Looks a lot like the Trustfire charger i got. Ive purchased 4 of these and 3 work well. the other one was defective as it charged a 16340 cell to past 4.2 volts. i think it got all the way 6v. luckily it didnt vent or explode but its been replaced. the lights did not turn green just staeyd reddish green.
The batteries in both sets have the same "3600 mAh" wrappers, but one is 'actual 2200 mAh' and the other 'actual 1300mAh'....ie rubbish vs complete garbage.
