In itself a good thing, especially if you're a long way and his phone has often used it to quickly write an email or you phone a lot.
But now the rub: The charger needs a mile long until it is charged to the PC. Even after 4 hours of my portable battery was not charged. During this time I had my cell phone with the regular charging cable can recharge.
Furthermore, the charger is very compact and difficult, which in turn complicates the use of cell phones while Aufladphase.
Moreover, Sony promises that the battery device up to 3 times the phone is charging fully, whose is not the case already after half boots I had to re-connect to my PC the device.
Actually a good thing, but on the other hand, over-priced and too unwieldy, as I could issue a strong buy recommendation.
In an emergency, certainly a useful device but nothing more.
Do not quite know what to make of.
Positives:
+ Loads the usual phone quickly
+ Could be in an emergency of great benefit
+ For short trips more than adequate (although you can just as well take his charger)
+ Easy application
Negatives:
-To Hard and compact
- Does ellenlang to charge on Pc
- Loads definitely not 3 times an empty battery
Conclusion:
Who uses his smartphone often could be well served with this!
A really positive benefits I can not honestly see here.
