Looking to get juiced?
Don't get fooled by the name Jackery Giant. This little USB charger fits in your pocket (as long as you're not wearing skinny jeans - RICK!) and can fully charge an iPad Air or charge an iPhone 6 four times before it has to be recharged. Have two devices that are dying Romeo and Juliet style? No problem, this thing has two USB ports, so you can charge both devices at the same time.
The 12,000mAh lithium ion battery inside is a beast of technical engineering and can be charged over 500 times. The only possible way this could be done is by a combination of advanced battery technology and Grandpa-magic. Charge this thing up once, throw it in a bag, and you'll never be caught without power again. Oh, and it's under $35.
