This power pack is heavier than most, but it packs a wallop. Its probably not something one might carry in a purse or a travel bag, but is great for a permanent spot in a car's glove compartment or stowed-away in checked baggage for use on the other side of a plane ride.
The AUKEY 20000mAh 3.4A Dual USB Lightning power pack is a monster. The 20000Ah battery gives you the ability to charge a smartphone four or more times and the included Quick Charge 3.0 capability means it charges devices much quicker than other portable power packs.
