Hi Harry, It needs a stable power source between 10vdc-15vdc with the right coaxial plug. HK's basic 60W Power Supply (PRODUCT ID: 9052000014-3) will do the job, but you're paying more for the power supply than you are for the charger. If you have a computer repair shop near you, stop in with the charger and ask them if they have a used one they can sell you for a few bucks. It needs to be a regulated power supply, not a charger pack, because the output of charger packs fluctuate and will cause an error message (ER2). Cheers, EA!
Hi Olga, You can charge a 5000mah/4S, but it will be very slow and will take up to 4 hours if the LiPo is fully discharged. The max charge rate for this charger on a 4S is less than 1.5A, but you could charge a 5000mah at up to 5A in under 1 hour with a higher wattage charger. Have a look at the low-price multi-purpose chargers like the Accucel-6. Cheers, EA!
Hi Justin, An ER2 error message with this charger almost always means the problem is in your power supply. You say your supply is tested, but do you mean you turned it on and measured the voltage output with a meter? You may get 12.5V at the plug but when you plug it into the charger and it's under load that voltage may drop or fluctuate. Use the cable that came with the charger to run it from a car battery. If the charger works that way then the problem is your power supply. Cheers, EA!
Not a good charger. My charger is not charging my LiPo's anymore. It doesn't come with any manual or any review and it is giving errors that are totally unknown like "Er0","Er2". For warranty it costs very much than the charger cost.

Do not order these pieces of crap.
They fail within 1-2 weeks, and return shipping is nearly (or higher than) what you will be refunded.

Excellent charger, very fast and accurate. Robust metal housing. The maximum charge is 4.20 V per cell saves the batteries. I recommend! POL88/Sailor NAVIGA /

Excellent charger! Kind of like the CopterX charger but better.
1) End voltage from charger 3s 750mah: 4.20, 4.19, 4.19
2) Charger beeps when battery at full charge
3) Can use this as cell checker at the field
Very handy item. Get warm just like most basic chargers, that's fine. Does not overcharge or undercharge, which most other similar chargers have (CopterX, ESky..)
