  1. The Best battery and charger ever!!!!! 5 Star Review

    Posted by on 29th Jan 2016

    I'm a policeman and I'm very happy that I can charge my battery in the comfort of my police cruiser, thanks to the USB adapter on the charger. Even charge my cellphone in an emergency. My TN12 2016 is working great with the Thrunite 18650,3400mah battery. It's give quite good running time. Thanks Thrunite for make my Night Shifts at the police department of Puerto Rico more secure. I trust you and I know that when my life is in danger I can depend on you. Thanks again.
