I bought an anker 13000 first, charged it over night(12hrs) the indicators never went over, charged my Huawei Nova 3i before it was full the power bank stopped charging. Just telling me both are 5v output doesnt say anything, and if your talking about a computers usb socket than those only output at max 500ma which is far too low of an output to fully charge that pack over a 24 hour period.

Mobile charging brands are defined as brands if more than 75% of their retail sales are contributed by mobile phone charging products. There is a limit on the size of lithium-ion batteries that can be taken on a plane without scrutiny, so to save the hassle I went with an acceptable battery capacity. The PowerCore 20100 should also be able to charge most small devices, like your smartphone, a few times over. The company has improved the design of its power banks a lot in recent years, and this version is the best we've seen yet. Compatible with most USB-charged devices, including iPhone 8 / X / XS / XS Max / XR (Lightning cable required), Android smartphones and tablets (including the Nexus 7), and iPads.Anker has a very confusing product lineup, I checked a number of reviews and the 20100 seemed to be getting the better reviews over the other 20000 Anker models. I would run it down and try with a different charger to to eliminate that part of the equation and see if it finishes in under 20 hours. Also it is not pointless to keep your batterypack charging if you choose to continue to use this wall plug, had you left it to charge the batterypack no doubt would have fully charged but you interrupted it by unplugging it. Mostly leaving this message for the benefit of others who might be Googling around like I was today.
