This is ChargeAll, and it claims to be the world's first and smallest portable battery pack to have an AC power outlet built-in. Unlike traditional backup batteries, this one features a full sized AC power outlet in addition to a regular old USB charging port. Available in two capacities: one with a 12,000mAh internal rechargeable lithium battery and a larger ChargeAll battery (still portable) with a 18,000mAh capacity capable of recharging any device that requires up to 85W of power like a MacBook Pro. In fact, the people behind the ChargeAll battery say that its 12,000mAh portable battery can fully recharge a MacBook Pro two times over, while the larger battery can triple that amount which sounds like an impressive claim to fame to say the least.
