s a little too heavy. I do not think most people would be disappointed at the size considering this is 20,000mAh.
It holds its charge when not being used for at least a week or two (I have not had it long enough to test it for longer periods yet.)
It does not run hot.
The only relative negative is that it takes about 4.5 hours to recharge from empty. This is not too long, but may require some planning depending on the situation. Other power banks are out that can recharge faster, but they are heavier, more expensive, and may require to be plugged into a high powered charger in order to obtain the faster charge.
This power bank is inexpensive for what you get. One very nice thing is that this charges through C to C, C to lightening, and not just USB-A.
I do think the shipping took a couple of extra days versus 1 day, but this was disclosed when I bought it.
It did arrive on the day promised.
I highly recommend this power bank for anyone that needs more than a daily phone charge. Great for traveling, long airplane flights.
For a daily phone charge get the Anker with 10,000mAh and C to C charging (in and out).

As a training Pilot, I depend on this battery pack to keep my iPad alive in the cockpit, and this pack has saved me a couple of times! I’d recommend this product to anyone. It charges quickly, and keeps the IPad alive for quite a while. Well done Anker!

It works flawlessly; keeps a charge for a while and charges things very quickly. THIS IS NOT DESIGNER FOR LAPTOPS. It will charge a laptop, but VERY slowly. It's powerful with phones and tablets, maybe some headphones that you can recharge with a cable. It's a little large and heavy, but it's worth it for an extra punch of power. The texture is nice to hold, and slips easily in and out of the carrying bag it comes with. The ONLY downside(which isn't that big of a deal) is that it'll take a few hours to recharge the battery pack. Leave it overnight and it'll be fully charged in the morning.

This is my favorite item in the world! I took it on a trip to México and it never died on me. Bought it in May 2022, now in May 2024, and it still works great and holds a charge for a long while. Now my husband uses it on business trips. Perfect to use at airports, airplane, long walks, any time you're out all day. I'm about to buy another for my husband to have his own.

This was my first experience with Power Delivery (PD) and I'm very impressed. It's capable of charging all my devices. It charges my phone (10W), Nintendo Switch (18W), and laptop (65W). Note that the laptop slow charges since this battery bank can't put out 65W, but it's still fairly quick. With PD, I no longer have to carry around two or three wall chargers, cables or battery banks when I travel. I don't even need my original laptop charger anymore which saves me a ton on packing space (I bought a 65W PD wall charger to go with the battery bank). Simply put, PD is awesome and it's definitely the future.

The size of the bank is somewhat large. Similar dimensions to a large cellphone with a thick case. I don't think it's too large though. It fits in my standard Nintendo Switch carrying case without putting pressure on the joysticks or screen.

The battery life is very impressive. Off of a full charge, I used it to charge my laptop from 65% to 100%, my Nintendo Switch from 27% to 100% and my phone from 19% to 100%. It's indicating that it still has 50% left on it (two blue LEDs).

I did experience one small issue. My phone will not charge off of the USB-C PD port (Motorola G Power 2020). Other devices work fine off that port. I believe this is an issue with my phone and not the charger. Maybe Motorola used a proprietary fast charging system for this model or maybe PD doesn't work with older devices. My phone works with the USB-A port though. It will actually display TurboCharge on the screen, which I haven't seen before even with the original charger that came with it.
