Now that this thread has been bumped, I'll give my input since it seems like a good thread. We sell
Nitecore and
Efest. We chose those two because in my opinion the Nitecore I2/I4 are the best budget chargers out there. They're cheap and work well. Downsides are they don't give you much info on what they're doing and they're really slow.
For people who want something more upscale, we recommend the Efest LUC line. This is what we use here. They're awesome chargers, with a full voltage readout and the ability to change the current from 0.5A to 1A or 2A per channel. The Nitecore only does 750mA per channel, and only has 2 channels. So for example on the i4 if you have 2 batteries charging they'll charge at 750mA but if you have 4 they'll charge at only 375mA. The Efest lets you choose and for many batteries 1A is great. Also another kinda cool feature is the efest can act as a portable power supply if you leave the batteries in it to charge things off of.
One other thing to keep in mind about chargers is that Nitecore is VERY heavily counterfeited. We've been going crazy recently after having bought a whole truckload of chargers and then doing our usual teardown found they were actually counterfeits. You never would have known it from the box or looking at the charger itself without pulling the circuit board out, and even then we were second guessing because they even went to the extents of branding the capacitors on the board with Nitecore branding, and branding the circuit board, etc. Ultimately we figured out they were definitely counterfeits though after talking to Nitecore engineers. Our stock right now is direct from Nitecore.
Luckily Efest doesn't seem to have that problem yet.
So anyway yeah, if you're on a budget go Nitecore (but be careful of counterfeits) or if you want the best IMO go with Efest. XTAR is another good high end one but we don't carry that since to us the Efest seemed a better value.
