The 18650 battery charger, with its four bay is a smart choice: a universal charger for the Flashlight, Headlamp, security camera, ECT. Yes, we have the 3.7V Rechargeable Lithium Li ion Batteries and said unit is we hoped for, especially for the price. The unit charges fast and effective. Compatible with,18650, 26650 & 21700 Batteries. As you can see, each bay adjusts to the length of battery you may have, which is why we choose Tokeyla. Keep in mind, the unit is only USB Chargeable, not a direct plug to wall unit. However, the plus side is having four bays to charge at the same time. Quests, please ask. Amazon will patch you through and one of us wiull step up to help.

Bought this more than a year ago. Still working as well as the day it was new. No complaints and would recommend.

After looking at dozens of chargers & reading through their reviews (over several days just b4 Christmas late Saturday night) offered free 2 day shipping (prime members) but UPS dropped all the smaller packages to USPS which delayed it one day. The charger is significantly faster than the built in charger for each flashlight. Works for 16340 (Kodiak Kub) & 18650 batteries both used in flashlights. The cord is only 2’ long which doesn’t give much length so your outlet better be close or you’ll need an extension cord. I’ve used it several days now surprisingly able to use 1 hand to load/unload. Each port has an LED indicator to know when it ’s done! So don’t waste anymore time Searching this is the charger you’ll want. I recommend this product

I didn't believe another reviewer, but after testing the product with a multimeter I confirmed that the two center battery recharging points are reversed polarity, the two on the outside of the product are correctly labeled. It's a simple fix with a label maker, but sloppy and dangerous.

I saw the reviews that warned it was wired incorrectly, so I was cautious. Sure enough, 2 of the slots appeared to have reverse polarity, but, that's kind of like how half the time the plate rotates the other way in the microwave but it still cooks fine. I took mine apart. All 4 charging circuits are isolated and identical, yet 2 still showed reversed polarity. For an experiment I put a battery in the normal direction in one of the reversed slots, and it was fine. I can charge all 4 batteries in the normal expected direction and they charge just fine. I think these chargers ar ultra-smart and will change the battery in either direction. If you put a battery in backwards, it understands and charges it that way. If you put a battery in the correct way that's fine also. To those who think their slots are ware backward, just ignore that thought. Put the batteries in correctly (negative to the spring side) and watch your battery voltages as they charge. They all go up, even the ones you would have thought would be discharged due to a backwards slot. I could not read the numbers on the charger ic's but these are some very smart charger chips. Enjoy your charger.

Honestly can’t say anything bad about this charger, didn’t know what to expect for how cheap it was, but it 100% but the job! It’s held up for almost a year now and, no problems yet! I’d recommend if you want the basic charger for a good price!

Firstly, this charges batteries SLOW. The specs on the back of the charger list the output current as 0.35 amps per charge bay, not 500mA as advertised on the listing. That means it is taking almost a full 24 hours to bring an 18650 battery from 3.4v to 4.2v. This might be okay for some, but it's way too slow for my needs. Secondly, it doesn't seems to have a consistent voltage cutoff. One batch of batteries charged up to 4.35v before I pulled them off (they were still charging) and another batch would only go to 4.15v and the charger stopped charging. So for some reason it isn't consistent, and I don't trust the auto cutoff feature, meaning I have to babysit this thing while it's charging and remove the batteries when I leave the house for fear of overcharging and starting a fire. Thirdly, one of the bays stopped working almost immediately. I don't know why, but it started to discharge the battery and I didn't catch it until the battery was way down below 1v even though the led indicator remained red (indicating it was charging). The only way I feel like it is even safe to operate is by checking each battery with a multimeter about every hour, and I keep a fire extinguisher right next to the charger. I can't recommend this to anyone, it's just too unsafe. LiPo batteries can be a dangerous fire hazard if improperly charged/discharged/stored, and this charger amplifies the risk in my opinion. Do yourself a favor and spend a few extra bucks to get a charger that actually works.
