After unpacking, we are pleasantly surprised at the size and weight of the case: used lead batteries, I was expecting a "craft" the size and bulk of a motorcycle battery! The LiPo technology changes the game and we get a box that fits in a pocket or in a corner of the document holder. An essential backup power for a maximum of autonomy with all modern equipment, the battery does not hold the week (large touch screens is voracious!). The cables supplied are interesting, and are used to connect the most common devices (except Apple), but if you have the USB cable that comes with it, do not worry ... Two "light" negative details to clarify, not to the detriment of the product but must be assessed for the proper use of this type of product: We would have liked comes with a mains charger or cigarette lighter, but these accessories are not necessary, and often has several copies. Charging is done anyway on any PC or USB power! But to reload this power quickly, it is advisable to have a USB power supply providing 1 amp, or a laptop with a socket for fast charging (I have an Asus who does ...) with a capacity of 14 Ah, we need about 2 days to make a full charge with a "small" power or PC standard USB plug which provides only 500 mA. Spiral cords provided are certainly very practical, but the quality (cable section, adapter cards) seems to be able to slight "pass" currents of 2 A for several hours without heating: there is in this case preferable to use cords original. But the USB standard is originally limited to 500 mA, few devices navérerons as "greedy"
