Overview of the Power Bank, Solar Charger, 36800mAh
For anybody who wants a bit more backup power in the wild, the Mregb solar bank tries to hit the sweet spot between high capacity and durability. It’s big enough to charge multiple devices, and people say it does well with phones, tablets, and smaller stuff. There’s also a flashlight and a hook, which is great for camping or just clipping it to your bag.
But let’s be real: the solar panel isn’t going to work miracles. It’s fine in a pinch, but if you’re counting on it for a full charge, you’ll be waiting a while. The rugged build is a plus, though—it’s waterproof, shockproof, and generally feels like it can survive a few bumps. The tradeoff? It’s not exactly lightweight.
High-Capacity Battery Performance
A lot of folks like that the Mregb bank keeps their devices going during outages or long trips. The big battery is supposed to handle several phone or tablet charges, which is solid if you’re off-grid for a bit. Still, not everyone’s convinced it actually delivers the full advertised capacity; a few have found it drains faster than expected.
Pros:
- Handles multiple device charges before needing a refill
- Handy for emergencies or travel
Cons:
- Some say the real capacity falls short of the specs
- Solar charging is slow, sometimes painfully so
Solar Charging Functionality
The built-in solar panel is a neat idea, but you’ll need patience. It’s more for emergencies than daily use. The panel’s size limits how much sunlight it can soak up, so don’t expect to go from empty to full in a day—especially if the weather isn’t cooperating.
People like having the solar option for camping or power cuts, but everyone seems to agree a wall charger is way faster. The solar panel is more about topping off the battery or getting a little extra power when you’re truly out of options.
Key Points:
- Emergency backup only; not a main charging method
- Charging speed depends a lot on sunlight
- Good for topping off, not full recharges
Multiple Device Compatibility
If you’re juggling a bunch of gadgets, this power bank is pretty flexible. It’s got both USB Type-A and USB Type-C ports, so you can plug in two things at once—maybe your phone and wireless earbuds, for example.
Charging speeds can vary, though, depending on what you’re plugging in. It doesn’t support every fast-charging tech out there, so if you need something very specific, double-check before buying.
Integrated Flashlight and Hook Design
Little touches make a difference, and the built-in flashlight is actually useful. You just hold the power button to turn it on or off—perfect for late-night walks to the bathroom at a campsite or digging through your bag in the dark.
That hook? Pretty handy, too. Clip it to your backpack or tent and you’re good to go. The flashlight is bright enough for most needs, though it won’t outshine a dedicated torch. Just make sure the hook is secure, or you might be retracing your steps looking for it. These features are nice, but if you’re headed into really rough conditions, you’ll probably want specialized gear.
Durability and Outdoor Usability
This thing’s built to take a beating. The tough ABS and PC shell can handle drops, and the IPX7 water rating means it won’t freak out if it gets wet. Dust protection is another plus.
The hook and carabiner make it easy to keep handy on hikes. Still, the solar panel’s usefulness depends a lot on the weather—some users say it’s just not that reliable unless the sun’s really out.
Summary Table:
| Feature | Outdoor Suitability |
|---|---|
| Water Resistance | IPX7 |
| Shock Protection | Yes |
| Dustproof | Yes |
Built-In Compass for Navigation
There’s a compass built in, which is a thoughtful touch for hikers. It’s not going to replace a real navigation device, but for quick checks, it’s fine. If you’re planning a serious trek or need precise navigation, bring a dedicated compass. For everyone else, it’s a handy backup.

Customer Reviews
Most people find this charger sturdy and useful, especially during blackouts, camping, or just being outside for a while. The dual USB ports and flashlight get lots of love. The solar and high capacity are nice, but not everyone’s thrilled with charging speed or the actual amount of power it delivers.

Still, plenty of users are happy with the convenience and design. It’s not perfect, but it does the job for basic charging and emergencies.
Frequently Asked Questions
How long does it take to fully charge the power bank using solar power?
Solar charging this thing takes a long time. It’s okay for emergencies, but don’t plan on relying on it as your main charging method. You’ll need strong sun and a lot of patience—think more than a full day for any real recharge.
For regular use, just plug it into a USB outlet. The solar panel is best for topping off the battery when you’re really stuck.
What devices are compatible with this solar charger?
The Mregb solar charger works with most smartphones (iPhones, Samsung, LG, HTC), tablets, and smaller accessories like smartwatches, headphones, cameras, and GPS units—as long as you’ve got the right cable.
Most people haven’t run into compatibility issues, but it’s worth using a decent cable for the best results. If your device needs a lot more power than a typical phone, it might not be supported.
Is the power bank waterproof and what does an IPX7 rating mean?
It’s rated IPX7, so it can handle being dunked in water up to a meter deep for half an hour. Rain, splashes, or a quick drop in a puddle shouldn’t be a problem.
That doesn’t mean you should take it swimming. Also, keep the ports covered and dry when you’re not using them to keep the waterproofing intact.
How powerful is the built-in flashlight and what are its uses?
The flashlight gets good marks for brightness. It’s handy for camping, hiking, or emergencies at home—enough to light up a tent or room for hours.
Just hold the power button to turn it on. It’s not going to compete with a heavy-duty tactical light, but for most outdoor or emergency uses, it’s more than enough.
Can this solar charger charge multiple devices simultaneously?
Yep, you can charge up to three devices at once using the available ports. It’s great for groups or when you’ve got a phone, headphones, and something else all needing juice.
Charging does slow down a bit with more devices plugged in, though. If you want the fastest charge, stick to one device at a time.
What safety features are included to protect devices during charging?
There are built-in safety features designed to keep things in check—stuff like overcharge protection, heat control, and short circuit safeguards. The power bank’s smart transformer chip actually tweaks the current for each device, which is pretty neat.
Most folks say their charging experience has been smooth, no weird safety hiccups. That said, it’s always smart to stick with good cables and actually read the manufacturer’s directions (even if you’re tempted to skip them).
