Smart Battery Charger,Golisi I2 2A Universal Battery Charger with USB Port and LCD Display 2-Bay Speedy Intelligent Charger for Ni-MH Ni-Cd AA AAA Li-ion Rechargeable Batteries (Black)

This is my second battery charger designed to charge AAA, AA, C and 18650 batteries. I am well pleased with both and their use of a 5 volt USB connector for power. I am a solar enthusiast and power both chargers with solar panels located in my front bay window. Window placement is not ideal and the most I can generate from a 210 watt bank is about 65 watts. Still, the panels, like the USB chargers, meets my needs. I also have a couple of 150 watt panels on the roof for more substantial power needs.If you're interested in solar, either for emergency or augmented power, check out UGov.Net, American Home Emergency Preparedness. By the way, the digital readout provides for a more accurate readout than the three bar display on my other charger.I also recommend Gelosi 26650 4300 mAh batteries over other brands rated at or above 5000 mAh. I found the 5000 mAh batteries of a competitor were too large for my LED flashlight, which is compatible for 26650, 18650 and AAA batteries; the latter two are used with battery size adjustment inserts provided by the flashlight maker. Unlike the 5000 mAh batteries, the Gelosi 26650 batteries fit perfectly and ejected with only the force of gravity.

Wasn't very confident when I purchased this, but it matched my wants perfectly. Outside of the battery sliders being somewhat flimsy (but still feel like it will last long enough) and that off-gassing plastic/electronics smell, really pleased with this. Gauges are great and seem accurate for several different battery types, but I have no scientific proof

I bought this because my 21700 flat-top batteries needed to be jammed in to my old charger. This one, though it says it works for 21700 batteries had the same sized holder as the old one. This can cause problems when inserting or removing them, because it can cause the springs to snap back and cause them problems. The digital display is nice.

The official Golisi website said this was a counterfeit product. I scratched off the security code on the back to check the authenticity and entered it on the website. It said this product couldn’t be found. This product might be dangerous to use if it is a fake.

One of the best chargers I've used for 20700 batteries. What I like the MOST about this is that I can use a USB charger with this (car, portable battery bank, etc) and I'm not carrying around a clunky wall-wort.

Does charge, however when batteries placed on charger at the exact same time in 1A mode the left side charges almost double as quick would not recommend picking this up. If you look in the pictures I've posted they both been on for 20 minutes however the left side has charged 272 mAh and right only 140 mAh. No bueno.

Updated: turns out the scratches on the screen were just from the protective layer that I just now peeled off. Charger works great!

It seems pretty solidly built. I have had it a few weeks now and it works great. I like that it can charge different size batteries. The price is great too. I would buy it again.

This works excellently and charges my batteries much quicker than any of my mods do. Plus, it has safety cut off which none of my mods do - so it's a no-brainer really, unless you like firemen in your house.
