Works great, and came with a 5v 2a charger!
Your browser does not support HTML5 video. This product had only 1 other review, and that person gave it 1 star saying the device took him over 24 hours to charge a battery.I suspect that person has little to no technical know-how.I'm a Lead Systems Engineer/Chief Technology Officer for a large (150+ employees) company, and I just received this gem today for the low price of only $5.99!I figured at that price, if it was DOA, I'd send it back and get a refund.So far this device is performing better than expected.It came with a 5 volt 2 amp charger, and USB to EIAJ power connector.The device has only 3 yellow leds to indicate charging/charged status (rapid, alternating of "top" two leds indicate charging [battery low], only the "top" led flashes rapidly when charging [battery is between 50-99% {assuming approx. level}], and all 3 leds are solid yellow when fully charged.There is also a solid blue led in the upper right-hand corner that is always lit up (I'm assuming that's to signify that the device is powered and ready to charge batteries?).My last charger was a BONUSIS HXY-H1 which had a fancy LCD display that showed voltage, amperage, and current while charging a single 18650 batter, and while this new charger has no such display, I am very pleased with it for the price.I would definitely recommend this product.FYI, I'm using the following batteries on it for my Box Mod Vapes:LG ICR 18650 HD2 High Drain Li-ion 3.7V 2000mAh 25A Rechargeable Flat Top Battery, (2 Pack) by M&A BD ElectronicsThey were sold to me by Amazon, but while trying to post the link, I noticed that it's 404'd now...https://www.amazon.com/gp/product/B07DTKH98C/FYI, gave it 4/5 because having a display with more information kinda spoiled me.Device is really 5/5 (so far [only owned it a few hours])//Update 09-14-2018Was going to purchase another one for Home, but they bumped up the price to $10.99Even at that price it's a good buy, but...

Good value
Got this to charge surveillance camera batteries, which drain in about 24-36 hours. Charges up the batteries quick. Indicator lights are helpful but very bright.
