Compact Charger August 12, 2019
Reviewer: Robert Gannon  
Nice charger at an affordable price! Small enough to take on the go. USB input works just fine in my car. No bells. No whistles. It just charges, like it's supposed too. I use 20700 batteries and they fit perfect. The only issues I have at this point is the fact that it charges 20700 3000mah batteries very slowly. It will not charge ANY battery if the USB adapter you are using has an output of more than 2.4 amps. I have tried several. The light just blinks and it refuses to charge. Which it doesn't come with btw. But I didn't expect it too at the price I paid for it. Awesome shipping! It came a day early! I will certainly grab another one in the near future from 18650!

Awesome August 6, 2019
Reviewer: Jeffery Robinson from Trussville, AL United States  
I was looking for a battery charger and I saw this Efest so I decided to purchase it ... It’s excellent in my opinion ... Charges my batteries really quick ... Shipping was insanely fast too ... Only took 1 day for me to receive it ... Highly recommend this website ... I’ll definitely purchase from them again.

I haven't had to use it yet, but it is simple enough for even a 73 year old lady to understand. Thanks
