When I was in my mid-20s and a first-time homeowner, I didn’t give much thought to emergency preparedness. I used to think power outages were only minor annoyances. Just light a few candles and enjoy a tech-free night, right? Then I had a child. The first outage we experienced with him left me more panicked than I had ever been over something like that. Suddenly, I became very aware of all the things that can go wrong without electricity, including not being able to pull up “Bluey” on demand.
That stressful stretch of a few hours pushed me into a mindset of being prepared that I had never really had before. The plain truth is that if your home doesn’t have a solar generator or some kind of power bank, you are not fully prepared. That applies even if you don’t have children, whether you’re older, have mobility issues, or live alone.
Fortunately, there may be an especially strong and affordable option: Mregb’s solar charger power bank, a compact portable charger that shoppers call a “lifesaver” because it works quickly and efficiently, and it costs just $20.
“This battery pack didn’t really wow me until this past week when I had an emergency that required me to travel across state lines with only what could fit in my pockets,” one reviewer says. 👀
“The clip held the pack to my belt loop securely,” they continued.
“Battery life from being fully charged kept my phone from dying for almost 2 days, and there was still juice left. At one point my wallet fell in a dark crevice and the flash light came in handy for such a task. This battery pack really proved its worth.”
Here’s how it works.
The solar charging power bank has a 42,800mAh battery capacity and uses high-density batteries, making it powerful while still easy to carry.
It can charge up to three devices at once and works as both an input and an output, depending on what your devices need. It is compatible with all USB-powered devices. It also includes a bright LED flashlight, which can be especially useful if an outage leaves you in total darkness.
For extra peace of mind, the charger is waterproof, meaning it can withstand submersion in water up to a meter deep for 30 minutes, and it is also protected against dust buildup. And if you tend to be clumsy, it is described as drop-proof and shock-resistant, which makes it harder to damage.
Customers say it can fully charge a phone at least three to four times before the power bank itself needs to be recharged.
One important note is that the power bank is fairly large. That makes it useful for keeping devices powered, but it also means it charges slowly by solar power. The solar feature is best reserved for emergencies, and the unit should be fully charged ahead of time. Charge it as soon as you get it, then keep it somewhere you will remember so it is ready when you need it.
Of course, it isn’t only good for emergencies.
This device is also a smart item to pack for vacations, especially outdoor trips. It is a solid choice for long hikes as well because it is fairly compact. “This charger has been a lifeline for me while camping,” shopper Jonathan Resnic says.
“Everyone at the campsite really appreciated the charging capabilities of this battery! 10/10. The solar panel charger helped out too! I take this all over the place now and use it day to day.”
At just under $30, the peace of mind it offers is difficult to put a price on.
Don’t be like mid-20s me. Invest in this small device that can make a big difference in a pinch. Want more proof from people who own it and love it? Check below for more reviews.
“This is perfect for when your power goes out. For the past two years in our state we have had issues with our electricity going out during the winter months when it freezes. This is a lifesaver during such trying times. We plan to put in our ‘emergency to go bag.’ A nice dependable and stable power bank. It keeps its power for a extended period of time. Glad I made the purchase. I would definitely recommend it. The package was delivered in a speedy fashion and was securely packaged.” — C.Smile
