Waterproof Solar Power Bank 20000mAh with Compass
Never Watch Your Phone Die Miles From a Single Outlet
From a dead battery at the summit to two full charges in your pack — power that follows you anywhere the trail goes.
Engineered for the Worst Conditions
20000mAh of Real Backup
Enough charge for multiple phone refills across a three‑day trip. No rationing, no turning your phone off to squeeze out one last call. This is high‑density lithium that actually delivers the number printed on the case.
Charges Straight From the Sun
The front panel slowly replenishes the reserve while you hike. It’s not a main charger — it’s an emergency backstop for moments when there’s no outlet for days. Leave it face‑up in the sun and it quietly builds your safety net.
Waterproof and Drop-Tough
Matte casing with deep grip panels shrugs off rain, sand, and the inevitable drop on rock. Keep the port cover sealed and it’ll go through stream crossings and sudden downpours without a flicker.
Compass That’s Always There
No batteries, no calibration — just a magnetic needle set into the shell. When your phone is dead and you lose the trail, this gives you a basic bearing to the nearest ridgeline. It costs nothing to include and might save your night.
From the people who carry it
Two full phone charges over a 3‑day trip and still had one bar left. I’m not going without it again.
Kept my kids’ tablets alive on a 6‑hour off‑road drive. The dual ports are a lifesaver.
Bought it for the storm‑season go‑bag. I tested it in the sink — bone dry inside. Peace of mind.
Survived a weekend of beach sand and a surprise wave with zero issues. Solar charging is slow — I use it as a top‑up, not a main charge.
The carry loop is genius. Clips right to my pack daisy chain. LED gauge is easy to read.
Tossed it in the boat all season — still going strong. The compass is a nice touch for quick bearings.
Charged my phone and earbuds on a cross‑country drive. A bit heavier than my old slim bank, but I knew that going in.
Solid build, feels like it could survive a drop off a cliff. Compass works great as a backup.
Lasted the whole music festival through dust and rain. My friends were all borrowing it.

Everything You Get
From Battery Anxiety to Worry-Free Adventures
Every off-grid trip used to start with a tight chest — how long until the phone dies and the trail goes dark? This is how we fixed that.
The 3% Moment
You know the feeling. Miles left to go, no signal, and the battery icon flashes red. GPS is gone. Your camera is gone. In an emergency, you’re one beep from a walkie-talkie. That moment replays in your mind every time you zip up the pack.
Power That Follows You
A single brick that gives your phone multiple lives and pulls extra juice straight from the sun. Throw it in your pack, clip it on the outside, and forget about rationing. Two USB ports mean a friend charges too, and the compass is always there if the phone really does die.
Pack It and Forget It
Now every trip starts with a full phone and zero anxiety. You snap your photos, follow your GPS, and know a backup exists even when there’s nothing but trees and sky. Power stops being the thing you worry about so you can focus on the reason you’re out there.
