The battery pack has the following dimensions: 7.0 x 5.3 x 2.2 cm
The weight of the battery pack is exactly 120 g
Supplied with the Just Mobile Gum PRO Mobile Power Pack 440 includes the battery pack, a USB cable (USB to mini USB) and a Quick Start Guide.
The designation 440 in the product name stands for the 4400 mAh capacity.
On battery pack itself, there is a switch for "on / off", 3 LEDs, a mini USB and a USB port.
The Mini USB connector the battery pack is charged, either directly through a USB port on the PC or via a suitable power supply, via the USB port power is delivered so that a USB charging cable smartphones, iPhones, Nintendo DS, Navigationsgeäte, etc. with electricity can be supplied.
In charge of the battery the switch to "Off" position when you want to invite his device, you can switch to "ON".

By comparison with an iPhone 3G:
A fully charged Just Mobile Gum PRO Mobile Power Pack 440 is an empty iPhone 3G times completely recharge 2.5-3, here the iPhone was on there and 3G and WiFi enabled. If you switch from this, as a higher power of the battery pack would be possible.
As written above, NDS and other devices can be charged, but there is a small feature that means half a star deduction for me:
When benefits of a Navigon 7210 or 7310 a small blemish is given, invites you to be Navigon only, so there is no Einscränkungen, everything works without problems, but you want to extend the useful life of its Navigon in operation, so it does not work because the Navigon immediately switches to the USB / PC operating in operation.
I can not judge how this looks in similar devices.
But since this is only a small blemish and the Just Mobile Gum PRO Mobile Power Pack 440 full power provides full and intense life offers the user, I forgive 4.5 stars, which is rounded up to 5.
Strong buy recommendation, especially since this Just Mobile Gum PRO Mobile Power Pack 440 can not be used specifically for a device just by pointing out that the mobile phone manufacturers have agreed to an imminent and unified USB charging, so that in future problems all mobile phones can charge herewith.
