It's a fair cop, my title was more descriptive than accurate - this little gadget is actually called, on Amazon, the 'EC Technology 5200mAh Portable Charger External Battery Power Bank', a typical SEO-heavy name that's not as interesting as the product itself. You see, this fills a very real need, at least in my household.

The flow of really rather handy emergency chargers into AAWP Towers never seems to stop. I couldn't resist taking a look at this one, since it promises metal (which I like), very high capacity (ditto) and compact size (ditto again). And it delivers, you can charge two smartphones at a time (e.g.) at 1.5A each, several times over from scratch. All from something that fits in a jeans back pocket...
The search has been on for several years for a replacement for the (now no longer produced) Proporta Pocket Power, an all in one, no cables needed, truly credit card sized emergency charger - and, right up at the premium end of the market we now have a candidate, offering full 2A output and able to deliver around 700mAh at 5V in about 20 minutes. While only around a one third charge for today's smartphones, that this fits unobtrusively in your wallet in a card slot makes this a terrific (if slightly pricey) accessory to get you to the end of a long day. Coming in deluxe packaging, with extras, it's also just about the perfect gift for a smartphone owner, as I explore below.
Even if you do the usual 3.7V/5V maths to calculate the actual power available at the voltage your smartphone needs it (i.e. the 5V level), you still end up with well over 15,000mAh of useable charge from this new 'Executive' power bank. Add in a unique backlit LED readout, triple output jacks and a torch function and you've got a really, really interesting mobile accessory.
Guest writer David Addington brings us a detailed review of one of the landmark texts in the smartphone industry and a superbly detailed history of Symbian itself. Read the review and then grab the (e)book!
After reviewing quite a number of emergency power banks on these sites, most of which have been quite impressive, I think we have a brand new winner. In terms of build quality, output, capacity and sheer value, the Omaker Premium 15600 wins out over the rest of the competition by a clear margin. As you'll see from my illustrated review below, testing the Omaker with Symbian and Windows Phone smartphones, plus an iPad or two...
Another in Lumsing's excellent series of 'Power Banks', the 6000mAh model here is distinguished from its larger 10400mAh sister by being dramatically slimmer and almost all metal. As a result, the price-per-milliAmp-hour is higher, but I don't care - the 6000 is a "man's" charger - a veritable mobile power tool and yes, you can knock nails in with it. Probably.
Originally an Indiegogo project, Shoulderpod has just released its first product, the S1, and I've been testing it with my Nokia 808 and Lumia 1020. It's a combined stabiliser/grip/mount - it's fabulously constructed and it works really well. Here's to better smartphone-shot video (and, of course, you might find my tutorial helpful!)
The concept of a portable power bank/emergency charger isn't new, of course, especially in these days of smartphones with sealed batteries, for which the only emergency option is usually to plug something in via microUSB. The Lumsing 10400mAh option is new and reviewed here - build quality is excellent and - I contend - the value for money utterly unrivalled.
Regular readers will know that I'm a big fan of the Proporta emergency chargers, from the tiny credit card sized Pocket Power to the mighty Turbocharger 7000. But, of course, there are many other brands on the market, especially at the higher capacity end of the market. Which is why I've been taking a look here at the new 'Kinkoo Infinite One 8000mAh Portable Backup Battery Charger'. In white. And yes, the colour matters, as I shall explain!
