After using an Anker PowerCore 20100 for several years it’s still going strong, This product is a hugely successful one with thousands of them sold. I’m a big fan of Anker products I’ve bought several other items by them and they always impress with quality and purpose. The power banks are very useful when travelling or on camping trips etc. They are pretty tough with the kids using them and chucking them around in bags sliding off onto tiled floors. I have to admit sometimes they haven’t been charged for 12 months and they still work as they should when we need them.
Having a range of lights showing the charge level is very useful. As I know three lights is plenty of power.
When I have camped out in the Welsh outdoors in below freezing conditions on a mini adventure the power bank performed as expected with no issues. On the flip side they have been used on the pool side in hot climates.
