I bought this mainly for holidays and business trips where there tend to be lots of different devices taken, mobile phones, mp3s, Sat Navs ... all with different chargers ... so this little unit can save a lot of weight and bulk.
The unit comes fully charged from the factory which is a pleasant surprise, and has enough adapters to meet the majority of people's needs ... eg I need a micro usb for my phone, my wife needs a mini usb ... both need ipod, and camera uses another tip.
The set is supplied in a hard plastic case that given a bit of thought could have been used as a travel case ... however there is a small neoprene case for the charger and there is just about enough room for the retractable charging lead and a couple of tips.
The unit itself is charged from a usb socket and the retractable lead is reversed for that purpose. I have paired this up with Veho's own usb international usb charger, and it works great.
Fully charged we got 4 good charges for our phone and a top up on the sat nav before the unit itself needed to be recharged. there are 4 blue LED lights that show level of charge.
We found that the Veho unit needs a good overnight charge to fully top it up from empty, and then it is ready to go again. We have not really noticed any appreciable drain in power if it is left for a few weeks, and so far so good.
Pros are that you can leave most of your charging gear at home, and will top up 4 or even 5 times before it runs flat ... only real con is the case ... could have been thought out a bit better
