I came across this while looking for a RCR123 charger that I could plug into a solar-charged battery pack with USB charging ports built-in. This was the only charger of the sort I could find. The picture shows it holding a pair of CR2s, but there are apparently screw-on size adapters that attach to the positive terminals in the charger, and those can be removed to allow it to charge RCR123s as well.
On the one hand, it looks like typical off-brand Chinese electronics. On the other hand, just the fact that some company thought to make this impresses me. Has anyone else ever seen it, or had the chance to use one? Any reason to think it might turn my batteries into blasting caps?
