Generate Fire, Light, Electricity & Signal Anywhere - Even During Complete Blackouts

When the grid goes down for days, when you're miles deep in a forest with no outlet in sight, or when a storm leaves you stranded with no battery - most people are stuck with nothing.

PowerTank hands you everything in 1 device: turn the crank and you've got a flame to start a fire, a beam to light the dark, real power to charge your phone, and SW/FM radio to stay on top of emergency broadcasts.

check holds a charge in reserve - crank now, draw power later when you actually need it

Power That Never Runs Out - Day 1, Day 3, or Day 30

Most backup plans die fast.

Batteries drain, power banks empty, and generators are useless the second fuel runs dry.

GridZero never hits empty. As long as your arm can turn the crank, you've got power - no fuel to stockpile, no battery to outlive, no limit on how long it lasts. The crisis can drag on for weeks. Your power source won't ever quit.

check requires zero maintenance

Stay Connected When Every Cell Tower Goes Dark

In a real disaster, cell towers are some of the first things to fail - and the moment they do, your phone becomes a useless brick. That's when the people who stay informed are the ones with a radio.

PowerTank's built-in SW/FM receiver pulls emergency broadcasts, weather alerts, and news straight from the air - no signal bars, no service, no network required. While everyone else is guessing what's happening, you'll know.

check shortwave reaches signals from hundreds of miles away - not just local stations

    GridZero™ PRO vs Powerbank vs Big Generators

    Powerbanks die when they're drained. Generators die when the fuel runs out - and in an emergency, fuel disappears fast. PowerTank never runs empty: no charge to lose, no fuel to find, just power for as long as you can turn the crank.

    Easy to use

    counter_1
    Crank it up

    Just turn the hand crank for a couple of minutes. That's it - no outlet, no batteries, no fuel. The motion alone builds real, usable power inside the device.

    counter_2
    Power what you need

    Plug in your phone, switch on the light, spark the lighter, or tune the SW/FM radio. Use one at a time or rely on whichever you need most in the moment.

    counter_3
    Store the reserve

    Cranked more than you needed? The extra power stays banked inside, ready to draw on later - so you're never caught starting from zero when it counts.

    What our customers think

    • Fantastic

      storm took out our power for almost 4 days last winter and this thing was honestly a lifesaver. kept my phone alive enough to check on my mom and the radio is how we knew when the roads reopened. crank is a little stiff at first but you get used to it. wish i bought one years ago.

      Cole S.

    • Very happy.

      Got this mostly for road trips and breakdowns, keep it in the glovebox. Ended up using the light way more than I expected lol. The fact that it just works without needing to charge it first is the whole point for me - no batteries to find dead when you finally need it.

    • Surprisingly good

      gotta be honest, I thought it was gonna be one of those gimmicky things that barely works. It's not. Cranked it for a few minutes and it actually charged my phone - not super fast, but it works. The lighter feature was a nice surprise too. Solid little thing to have around.

    • Super!

      Works great, no complaints really. Only thing is you do have to crank a decent bit to get a full phone charge, so don't expect magic. But for emergencies that's not really the point, is it. Radio comes in clear. Shipping took like 9 days but whatever, worth the wait.

    • Excellent overall

      bought this for my husband and now he wont stop showing it to everyone who comes over 😂 he keeps it by his hunting gear. honestly i think its great too, used the flashlight part during a power flicker last week and it was right there ready to go. happy wife happy life i guess!!

    • Unbelievable value

      does what it says. crank works, light is bright, radio picks up local stations fine. havent tried it in an actual emergency yet thank god lol but feels well made. only thing id say is read the instructions first, took me a sec to figure out the modes
