At the product level, it is packed in a cardboard box. It contains: external battery, a manual and a charging cable. Everything is arranged in a plastic box that can be storage box office. The battery is well protected inside, thanks to the presence of a protective foam.
The battery is pre-charged to 80%. to load is simple, plug there on a USB port on your computer (Attention, long loading!) or to a wall outlet (Count 8H to fully charge). I used my Nexus 4 adapter for charging the battery. Perfect! Loading is fast. An LED indicates the battery level (red, blue, white ...) Another LED indicates the unit is on. Diodes are bright, can upset some people, and you decide to charge your battery overnight! The charging my laptop is quick. No worries at this level. I did not try with tablet.
The battery design is successful. The surface of the battery is non-slip. For those who has put the battery in their pocket, do not think about, it is relatively heavy.
The document is in several languages, including French, but this is the literal translation. That is to say that it's a little chopped as an explanation. The notice is nevertheless understandable. The only downside to this product is the cable length, to recharge the battery. It is too short. We are obliged to allow the battery to the ground, which is a shame!
The product remains good, especially at the price. I recommend!
