Let’s start off by covering the basics, dimensions and weight. These two parameters can be vital if you spend a lot of time on the road, or tend to pack a lot of gear in your backpack. The PowerPack 12000 weighs 258g, but thanks to its exceptional battery capacity, our mobile phone and satnav could operate for several days without a socket. Pretty impressive for a device which weighs less than a 7-inch tablet.

You might not fall in love with it at first sight, but as time goes by you are bound to appreciate the simple and clever design. The PowerPack 12000 features a square design, with curved edges, which makes it is pretty comfortable to carry around in a pocket. It measures 99 mm x 93 mm x 29 mm (L x H x W), so it feels like an oversized wallet, not much bigger than a compact camera. Basically you can even fit it in small coat pockets, or just about anywhere else.

The PowerPack 12000 features a closed-form factory design and that means you cannot access its insides, but there is no need because all connectors are easy accessible and placed on the sides. It features a Li-polymer battery with a capacity of 12000mAh@ 3.7V (44Wh).

Once your PowerPack dies all you can do is buy a new one, you can’t replace the battery. The problem with rechargeable batteries is that they have limited lifecycle. TGT claims the battery can stand up to 500 cycles, which should be enough for most users. For example, if it’s charged once a week, it could last for up to ten years and that’s plenty. Sadly though, it ships with a one-year warranty. In order to prolong its life, discharge and recharge the power pack periodically if you don’t plan to use it for an extended period of time.

The PowerPack 12000 is more stable if we place it horizontally on the table, as show on the image above.  Small, rubber pins are placed on each corner (see image below) and to prevent scratching.

The rubberized surface feels great. When you hold it in hands you get the feeling you are dealing with a very robust piece of kit, and since it has a rubberized finish, it should also stand up to punishment quite well. The silver bit in the middle and the clever design of the power button with included LEDs are additional highlights. Frankly it seems a bit over-designed, which is a good thing.      

On the next image we compare it to a standard 7mm SSD drive. As you can see, it is not really a flat device, but it is small enough to handle in any situation and it doesn’t take up too much room.
