Review on XTAR 4-Bay Rechargeable Battery Charger for 3.6V 3.7V Li-ion IMR INR ICR 10440 18650 26650 & 1.2V Ni-MH Ni-CD Batteries - Optimized for Efficient Charging by Colleen Guaydacan

It's no secret that this is a cheaper charger, although a question; Is it worth it? And this answer is absolute. It offers 1 amp charging on the two outermost slots and 0.5 amp charging on the middle two. One of the downsides I have with this unit is that if there are batteries in the middle two slots, the 1 amp charge will change to 0.5 even if the other batteries are fully charged. So if you want true 1 amp charging, you can use a maximum of two batteries at a time. Bummer but not a game changer and once you figure out the location of the battery, charging is very fast (nearly 3x faster than my previous Nitecore charger). The smart aspect of the device is great: when the battery is almost full, the charging process is drastically slowed down for the last 100 mAh to avoid overcharging, which could affect the future charging potential of the battery. The display is great and pops up better. than any other block I've ever seen. It has a nice blue tint that really lets the display shine and isn't too dark. Speaking of the display, it unfortunately only shows information for two slots at a time, which can be scrolled through with the press of a button, but there's enough information. It shows the current state of charge of your battery (shows voltage instead of percent, but basically works the same) and how much charge has been added to the battery since charging started in real time. My final note is that this does not come with a power adapter, just a USB cable. So you will need at least a 2 amp power supply to take full advantage of this charger. Luckily I had an extra one that came with my phone, but many people can buy it without. And while you can still plug it into any USB port without a wall adapter, you'll get significantly slower charging speeds. TL; DR: An excellent fast charger with a stunning display that has few issues. If this was a much more expensive item I would deduct a star for the few issues I have, but considering I paid $16 for this item it was worth every penny and more.
