CasePower Street Compact 4000mAh BLACK Slim Dual Port Power Bank 2x 2.1A Fast Charge Durable

This is a great power bank on paper: 2.1A output, two USB output points, and 4000mAh. The only problem is that unlike similar models, it doesn't have a row of lights on the front to show how much charge is left, nor to tell you if it is even charged. Having said that, it works well, and charged my iPhone 7 from flat to 100% in 2 hours, and had some charge left after that to top up a second phone. It comes with a karabiner which is very handy. The construction is solid and it smacks of quality and robustness. The torch is OK but not amazing, and you need to keep the button depressed for the torch to work.

Brilliant so glad I got one

Adequate for what it is and needed for
