Proporta’s USB Mobile Device Charger: extra power for small devices



For $45, the Proporta USB Mobile Device Charger looks well worth the purchase price if Arne’s review is any indication. The unit houses a 3400 mAh rechargeable battery that can be juiced up through the USB port of a laptop or desktop. When you’re not charging the internal battery, you can use the stored power to extend the battery run-time of mobile phones from Sony Ericsson or Nokia, plus if you’ve got a device that charges via a mini-USB cable, you can power that too. Just about every HTC phone I can think of uses this method, so that option is particularly appealing to me. Tipping the scales at just 120 grams and measuring just 100 x 62 x 15 mm, this is light enough to carry around all day.



These battery packs are cheap on eBay. Usually marketed for the PSP though. I use mine with my WL-HDD, PSP, XDA Mini, etc… Very useful.


It’s a bit pointless for Sony Ericsson users though since the factory data transfer USB cable also charges the phone


hi lorie. i’m wondering if you can tell me how many additional hours do you get with the MP3400 and does it come with the correct adapter tip connecter?
