May not give all 5 amps – DIY 5A Constant Current Constant Voltage LED Driver Li-ion Battery Charging Module Reviews

posted by Panther37 on 08/19/2013 Certified Owner

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Pros:
- Small - Red - Screw terminals are great, permanent and easy to remove (unlike solder) - Extra hole terminals (for test leads) - Power and load LEDs are different colors
Cons:
- Volt and Amp adjusters aren't labeled (Not THAT big of a deal) - May not give all 5 amps - Gets pretty hot
Other:
I bought four of these to take 12.5 volts (from my car) and turn it into 3v, 5a. Only one of these can do this. Two of them give me 3v, 3.9a and the last one won't supply any voltage at all.
Bottomline:
Great little gadget... if it works correctly.
