To me this is an interesting question. Theres alot of talk that although there are lots of brands of Lipos they are all pretty much made in only a few places. Now looking at the various chargers available they all look very similar.
I've got an Orion charger but I bought it because it has the A/C plug. Theres a couple of chargers out there that look exactly the same as the Orion charger. I've also got a Turnigy 12V powered charger and that looks identical to about 80% of the charger we see these days. Gone are the days when you'd turn up at a meet with a ProTrak or a Turbo30 if you were particularly flush and folk would know you meant business
