I Use This Portable Solar Charger All the Time and It’s Over 50% Off on Prime Day

Prime Day 2025 runs from Tuesday, July 8 through Friday, July 11, and Lifehacker is sharing the best sales based on product reviews, comparisons, and price tracking tools.

I put my solar power bank on the windowsill and forget about it until the power goes out. Then I can use it as a flashlight and a phone charger. If you’ve ever left the house and suddenly found your phone at 3% and the power is far away, or if you had a power outage and couldn’t charge your phone, a solar power bank is a great solution. This one is 52% off as part of Prime Day.

This is a single 5V, 42,800mAh solar power bank that can be used to charge your phone or other device via two USB/C ports. It can also work as an LED flashlight in the event of a power outage, and it is waterproof and chemical resistant to ensure durability. This mini battery can be charged around 1,600 times before the battery wears out, and the built-in magnetic protection protects it from damage, making it a reliable choice for backup charging, camping, or your emergency kit on the road. The device does not come with cables, so you will need a cable compatible with the device to charge it.

Why Solar Charging Is a Good Choice

If you use a solar powered battery pack to power outages, charging it will allow you to use your devices even when the power is out. However, if you use other types of backup power, such as a gas or propane generator, a solar powered backup can be a good addition to your kit since there is a possibility of gas and propane shortages in an emergency. Diversifying your power source can make your emergency kit more reliable. An added benefit of solar charging is that sunlight is free and available at all times of the day.

Why This Battery Pack Is a Favorite

This battery is my favorite because you can put it on a sunny windowsill and practically forget about it until you need it. It takes a while to charge, but that’s okay if you leave it for a long time. If you don’t have a full charge and you need it, it also has a wall charger, which allows you to plug it in and charge it faster.

What do you think at the moment?

Lightweight and durable, this power bank can be easily stashed in your glove compartment or bag for outdoor activities or as an emergency kit on the road. Shockproof and waterproof, it’s perfect for taking to the beach as a backup device just in case, or in your travel bag for an emergency kit.

I found myself using the flashlight more often than I expected because I always know that my solar power bank is sitting on the windowsill if the power goes out. When I pull it out in the dark, I use it to see the road while I gather up the rest of my supplies. You can also use the flashlight to be more visible if you need to get out of your car on the side of the road. Since the light is LED, it doesn’t drain the battery as quickly as you might expect, although I wouldn’t recommend using it as both a flashlight and charger for more than a few minutes.
