There was a problem filtering reviews right now. Please try again later.
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).
Edit: the new item they sent has the cable working perfectly and fast charging.
I have used Anker products for a while. When I went looking for a more powerful back up battery, I started there. I needed something that could power - at one go - an Ipad, multiple phones, and a myriad of those electronics. This model does all of that. It holds up to the description, and I have had no issues with charging/recharging it like some of the reviews have mentioned.
It is relatively compact which makes it a great addition to my purse (both for everyday use and travel). The only thing I will make sure to mention is that it is not as lightweight as the smaller models out there. You can't get the charges it provides without a bit more weight (at least at this time). Just make sure you are aware this isn't a light weight model.

UPDATE: upgrading to an extra star for excellent customer support. This was originally 3 stars but upgrading to 4 stars. Customer rep reached out to give some options making things right for the battery pack not meeting expectation. Thank you for assisting me in this issue.
It's not super cumbersome, but I think that there are definitely smaller banks on the market that do the same thing.
That said, this powerbank has been working really well for me. It takes a while to charge up for sure, but lasts a good while and the USB-C charging port charges my iPhone significantly in a short amount of time.
Would definitely recommend if size is not a factor.
