Just right for the mobile office

I bought the machine, especially because you go always has the same dilemma: Where is the nearest outlet? As I also in the near future strengthened by the remote bus long distances will bridges in the home, instead of the car was the handle for this product almost mandatory.

Not to be dazzle you, however, by the power rating: 23Ah can be reached only at the fundamental voltage of 3.3V, so - logically - the amount of energy decreases with increasing voltage. However, I knew this before, including from the product page of this battery pack.

Very classy and in a good container of the battery pack arrived home, the latter perched on a slide, the pulling up and out and there finds all the accessories in the space, including various adapters for the DC mode and plug the USB spiral. But if you anyways bears his permanent staff at USB cables with them, the mediocre processed spiral cable does not need.

And do not forget the power adapter, and a small but rather enigmatic instructions, but with a bit of initiative reveals the following important items of information:

- As soon as you own an output source connecting (DC or USB) the corresponding icon appears on the display. Then, when the device connected to the battery pack, takes the power and eventually invites not charged device back on or bridged energy needs before the own device battery is charged

- To discharge the one also find the capacity display in percentage

- Choosing an appropriate output voltage happened on the Power On button: Press and hold until the output voltage flashes, then long press the Power On button until the correct voltage is selected and leave the battery pack while at rest until the indicator stops flashing: Finished!

What was not mentioned is that you should be careful that you do not fully discharge the battery pack: At the latest when it starts flashing on the display, you should remove the battery pack. But My experience was that the battery pack usually already at 2% remaining capacity from itself off. Furthermore, in my experience a simultaneous benefit of all output sources (DC and USB simultaneously) is not possible, but this also is not bad: Even the first MacBook Air had at least one USB port.

Recharging of the battery pack takes no less than 3 to 4 hours, if not longer, and is therefore perfectly acceptable. It can also simultaneously charge two devices via USB: The port comes with a 1A charging current, the second with 2.5A. The only problem that I had to realize in combination with my Galaxy Tab 10.1N is that the battery pack is not recognized as a power source and therefore seems to invite a maximum of 500mA, which the charging process of course infinitely protracted. Something similar could (!!!) and the iPad be the case, but I can not confirm that, because I have no Apple products in the house.

So what's left to say at the end? On a netbook, the battery pack doubles the capacity, of slightly more than 4 Ah (at 19V) the duration, further to the fully-charged laptop connects directly to the battery pack (which is also the most effective by far!). Moreover tolerate - contrary to the instructions - the battery pack and high currents, as I discovered on a larger 18 "Acer notebook and then give such mobile workstations to 3h longer term In addition, a common Smartphone recharging multiple times so again ... .it works, it's solid, it also looks chic. What more could you want?

A small tip but even in advance: A battery pack must be retracted. Otherwise it could happen that one time quite a "drop" gets to a, as he likes to be times consistently in lithium battery ... So from 50 to 10% because of me down. Therefore: Invite the battery pack on (if not already charged like mine), discharges it completely (ie no later than the display flashes) and upload it on again. That should make quite a few times, then the battery pack has its full capability. How good and long the battery pack will hold out is another story ... but if there which should unnecessary negative, I complete it gladly.

Otherwise: For the price ... unbeatable! And for the digital and at the same time mobile nomads of meaningful accessories that even relatively small makes an absolute buy recommendation in the backpack.
