Everyone hates running out of battery on their phone, no question about that, and carrying around an emergency battery charger is often a pain as they can be quite bulky, and external battery cases are just as cumbersome. But this charger is small enough to fit in your wallet.
At 7mm thin, the Proporta TurboCharger Pocket Power can juice up your smartphone or whatever gadget in your arsenal that takes a Micro USB jack, as well as Apple devices with an additional adapter. The Pocket Power tops up Samsung Galaxy S III devices by up to 23 per cent; the Kindle by 50 per cent and the iPhone 4S by 34 per cent. Perfect for juicing up your phone to make a few calls and send a few text messages when you’re in a pinch. The device packs a few LED lights to show you when you need to top up the battery too, and it doesn’t break the bank either at £12.95. Sorted. [ProPorta]

Alternatively – Spare Battery for my Galaxy nexus 5mm Thin. Charges the phone up to 100%
That’s always confused me; how come phone batteries can be significantly smaller be, well, 100% of a battery charge, yet you have to get something the size of a pack of cards to match that externally. surely they could just put the battery in a device that charges though?
Remember, the charging device has to have all sorts of circuitry that is normally contained inside the device you are charging to prevent overcharging/spikes/other nasty to batteries things. Also, the act of charging is not 100% efficient so less than the full charge will carry across to the device.
I accept a bit of circuitry, but to fully recharge my s2 from an external charger, the smallest feasible one I’ve seen is literally the same footprint, but at least 50% thicker. My phone’s managed to shove in a camera sensor, speaker, screen etc, you’d think there’d be more balance in the charging.
Amen to that.. Spare batteries, never leave home without them.
Do you swap the batteries around every day or something, or do you just have one battery that stays in your pocket for emergencies?
One great thing about my wee Xperia U is the battery can be pushed out to 2 full days with a decent amount of use
the screen’s not huge though, and no fricking sd card slot (not that I’ve needed it yet)/
I don’t use the spare battery on a regular work day as (like most) I have access to a wall socket.
But on weekends—
Spare battery pair : 10£
Not having to worry about running out of juice and getting lost (or bored or both) : Priceless
Normally I’ll swap them out daily, or thereabouts. Depends on usage tbh – atm a full battery will last me about 5 hrs because of the usage pattern, so if I use both of them in a day, I’ll charge both overnight.
5 hours? Jeez you must use your phone a lot, or it’s pretty beefed up!
Right now it’s running wifi-tethering so I can use a wifi keyboard app, so that generally eats the battery for breakfast, even though I’m not using the 3G connection.
If the screen is off and I’m just playing music, it’ll last probably 3x that, if not more!
Yeah that explains it! I was surprised actually at how little battery playing music actually takes; like it’s not doing much especially if you’ve got earphones in but I was still pleasantly surprised.
As long as the screen is off, then it’ll just sip at the battery
I actually have 2 spare batteries. a replacement standard battery for the nfc functionality and quasimodo, an extended battery with it’s own replacement back. I don’t generally carry them around day to day as I don’t need that much charge, but for specially occasions like Friday, where I was in London all day before the Gizmodo G+ meetup they are an absolute godsend.
Ah right, I guess you use it frequently enough to avoid degradation etc of the battery when it’s not in use
yeah I was just thinking like schoolkids going on DOE for a few days in the back end of nowhere must either need to keep their phone off or just carry a few batteries around with them. Ah how the times have changed!
Spare battery for my SGSIII, £19 from Amazon. Desk dock that will charge both phone and battery £15 from Mobile Fun. No brainer after buying a decent case.
You missed off “laughing as iPhone and HTC One X owners run out of charge – Priceless”
I thought that was implied
Lasted a 6hr day at a rugby tournament on Sat on one battery – the phone was mostly used for tweaking/cropping photos sent over wifi from my camera, then posting them online, all in bright sunshine, so maxing the display. Got home with 3% remaining, swapped batteries while in the shower and went out for the evening to a wedding reception to do the same again!
*Swapped batteries then went in the shower.
Doing what I wrote might have voided a few warranties….
Also according to what you wrote you apparently swapped batteries in the shower whilst at the wedding reception. Must have been a treat for the other guests.
Well there weren’t any complaints
Don’t ever buy one of these. I had one and it didn’t even charge it 3% before running out of juice on my 4S. If you want one, you can have mine
This is a brand-new product…
Notice the incredible similarities to the post a few months back:
http://www.gizmodo.co.uk/2012/05/credit-card-thin-battery-is-perfect-for-other-kinds-of-emergency-charges/
25% charge for iPhones, LED spotlight with the switch in exactly the same place, 7mm thick – looks to me like the same product with a different shell and a different lead.
Maybe you could buy one and let us know the results?
My apologies, they do seem to be different products with different size batteries.
Still, the one I had was “400mAh” compared to the 680 shown for this one. That’s not a massive increase in size and considering I got just 3% from mine it doesn’t inspire much confidence…
Perused the product page, and a wry smile crept over my face – for once the adapter is required to use an iOS device, rather than the other way around!
