  • Good, but not perfect.

    posted by redline48

    Gives the normal voltage and current, automatically turns off after charging. Optimal charge time. There is an entrance for use on 12V car power.
    Best charger I've seen for 18650 batteries. Russian Post was carrying a parcel for more than 40 days ...
    I hope this charger will work more than the other Chinese, burned after 6 months of active use.
  • Good quality for the cost

    - very small- good for pen laser pointers (but you need a spacer)- good for custom projects that require small size batteries- good battery
    Very good for pen laser pointers, but you need a spacer, so the battery can fit in the tube.You can combine more of them in series for greater voltage, or in parallel for greater capacity.
    Very good deal, you practically save money with these if you use them instead AAA batteries in lasers. But make sure you use only one (3,7V) with spacer.

    for now every thing is perfect.got it, used it,enjoying it.
    I am not sure about the capacity, but I don't really care. the price is so good that even if it is half of 6000 I will be happy/I got it for my 13000lm flash light. Just notice that these are fatter than the 18650 ones. so my charger can charge only two at a time and not four.
    I am happy. they should be ok for about 40min on my extreme strong flashlight, so I have already ordered 12 more batteries.

    good batteries that is used for alot of flashlights.
    the batteries seem to hold charge for long, i havent had to charge them since i first used them.
    these were suprisingly large, i havent seen 18650 batteries before and first thing i thought was "WOW"
    i used this with:
    and they all work good together.
    not sure if this is the best 18650 batteries DX has to offfer, but its the ones i bought and i like them. so far no problems.
