We are very far from the listed capacity, the cells used are Chinese and not Japanese (block opening), the capacity of each cell is less than 2000mAh, 3 in parallel, it can not therefore be 6600mAh .. After loading a block of three cells, the ability of it is 5000mAh (4996mAh exactly), in short go your way or knowingly buy, not expensive, but it is far off, and Chinese cells have a short life (for SZN in particular, herein).
