Another year, another design iteration of Proporta's bestselling mobile charger range. This is 2009 and we now have the USB TurboCharger 1200 and the USB TurboCharger 3400, with the numbers helpfully telling us how many mAh of charge are stored within. I've been reviewing the (physically and electrically) smaller version - is it worth sacrificing charge for size?
Read on in the full article.
I have the Proporta USB Mobile Device Charger and after a year and something the usb output doesn't make correct contact and you must not move it even a milimeter when you find the right place! I hope they fixed such problems here!!
What's the point - a Power Chimp is two quid on ebay and will charge any phone from an AA battery. Yes I know it won't charge it much from one battery, but it's much smaller to carry, and AA batteries are small and as cheap as chips and always available, e.g. when you're hiking and can't get to mains or a PC. You can even shove it in the phone and leaving it hanging out of the bottom if you get 'low battery' during a call!
@ The poster above:
Because the method you mention above doesnt really 'charge' the battery. It just supplies 'life support for it'. You will need at least 3 duracell batteries to get anything close to decent (on more power hungry phones aka N95, not sure about the simpler models)
@Faiz
Yes I think that's right - but it's still a useful facility when the phone is on, and it will charge it when the phone is off, i.e. after it turns off because the battery is dead, or switched off overnight (which is my normal use case).
I remember the old days when phones used to sit on desks in a deskstand that had a slot to charge up a spare battery. I haven't had a battery drop more than a couple of bars in years now. Good battery husbandry is not difficult and has many benefits.
