Poseidon Pro - 10200 mAh, 37.74Wh

The Dark Energy Poseidon Pro is built for the trips where a standard power bank would be a liability: the ones that involve rain, river crossings, or a hard drop onto granite. Drop protection and IP68 submersion rating mean it survives the moments that kill ordinary electronics. The built-in voltage regulator and surge protection keep whatever's plugged in safe at the other end.

What Our Gearhead® Experts Are Saying:

"I keep this clipped to my pack on river trips because a dunking at the put-in doesn't end the day. It stays sealed to six feet for 45 minutes and still has enough capacity to top off my phone two or three times before camp."
