18650 Battery Charger 4 Bay Fast Charge, for 3.7V Li-ion TR IMR 10440 14500 16650 14650 18350 18500 16340(RCR123) Batteries, USB Intelligent Universal Rechargeable Battery Charger

I bought this to replace the 4 battery charger that I've had for the past 5 years. I was short on money but desperately needed a charger, so after reading the reviews, I went for it. I've had it now for about 2 weeks and I'm really surprised!! It works exactly as it should. I'm charging 4 18650 batteries for my e-cig and I always have a fresh pair of charged batteries ready to go. This charger does take several hours to charge, but if you charge at night while you sleep, then you will always have a fresh set. I give this charger 5 stars. Shipping was fast, it's very easy to set up, and use. I've had ZERO issues with it at all!!!

Initially when received, all lights remained red even with no batteries. I cycled power and restarted the charging process and everything worked and still works fine. FYI the device charges to 4.2 +/- .15 volts so you wont get a green light until this voltage level is achieved. Many of these charges are like this and I don't see any problem with it. Battery and Charger remain cool temp wise during charging and since you are charging from a USB charger I don't foresee an electrical overcharge potential or safety issues with this product.

No complaints. Charged all the good batteries and helped identify the bad ones. I recommend leaving it to charge overnight. Make sure that your charger is capable of supplying enough current! The smaller phone chargers may not do the job as they will take a very long time if you attempt 4 18650 at the same time. I like the individual battery status indicator! This is an essential feature in a multi-battery charger!

I've been using this for almost 2 months. It's not as fast as I hoped it would be but for the price is not bad. I've used a much faster charger but it was admittedly much more expensive. The plug fits rather loosely in the adapter so it gets knocked out fairly easy, no matter what I plug it into. I bought a few extra batteries on sale so I don't really need a super fast charger. I have enough now that I don't need to have a set in the charger all the time anymore.

I am so disappointed with this charger. Over the past 2 weeks, it was slower charging. I also had to constantly plug it in and out as it would stop charging. I should have returned it, but I wanted to give it a chance. Unfortunately, I missed the return window by 1 day. It never charged fast, but for the price, I did not expect a lot. I guess my expectations were correct. I decided to spend money on a well rated charger now and get rid of this one. I hate leaving a bad review, but this charger really should have lasted longer than 2 months. Lesson learned.

So far great product have used it around ten times and is working great

One slot doesn't work it doesn't charge battery

This charger works as advertised. The charger I had was lost/misplaced and I had no way to recharge my flashlight battery. Now I do, and it performed exactly as advertised.
