I am looking for a reliable (safe) mains charger for the single cell 250mah hubsan mini quad batteries.

I normally charge mine on my 12v lipo charger, but I have bought one for my nephew and I dont like the usb charger that comes with it as one battery I took of it was 4.5v and the charge light still hadnt gone off, so I dont trust it for someone who is not lipo savy like the rest of us.

I could get him a normal 12v lipo 4 button jobby with mains adapter but really want a plug into the charger and switch on as he is new to RC

I don';t know if there is something that fits the bill. All the ';decent'; chargers I have come across need some form of understanding to operate.

I';d be happy to buy your USB charger if your selling, mine seems to have vanished  :hmm:

PM me your address and I will post it to you

I use a USB plug.  Just a normal 3 pin plug with a USB socket in it - cost a few quid from local cheap shop.  Just connect the usual USB cable to it and battery, full charge in around 15 min :-)

If you have a look around EBay you';ll find chargers for those battery types.  Recently this topic came up on here and someone found a 6-battery charger, fully automatic.

Hi. I had the same concerns after some dodgy behaviour with my USB charger so I bought a skyRC quattro micro charger. It does 4x batteries at a time, each on it';s own circuit. It';s designed for 1s only and you only need to adjust the current for 1C or just under. So for my 380Mah (0.38Ah) its at 0.3A. It also gives you a readout on the amount of Mah that goes into the battery. I';m recording these to see how my batteries are degrading.

I also figure, since it does can handle 4 different types batteries it';ll be ebayable at some point.

Hope that helps  :smiley:

There';s a massive thread on RCGroups about the Hubsan x4 models and quite a few posts about the chargers. Someone did a dissection of a charger and found that the USB cable itself has a voltage regulator to turn the LED off at a certain voltage, but not the charge circuit! Original Hubsan batteries have over voltage protection built in (apparently), but this is no good for replacement 1s batteries!

I got a 4 way charger and spiced it onto some 4mm banana plugs to use on my regular lipo charger, set to 3.7v and it does the business no problems

Interesting both about the hubsan usb charger and the third party batteries
