There is nothing worse than having a mobile phone run out of power and you're nowhere next to a plug socket. This occurs to me quite a lot while I'm having particularly hard-working days thus I was extremely happy as Mobile Fun asked if I'd like to take a look at the backup usb power bank.
The tool itself is around the size of a portable hard drive that is so easy enough to keep in a bag or carry in a coat pocket and isn't particularly heavy. I was able to go out for the day with it tucked inside my coat pocket and didn't notice I'd got it with me. In addition, I was cheerful I'd got with me by the time I'd got to the pub at the end of the day as my phone was on its last legs.
It comes with a usual micro USB cable and an iPhone specific cable. It also is on the front, which is a status LED and a press button. All you have to do to get it running is connecting the tool and press the switch. Nice and simple! The charger has three ports, two are outputs and the other one is for actually charging the battery via USB.
Charging is pretty quick when connecting to the mains but it worked equally well while connected to a PC. The curly cable is useful as it helps to keep the bulk down, however, without sacrificing the length of the cable, it doesn't work.
The instructions included indicated the 8000mah usb power bank, which should be operated for charging larger devices such as an iPad with the other port for phones. I couldn't make my mobile to charge with the 1A port but it was in the other port.
The instructions also indicate us the 6600mAh 3.1 Amp battery can charge a smart phone approximately 4 times and a iPad up to 80% in addition to holding it's charge for up to 90 days. On the contrary, bold claims that, my experiences so far have been very pleasant. I've operated the charger to breathe life into my phone as well as my Kindle.
Not much more to say. It does precisely to tell you where to buy power bank, because there are variety of the online shops. I took with me on a tour to Dublin recently and it was great knowing I wouldn't have to worry about running my phone down, which happens all too easily when taking photos, looking for directions and general browsing when doing the tourist thing.
This particular device is ￡39.95 but having made full use of it lately, so I think it's worthy. There are plenty of alternatives in several sizes and prices, but for my usage, this is a good fit.
