I recently decided to get a good 4 channel charger that could replace my old 4 channel NiMH charger and my cheap 1 channel Lithium charger. Both of which were old, cheap, and feature-lacking. I was looking for one that could also handle LiFePo4 cells, and the D4 seemed like the only good option at $24 (as low as $20 elsewhere online).
Anyway, here are some nice features:
Here are some issues:
Something you need to be aware of is the fact that LiFePO4 cells must be manually selected and won't be automatically detected. The charger can confuse them for other Lithium cells and overcharge them unless you activate LiFePO4 mode.
Also, to use 750mA charging one or two batteries must be loaded on the same side of the charger. Otherwise, the charger will limit the current to 350mA as if there were four cells in it.
Overall, I'm very satisfied with my purchase, and it seems to work great. Since there are faster charging and more feature-rich Lithium chargers out there, I think I'd recommend the D2 over the D4 if you can go with a 2 channel. Otherwise, you might want to consider a 4 channel that can put out higher currents with all 4 slots taken to charge faster. Of course, I think these are the best options if you want to do LiFePO4 cells since that's a somewhat rare feature that most comparable chargers lack.

Anyway, here are some nice features:
- LiFePO4 charging.
- Constant individual cell charge level readouts without having to cycle through them on the LCD.
- It can charge every slot individually, so odd numbers of cells are okay without causing weird current issues.
- Able to charge Nickel cells at the same time as Lithiums.
- Looks very cool to me. I'd want an 8 channel wall-mount in my workshop.
- Takes 12 volts as well as wall power.
- You can lower the charge current for slots individually to protect smaller cells.
- The cool LEDs can be disabled to make it darker.
Here are some issues:
- The charge current decreases with the number of batteries you put in. 350mA is the max at 3 or 4.
- 26mm, C, or D cells probably won't fit well in this one at all despite descriptions.
- Similarly, 10440 and even 14500 cells are a little loose and might not make contact with the charger without lining them up a bit. Not a huge issue compared to other chargers.
- The stock power cable seems a little short at 3-4 feet.
- There aren't discharge/analysis features despite the fancy screen. Price is significantly lower than the ones that do though.
- Charge current can't go over 750mA for 1 or 2 larger cells. Other comparable chargers can.
