Jackery Air is a portable USB charger that is actually useful!
If you’re like me you have several USB chargers lying around. Some of them I got for free at events, some I paid over $100 for. All of them are mostly useless though because they all slowly leach their charges out so that by the time you need them, they are dead.
The Jackery is different though, it has an advanced power lock technology that allows it to hold a charge for six months in standby mode! That means if it’s in your backpack or locker at the gym it won’t be dead when you finally need it.
And it’s small and nicely designed to boot :)
$49 get’s you the battery pack with the 6 month charge protection!
