To purchase a Dark Energy Poseidon ruggedized device charger for 10% off MSRP, use code "TWGnBG10" at the following link: http://www.amazon.com/dp/B016DUBSJM
The Poseidon is the first patented device charger with an IP68 rating, which is the highest possible rating for dust and water ingress. It also has been independently tested for drop impacts according to MIL-STD-810G.
What it can charge: - smartphone 3-6x (I got three full charges for my iPhone 6) - two-way radio 4-8x - GPS 3-5x - tablet 1-3x (I got one full charge for my iPad Air 2) - bluetooth speaker 4-7x - trail cam 4-5x - rangefinder 6-8x
I take two Poseidons and put them through a few of my own tests, showing that this device charger exceeds Dark Energy's claims, and then some.
