The specified charging time of 2 hours is not achieved. A 18650 battery needs 4-5 hours to charge, not just a record. Who wants to see the positive: The 450 mA charge current are sure to conserve battery charge and the battery is not more than lukewarm. Structural weakness, as has been written in other reviews: the contact to the positive pole is a little weak, so that some battery must be carefully placed so that it loads.
The power cord is very short with 60cm, which can be a disadvantage or advantage. The housing makes a quite solid impression. What the supplied aluminum spacers are good, I can not say for my 18650 I do not need them anyway without guidance. The 12V input is only for narrow hollow plug, most copies from the junk box (such as for automotive DVD players) might not fit in there.
My rating:
(+) Compact, robust housing
(+) Works reliably
(+/-) Very short power cord (60cm)
(-) Charge time of 4-5 hours twice as long as indicated
(-) LED function very meaningful
(-) Weak contact the positive terminal can make some copies battery problems
