I use a lot of batteries testing lights, so I usually have a bank of 3-4 chargers plugged in at all times, with a lot of cord clutter and wasted space. When I saw this charger for the first time, I knew I needed to have one, as long as it was a good charger. I thouroughly examined HKJ's review, and it looks like this charger delivers! The large charge bays means that this can charge up to (8) 26650s concurrently--something that most 4x or more chargers can't do due to the larger diameter cells. This charger works with cells up to 72mm long, accomodating even the longest protected cells and 26700s, with a positive pole connector that works with both flat top and button top cells.
The ALL-80 is like a megasized Nitecore i4, except it actually charges almost twice as fast as the i4 with 4 cells in it, since each channel has an independent charge current of 650mA, compared to the i4 which shares 750mA between two slots, which only gives 375mA with more than one cell in that channel. Like the i4, the ALL-80 can also charge NiMH cells automatically--even alongside Li-Ion cells!
