Just touching base with you on the xtar WP2 because I'll be looking for a backup to my Pila soon. Can you provide a brief review?
I was using the TR-001 before I got the other cheap charger I mentioned earlier, and the xtar blows it away. This is, IMHO, a great charger. It charges 18650s in less than 1/2 the time as the tr001. I'm using and charging all diff combinations of batts simultaneously. I can have a 14500 in slot 1 and an 18650 in slot 2. The batts never get warm they are reading right at 4.18v consistently. I would highly recommend it.
Keep in mind I'm a self taught, moderatly experienced newbie with days and days of reading and asking questions of the experts. I guess thats not self taught.
