Very happy with the NPB4 Waterproof Powerbank.
Robust, Fast Charging, has USB C connection, & the cloth bag/case provides extra protection as well as being easy to attach to – well anything..!! I get just over 2 full charges of my Samsung S21 Ultra, so I have power for 3 full days .

Great power bank. It is a bit heavier but has such great charging capability. My favourite bit is the molle case that comes with it so I can attach it to the outside of my backpack.
