Enook S4 - Automatic Digital Charger

The Enook S4 charger is a fast (up to 1A x 4, or 1.8A x 2), affordable, and simple to use charger for both Li-ion and Ni-Mh/Ni-Cd cells. Just pop your batteries in, wait for it to detect them and you're good to go!

This charger also has a handy little function - Nocturnal Mode. If you charge your batteries at night and don't want to be bothered by the LED and LCD back light, turn on Nocturnal Mode and the lights will remain off until Nocturnal Mode has been turned off.*

    • What device/application do you use this with? Charging batteries for bicycle lights

    Very nice for the price

    I've only used it a handful of times on 18650 Samsung 35E batteries, but it seems to work fine.

    • What device/application do you use this with? batteries

    UPDATE------Failed after 1 week

    Wont stop charging batteries. Took 18650'3 to 4.3v and popped protection breaker on 4x new lg 3.4mah batteries. Took eneloops to 1.58v and I removed from charger. Probably would have burned the house down if not running protected batteries and watching eneloops.

    Hi Mike - Thank you for the input and the additional information by email. So far this is the only instance we know of of this happening. We are going to contact you via email about getting this charger back to confirm the issue and see what happened.

    • What device/application do you use this with? 18650, eneloops

    Very nice charger

    I got this charger because I have 3 other chargers that do not meet my needs. I need a simple charger that charges 18650's at 1a and AA eneloops at .5a. I want those Charge settings to be automatic. As an added bonus the screen has large numbers I can see from 20ft away. This charger will except 12v car chargers, which it DOESNT COME WITH, so if you are off grid like me you can charge without starting a big inverter. So I have run it though a few cycles and its all I need. Charged the eneloops in 2hrs and the 18650's in 1hr. I like this charger much better then the vc4 or efest. Worth every penny of the 17 dollars I paid.
