Check the specs before you buy.
Many solar power banks list inflated capacity. Gridless lists its real rating: 37Wh, about 2 to 2.5 full phone charges.
60-Day Money-Back Guarantee
We're sure you'll want to keep it. If you're not happy, send it back within 60 days for a full refund, no questions asked.
Built For Storm Season, Not the Shelf.
2–2.5 Phone Charges
The 37Wh battery gives most phones about two full charges. A phone on battery saver checking storm updates stretches it further than one streaming video.
Charge counts vary by device and usage.
3 Devices at Once
USB-C, USB-A and the wireless pad all work at the same time, so your phone, your partner's phone and a radio or flashlight can charge together.
20W fast charging on the USB-C port.
The Sun Is Your Backup Plan.
-
Charge It From the Wall First.
Plug it in before the storm, not during it. A full wall charge is the main charge, and it's what gets your phone through the outage.
-
Stash It In Your Kit or Drawer.
Clip it to a go-bag, drop it in the kitchen drawer, leave one in the car. Charged and waiting is the whole point.
-
Let Direct Sunlight Top It Back Up.
When the outlets are out, lay the solar face in direct sunlight. Solar is the backup top-up, not the main charge, and it needs real sun, not a cloudy windowsill.
★★★★★
Pro Tip
"Top it off from the wall once a month so it's always full when you need it. If an outage runs long, direct sun keeps it going."
Be ReadyBefore the LightsGo Out.
When the grid fails, your phone is your lifeline. The only question is whether it's charged.
Drag the slider to see the difference
"Charge it before the storm. Keep it in the drawer. Stay reachable when the lights go out."

If it doesn't earn a spot in your go-bag, send it back within 60 days and we'll refund your purchase. No questions asked.

Your Questions, Answered.
Does it really charge from the sun?
Yes, but think of solar as your backup plan, not your main plug. Charge it from the wall first so it leaves the house full, then let the panel top it back up when the outlets are out. Solar is a slow top-up and needs direct sunlight.
How many times can it fully charge my phone?
About 2 to 2.5 full charges for most phones. Exact counts depend on your device and how you use it.
How fast does it charge my phone?
The USB-C port delivers 20W fast charging. The USB-A port and the wireless pad are slower but fine for overnight charging.
Is it waterproof?
It's IPX4 splash resistant, not waterproof. Rain, splashes and a damp go-bag are fine. Keep it out of standing water.
Can I take it on a plane?
Yes. At 37Wh it's well under the TSA's 100Wh limit for battery packs. Pack it in your carry-on, never your checked bag.
What if it's not for me?
Send it back within 60 days for a full refund.
