Name the traits you want in your standalone portable charging station. Slim and lightweight, yet durable and shock-resistant? Check, check, check, and check. What about waterproof or hugely powerful? The Kodiak Plus has 10,000 milliamps of power that will fully charge your tablet, phone, bike light, or whatever else you plug into its dual USB outputs. An ideal outdoor adventure accessory, it can stand being submerged in water up to three feet for almost half an hour. Charge it at home, then leave the cable on your desk. You won't be needing that anytime soon.
