Thunder Power RC Quad/4-Port Ultra-Micro AC/DC Charger Combo for 1-Cell/1S 3.7V Ultra-Micro LiPo Batteries, 0.3 Amp Charge Rate

I am very pleased with this charger and love how small this is. I've had it for 4 months now and its extremely reliable. I use this on my 120, 150, 160 and 500mAh 1 Cell batteries. For the 500mAh, you need the "JST-RCY to Ultra Micro Battery Adapter Lead".160's charge in 25 minutes500's in 65 minutes.I was also impressed with another thing. I put four 160's on the charger and forgot them all night long. They were on it for 10 hours before I realized I left them unintended. I was surprised to find that my batteries were just fine, worked great and have had no problems. Since this comes with no manual or information of safety features, I must assume it stops charging once the green light comes on.

If you are slight color blind like me? You will find this charger almost useless. When you put your batteries on to charge, the color of the LED's is suppose to be red. Then when the batteries are fully charged the LED's will change to green. I can most of the time tell red and green with no problem. But this charger's LED's are so very subtle with the color change, I can not tell the difference.So I don't know when the batteries are fully charged.So I did give the company a chance to respond to me about this problem. As I figured, no response! So now for reviewing this charger and seeing how the company responds or appreciate there costumer's? They failed the test as far as I see it? So if you buy one of these chargers, and some thing goes wrong with it. You will just have to eat it and don't ever expect to have help from the company. They will not respond to you........

I am currently on my second charger. The first and now the second have suffered the same exact problem. They both worked excellently for the first 6 months or so, and followed the same timeline of failure. All 4 ports went from working well to dropping off one by one. First the light (both red and green) quit working on one of the ports. Then another port will display a red light constantly with or without a battery present. No charge is being delivered there. So now 2 of there 4 are working. I give it 2 stars because I use this charger every bit of 6 hours a week, and for the price, they worked 6-8 months.

this will only charge batterys configured as the Thunder Power RC 160mAh 1cell/1s 3.7v G6 Pro Lite 25c Lipo's other variations of this battery size that have the ultra-Micro connector will not fit in the charger ! so not to versitile.

I use this several times a week. It works very well and I am glad I purchased it. However, for some reason one of the charge banks no longer turns green when charging is complete. The red goes out so I know charging is complete, but I don't like that the green light stopped working. For that reason I give it 4 stars instead of 5.

I got this charger because I have two RC planes that use little 1S 3.7v batteries and I wanted a good way to keep my plane in the air while cycling through batteries. This charger does the trick PERFECTLY. It comes with the AC wall adapter for charging at home, or via an AC adapter in your car, or you can go the route I do and use the alligator clips to hook it up to a 12v battery like those you'd find in UPS power backups. Using it that way, I can take a little 12v 7ah batterty with me to my flying field and use this charger to keep batteries for my plane filled up faster than I can use them.The use of the unit itself is very simple! Just hook it up to a 12 volt power supply, plug your battery in, and wait for the light to turn green for the slot that your battery is plugged in to. It charges each slot individually so you can have three green lights, and one red light. Just grab a green light battery to swap out into your RC plane (or whatever you're using the batteries in) and put your spent battery in the slot and wait for it to turn green again.Bottom line: If you want an inexpensive simple unit to charge up to 4 batteries at a time, independently, this is perfect. I strongly recommend it.

Does not work with Hubsan X4 batteries. So I will be returning this. Otherwise, it looks okay. I just have no way to test it and cannot find the correct adaptor to make jump leads.

I was looking at getting the Celectra 4-port charger and happened to stumble across this one day. For far less money it comes with both an AC adapter and DC alligator clips. The use of the product is pretty straight forward though not very detailed. For example, the main LED glows red indicating main power, the individual LEDs glow RED for charging and GREEN for charged. Nothing indicates whether the charger continues to charge once it is GREEN however.I was concerned because a previous reviewer stated it was not versatile in accepting micro connector batteries. I have four eflight 150mah batteries and five Turnigy Nano-Tech 160mah batteries and all fit and charge with no issues.I measured the batteries with a voltmeter after the light turned green and it charges both types of batteries to 4.20v which is the maximum charge for these LiPo batteries according to several forums. I intentionally left one on for an extra half hour and it read 4.20v as well, which leads me to believe that it does quit charging once the light turns green; this is only speculation though and you still should not charge batteries unattended. For comparison the Celectra 1-port charger that comes with many Blade Helicopters charges batteries to 4.18v and both advertise a .3amp charge rate.So far I am very happy with this charger as I have three helicopters that use these batteries and can fly until I get tired. I can buy about 10 more Nano-Tech batteries with the money I saved over my original choice of the Celectra. I even considered getting a cheap 10w solar panel and 12v battery to make a field charge station with this charger.
