It’s well known that the iPhone battery life leaves somewhat to be desired and while I have heard that Apple have done a bit better with the 3GS, with the amount of usage a typical iPhone gets, it will always be at a premium. Yes, there are some things that you can do to improve the battery life on your iPhone (like turning off Wireless and Bluetooth when not in use), but generally there’s no substitute for having a charger with you all the time.
Of course a charger is only useful if you have a wall socket to plug it into, and for those of us who travel a fair bit, sometimes it’s hard to find enough places to charge your phone. This is an issue for those who spend a great deal of time in remote areas, or on outdoor adventures (bush walking, camping, dive trips) as well.
Once again, I’m happy to report that Proporta.com have come to the rescue with the USB Turbocharger 3400. I’ve been playing with this gizmo for a couple of weeks now and it’s pretty cool. Essentially it’s an battery pack, shaped like a very small external hard drive which comes with several different connection pieces that allow you to charge, not only your iPhone but most modern cameras, iPods, and other USB powered devices.
The first thing I noticed when unpacking the battery was that it’s extremely light. The pack that it comes in includes a small bag which keeps the battery and the various connectors all together when traveling.
The charger itself is equipped with a standard USB port for charging itself (this is done by connecting the device to your computer directly and generally takes 3-4 hours) and a mini USB port which acts as the outlet charge port. A bank of Leds on the device allow you to see the current level of the battery and also to see the progress of the charging process.
The kit comes with a retractable cable and a range of interchangeable connector heads including 1 x DS Lite, 1 x iPod, 1 x Nokia, 1 x Sony Ericsson, 1 x Micro USB and 1 x Mini USB. A PSP connector is also available from Proporta on request.
Other reviews of this device that I’ve read have reported that 7-8 charges are possible from a single charge of the mobile battery, but I guess this will very somewhat depending on the size of the battery in the device that you are charging. With my iPhone I have found I can get 3-4 charges out of a single charge of the main (mobile) battery which would typically keep me going for 7-10 days, more than enough for most trips on the road.
In the end I have to say that this little gadget is extremely handy to have on hand for those trips where you may not have the luxury of plugging your phone into a power point every couple of days, but where you still need your phone or other device to remain charged and at approximately AUS$50 (excluding delivery) it’s quite conveniently priced.
