Cheerwing 4-in-1 Charger and 4pcs 3.7V 650mAh Rechargeable Lipo Battery for Syma X5 X5C X5C-1

works well

perfect fit.

The charger works as stated. Satisfied with the price and the spare batteries are operating well.

UPDATE: 5/2020 The company was very responsive with any issues. They promptly sent me a replacement charger, power cable too. No hassles! Now it works as it should. Charges 4 batteries, all indicators on and shuts off when the battery is full. Handy if you want plenty of fly time.Original:Well, I liked that it was a charging hub for 4 packs at once. The more packs you put the longer it charges though.However, after the 1st charge, the thing went crazy and now it is down 1 port 2nd to the left. Not only that, it's strange. Plug in a battery pack without being plugged in, an indicator or 2 lights up. I can't make heads or tails why or maybe because this is defective. I. Tried all single packs to test the relative indicator and charge and it seems at least the packs work for now. So as of now, the charger seems malfunctioning.I emailed the company to see what they say, I will update when or if I get an answer. For now, 1 star.

This item was purchased to replace LiPo's that have expired for my child's drone. It was ready to go out of the box, quickly charged, and the drone is flying again.

Very good they last for a long time. Totaly should buy this cheapest option I could find.

Battery that came with the drone initially lasted for quite a while. First set of replacements had 2 out of 4 not holding a charge but the other 2 lasted for a bit. Second set of replacements were all dead or dying from the start and I returned them. The replacements were even worse and I never returned them. So I have a drone with no batteries. I keep planning on ordering another set but have zero confidence in them being good batteries. Battery life doesn't deserve a single star.

Two batteries took a charge the other two after numerous times of trying to charge them, thay will not charge both of them remain dead
