I have a anker bank with a built in usb wire, and for charging my iPhone, AirPods and GoPro, that has been super helpful, I might grab this.

I really like this one, my only wish is that the charging speed matched the discharge speed. 27W is annoyingly low, it means it takes almost 3 hours to charge this from 0 to 100%.

Probably my favorite power bank because of how compact, fast charging, and included usbc cable. It does not auto power on which may be a good or bad thing for some.

I figured with the specs that it should charge my smaller Dell laptop, but the portable battery runs down from 100% to 0% in about fifteen minutes without really charging the laptop at all.

works great for phones and regular devices though. just wide given the capacity

I have bought several of this brand over the years. None of them are in a working state…. Most just stopped charging. Anker for home use and nitecore for travel imo.

You should return or warranty it in that case. This battery pack is ~72Wh, so the 45W output, even assuming something low like 80% efficiency, should last weel over an hour. 15 minutes implies that there's something very wrong with the battery or they are massively lying about the capacity.

I had to look up this new rule separately. This makes all power banks that exist today illegal to travel with. That is wasteful AF

I ordered the 10k lanyard version. I worry about the built in separating even though I have the Anker Zolo which is also built-in.
