Byte, yeah I couldn't resists. Charging 4S packs with 50W takes ages ...

snellemin, ben je van NL naar Houston verhuisd?

I'll keep it in mind, altough it's a 250km drive for me which isn't free either. Think I will order 2 or 3 ... one for spare and another for selling.

I have a few old desk tops in storage that are not going to be used again. How can I convert one of those into a dependable PS for my charger? Thanks.
