im looking at picking up two of them they only like 30 bucks. but are they worth it i will be using them to charge tx batts and gens ace 5000 2s lipos. thanks whats the pro's and cons

I don't actually own one but in case you don't know; there are some knock offs out there. The way to tell if it is really from Skyrc is that it will have a holographic sticker on the bottom that reads Skyrc.

I have a buddy who has one. They work just fine.
