- excellent capacity; using it with SKU 36086 it took more than 6 hours to bring the battery down; - excellent build quality and packaging, showing great care of the manufacturer in presenting a high finishing quality in this product; - handy pouch to keep everything together and safe, as it is made of a somewhat soft material; - several plugs available, many possibilities; - four output voltage levels: 4.8 , 5.8 , 8.4 and 9V, many more possibilities ;-) ; - there is a quite bright handy LED, enough to find your way around or some lost thing in dark places; - three ways of recharging: solar, USB and mains. - and it is beautiful, with elegance and discretion;
There is no way of knowing the charge/discharge rate and battery capacity left, and it takes a long time to recharge, even using USB or mains. Perhaps this saves the batteries from stress, though.
Perhaps a simple LCD display showing the percentage of charge left on the batteries would improve a lot its daily use.
Very good product at a reasonable price.
