Watch Out For Cheap Replicas.

Oolia is the original solar power bank, trusted by thousands of satisfied customers.

How many times can it fully charge my phone?

You can expect around 2–2.5 full charges for most iPhones and Samsung Galaxy phones—enough to help keep you powered through a weekend trip without hunting for an outlet. No inflated numbers, just a clear idea of what you can expect. Actual charges vary by phone model and usage.

Can it charge multiple devices at the same time?

Yes—charge up to 3 devices at once using the USB-C port, USB-A port, and wireless charging together. That means you, your partner, and your kid can all power up from one power bank. No taking turns or arguing over who charges first.

How long does the solar panel actually take to charge this?

Let’s be honest—the solar panel is there for backup. If you’re camping or dealing with a power outage, it will slowly add power in direct sunlight when an outlet isn’t an option. For a full charge, plug the power bank into a compatible USB-C charger before heading out. Solar charging depends on sunlight and conditions, but when you’re without power, you’ll be glad you have another option.

Is it waterproof? How durable is it?

It's rated IPX4 splashproof, meaning rain, sweat, splashes, and spills won't hurt it. It's also dustproof and shockproof with a rugged ABS + PC shell and reinforced rubber edges. Toss it in your backpack, clip it to your bag with the included carabiner — it's built for the outdoors, not a desk drawer.

Stay connected when you need it most.

From winter storms and unexpected power outages to long days away from an outlet, the Oolia Solar Power Bank keeps backup power close. Charge your phone, check weather updates, and stay in touch with family—whether you’re at home or on the go.

✅ Portable backup power for your everyday devices
✅ Dual LED flashlights when the lights go out
✅ Supplemental solar charging when an outlet isn’t available
✅ Easy to keep nearby at home, on trips, or outdoors

Keep it fully charged before a winter storm and ready for everyday low batteries, unexpected outages, and your next trip.

Solar Power

A wall charger only helps when there’s an outlet.

When you’re camping, traveling, or facing a power outage, a low phone battery can leave you without maps, messages, or a way to reach family.

Our power bank keeps backup power within reach. Charge multiple devices, use the built-in LED flashlight after dark, and turn to solar charging for a little extra power in direct sunlight. Charge it fully by USB before your next trip so you’re ready when an outlet isn’t.
