2-Bay Smart Li-ion Battery Charger, for 18650, 26650, 18500, 17335, 3.7V AA, AAA Rechargeable Lithium Batteries, Flashlight Torch headlamp Charger, USB Port Dual Channel with LCD

When I ordered this I thought it was a plug in the wall type charger, however it is not. It does require a 1 or 2 amp usb power supply The price is right for not having a charger with it. If your like me, you probably have 20 laying around anyway, way to save. Only used it a few times. It shows you the voltage, and charge time while charging, and it also show the timer. I charged two 18650 that were near dead, they took 6 hours with a 1 amp usb power supply. I would guess with a two amp it would cut the time in half. It charges each battery separate, (at the same time) so each one gets fully charged. Some chargers will quit charging when one battery is charged, and the other does not get fully charged. This one does not do that. Over all so far I am happy with it! I would recommend it. I am one that uses items and manage to find needed improvements, I have not found any for this one yet. With time I will probably find it. I will update this if there is anything significant. If you need one of these chargers, go for it!

I have an extra pair of 18650 that I wanted to be able to charge outside of their intended device, whether I'm out and about and only have my battery pack, or at home, by my USB hub. There are a few options on Amazon but I liked the price and the easy, clear display of this one.The good:Construction quality seems good, the springs that hold the batteries in place have some bounce to them so the batteries don't easily fall out during use. The rest of it is in a pretty succinct package, not much space is wasted. As previously stated, display gives you all the good info, looks great, just the right size.What could be improved?Please note I'm still giving this thing 5 stars. I bought it to charge batteries, it does. However, I wish there was a family tab or someway to remove the batteries besides rolling them out or the ol' banging it against the opposite hand.I'd love to be able to check the battery levels without plugging it in, if that amperage output selector button could also just turn on the display for 5 seconds when not plugged in, that would be useful.Company name at the top of display is in Comic Sans. I'm sure we can do better than that.

Pros: Shows Charge Percentage with nice digital display along with voltage output (increases with charge), not gonna lie, it's pretty nifty looking. Total charge time for 3600maH 18650 batteries - about 3 to 4 hours.Cons: Kind of difficult to get the batteries out, a ribbon under them helps with this, but the springs are very strong and if you're not careful it will slamshut and scratch the plastic coating off the sides of your battery (which is very bad), No AC DC adapter to plug it intoHigh quality, just wish they came with an adapter, had to find some old phone chargers that met the specs on the box. USB on your computer is not enough, 500ma for USB 2.0 (1/2 of recommended amps) and 900ma for USB 3.0 (100 ma short of minimum requirement). Will probably work with your computer, but will charge properly with a phone adapter, just read it makes sure the block says Output: 5V and make sure the amps are between 1A and 2A. Example: Output: 5v==1.2A Not sure why they didn't include one, I mean they're literally a dollar, and there was plenty of room in the packaging. I would have paid an extra dollar not to have to dig around for old cell phone adapters.I bought two, tested it with identical sets of batteries at the exact same charge level and maH, and it doesn't charge any faster with 1A than it does with 2A. They finished within two minutes of each other.

Works great so far. I use it for my LG 18650 high drain batteries. The display is brighter than what is shown in the picture (make sure it isn't in your FOV when you go to bed) and it shows all the info I need to know about my batteries as they're charging. And it uses a standard micro USB cable to charge, so for me I can take care of all my device charging needs with one type of cable.Only issue I have had with this product is that I need to be mindful not to disturb/turn the batteries while the charger is plugged in as this seems to disrupt the circuit at least momentarily. IMO this isn't a big enough issue to warrant taking off a star (I should never need to touch the batteries unless I'm swapping them out anyway) but if it gets worse. I'll update this review.

2-Bay Smart Li-ion Battery Charger, for 18650, 26650, 18500, 17335, 3.7V AA, AAA Rechargeable Lithium Batteries, Flashlight Torch headlamp Charger, USB Port Dual Channel with LCDThis is a great charger for Li-ion batteries.Unlike most other chargers with a red or green LED to indicate that the batteries are charging or fully charged, the lighted display of this charger gives you all the charge-status info that you would want regarding each battery.The company says "the charger can only charge Li-ion batteries", so I would not try it on other battery types such as Ni/Cad.I deducted one star for the lack of an AC adapter. Be sure to use an adapter that can provide at least 2 amps at 5 volts.

Charger works well. I like the screen which shows battery percent, how long its been charging, and the voltage. You can also push the button to select between .5 A and 1.0 A to charge your batteries. Charges relatively quickly and works with my 18650s and 22650s. Basically it does what it says it does. It only comes with a USB cable so you'll need to get an adapter if you want to plug it in to the wall, but that's advertised so no points off.

Update: so I swapped usb wall plugs and cable and it works quite a bit better. It will charge completely but it's painfully slow and actually charges faster on .5 amp charge rate compared to 1.0 amp. So it's an okay backup chargerIt worked for a month or two. Now it doesn't charge. It displays that it's charging but my brown LG 18650s dont gain anything from this charger. My batteries are good because they charge in my other charger.It was cheap but I still expected more from it.
