OSTNER® Emergency Solar Power Bank
OSTNER® Emergency Solar Power Bank
The grid fails on its own schedule. This doesn't.
A 10,000mAh emergency power bank that recharges four different ways — including from the sun — throws light in two directions, and shrugs off rain, dust and a drop off the tailgate. It lives in the go-bag, the glovebox or the kitchen drawer, and it is ready the day you actually need it.

Straight talk about the solar panel
The panel is there so the unit never sits dead in a drawer. Left on a sunny windowsill or clipped to a pack, it trickles the battery back up over a matter of days — that is what an integrated panel this size does. It is a maintenance and last-resort feature, not a replacement for a wall outlet. Anyone telling you a pocket panel refills 10,000mAh in an afternoon is selling you something. Charge it from USB-C before you need it; let the sun keep it there.

Frequently asked questions
How many times will it charge my phone?
About two full charges for a typical modern smartphone. Capacity is rated at 10,000mAh (37Wh); real-world output is lower than the raw number because of voltage conversion, which is true of every power bank on the market.
How long does the solar panel take to fill it?
Days of good direct sun, not hours. Treat solar as a top-up that keeps the unit ready, and charge from USB-C when you have power.
Is it actually waterproof?
It is rated IP65: dust-tight and protected against water jets from any direction. Rain, spray and a wet pack are fine. It is not rated for submersion.
Can I take it on a plane?
Yes. At 37Wh it sits well under the 100Wh airline limit, so it travels in carry-on baggage. Lithium batteries must not go in checked luggage.
Can it charge more than one device at once?
Yes — up to three: two wired outputs plus the wireless pad. Charging several devices at once splits the available power, so each one charges more slowly.
What is the return policy?
30 days money-back if it isn't right for you, and a 90-day return window on the product itself. Details on our refund policy page.
