Pros:universal charger, gives you a possibility to charge wide range of LiIon cells and can be used in car or with AC mains. gives 5.3V on open circuit.- low charging current, gives me 360mA, so it is ok to use it with 10440;- no trickle charge;- cut-off at 4.18A both channels;
Cons:- doesn't fit trustfire protected 18650 (neither blue nor black, they are up to 68mm max), need to disassemble and modify body to give more space for sliding contacts;
Other Thoughts:side contacts can be soldered easily to charge 16340 but it is better to leave them as is and use a spacer for these purposes - there is no polarity specified on charger's body for these contacts. also you can accidentally make a short circuit for 18650 with damaged envelope.
Bottomline:imho the best LiIon car charger on DTW.

Pros:Easy plug and play charger, light turns green after being charged.
Cons:Take a long time to charge high capacity batteries.The charges at 5mA only which can take a long time to charge.
Other Thoughts:If you serious about charng li-ion batteries buy this.http://www.dealtoworlde.com/details.DTW/sku.15225get 12-15v power supply rated 5AMP or higher.Build a battery holder for your battery type.Tell the charger you charging li-ion enter the capacity and go. your cell will be charged in 1hr.
Bottomline:Good charger if you can leave it, but I know enough to get in trouble. :)
