Genius: best foldable USB chargers with built-in power banks for your iPhone or Android
On the other hand, every road warrior must have been convinced by now that enjoying the advertised wonders of an external battery pack to charge your phone on the go is not all that it's cracked up to be. You have to go out with your phone, a preferably portable power bank, the respective cable that fits your phone, and its wall charger, which may or may not be suitable for charging the external battery itself.
That's a pretty bummed setup, and far from the ads depicting happy people that whip out a power bank from their pocket when they run out of juice and simply plug their phones. Some power banks have built-in cables, but they are usually too short, and, besides, you still have to carry the bank's charger. Thankfully, enterprising manufacturers have been going a step above this solution by incorporating power bank-level capacities in USB wall chargers that aren't much larger than the default one that comes with your phone, and some of them even have foldable plugs for added convenience.
Thus, you only have to carry what you always carry with you when traveling with a phone - a power brick and a cable - but can also slip them in your jacket, purse or pocket for juicing up on the go. Most of those don't come with gigantic capacities, but are usually enough to add a full charge or two to many popular phones, and that's all we want when we are away from a wall outlet. Check some of those puppies out, and tell us if you have indeed found them convenient.
