The Nitecore UM10 is a excellent charger that shows the percentage and is accurate even at 1%. This charger is not very sought after because of the fact that it only can charger one battery at a time, but don't underestimate this little beast of a charger. It will charger even your phone and battery at the same time, but when there is an efficient amount of power it will go into priority mode and charge your phone first and when that is done it will start to charge the battery after. And the UM10 even acts as a medium for data transfer.
