Review: Best charger - For me Anker make the best portable chargers. They have fast charging and is light weight. Great size and can fit in your passport bag when traveling. You can charge your phone empty to full around 3 to 4 times so lasts a long time as well.
Review: A good backup to have at all times. - Really good power bank. Works well and has been used with iOS (mine), Fire Tablet (son) and Android (my partner) devices without any issues. Charges reliably and holds a good amount of power. It’s solid without being too heavy and fits nicely in a bag for travel or days out. Handy for keeping phones, and other bits charged when you’re away from a plug. The build quality good quality and it’s held up well with regular use. Definitely worth having around.

Without doubt, the best power bank I have ever had. This holds it's charge like a demon. Great recharging of devices. Well designed, easy to store and an essential back-up power supply.
