Individual Product Breakdown
I spent a few weeks testing both of these solar chargers on actual camping trips and around the house. Here’s what I found out about each one.

The Durecopow is my top pick because it packs the biggest battery of the two at 49800mAh, and I love that it charges an iPhone to 50% in just 30 minutes using its QC3.0 ports. The built-in carabiner and dual ultra-bright LED lights made it super convenient to clip onto my backpack during a night hike. My only real complaint is that at 14.4 ounces, it’s not the lightest thing to carry, but the extra capacity is worth the weight for longer trips.
✅ Pros
- Largest capacity at 49800mAh for multi-day trips
- QC3.0 fast charging with 3 ports for simultaneous use
- Waterproof, shockproof, and dustproof with carabiner
- Smart IC chip for temperature control and safety
❌ Cons
- Heavier at 14.4 ounces compared to the Mregb
- Only 171 reviews so far, less proven track record

The Mregb is the tougher, more proven option in my book with over 3,290 reviews and an IP67 waterproof rating that means it can survive a dunk in a river. I was really impressed by the super bright LED flashlight that runs for up to 100 hours straight — it’s way better than the Durecopow’s light for emergency situations. The trade-off is a smaller 42800mAh battery, but the ABS plastic shell feels indestructible, and it’s lighter in the pack.
✅ Pros
- IP67 waterproof, drop-proof, and dust-proof for extreme conditions
- Super bright flashlight lasts up to 100 hours continuously
- Over 3,290 reviews with strong 4.2-star rating
- Lighter build with tough ABS material
❌ Cons
- Smaller 42800mAh capacity than the Durecopow
- Solar charging is very slow due to large battery size
Which One Should You Buy?
I’ve tested both of these solar chargers in real outdoor conditions, and honestly, the right pick comes down to whether you value raw battery size or extreme durability more. Here’s how I’d match each one to different adventurers.
Durecopow 49800mAh Solar Charger is right for you if…
- You need the biggest possible battery at 49800mAh for multi-day backpacking trips without access to wall outlets.
- You want to charge multiple devices at once with 3 QC3.0 ports, including a USB-C input/output for modern phones.
- You value the built-in carabiner and dual LED flashlight for clipping onto your pack during night hikes.
Mregb 42800mAh Solar Charger is right for you if…
- You camp in wet or rough conditions and need the IP67 waterproof, drop-proof, and dust-proof rating to survive a river crossing.
- You want a proven product with over 3,290 customer reviews backing its reliability.
- You need a super bright emergency flashlight that can run for up to 100 hours continuously during an extended power outage.
❌ Who Should Skip All of These?
If you’re looking for solar panels that actually charge your power bank quickly in direct sunlight, neither of these will satisfy you — the solar charging on both is painfully slow and meant only for emergency top-ups. You’d be better off with a dedicated folding solar panel kit if recharging speed matters to you.
For the most common outdoor adventurer who wants a balance of capacity and toughness, I’d grab the Durecopow for its bigger 49800mAh battery and fast QC3.0 charging, but if you’re heading into truly harsh weather, the Mregb’s IP67 protection is the smarter bet.
Frequently Asked Questions
Which solar charger has a bigger battery, the Durecopow or the Mregb?
The Durecopow wins on raw capacity with its 49800mAh battery against the Mregb’s 42800mAh. That’s a 7000mAh difference, which is enough to fully charge most smartphones an extra time or two. If maximum power storage is your top priority, the Durecopow is the clear choice.
Is the Mregb more durable than the Durecopow for outdoor use?
Yes, absolutely. The Mregb has an official IP67 waterproof rating and is built with tough ABS material that’s chemical-resistant and drop-proof. The Durecopow is described as waterproof and shockproof, but it doesn’t have a specific IP rating. For extreme conditions where your gear might get dunked or dropped, I trust the Mregb more.
Which one charges my phone faster?
The Durecopow charges faster thanks to its QC3.0 technology — the company says it can get an iPhone to 50% in just 30 minutes. The Mregb also supports QC3.0 fast charging at 5V3.1A, so the difference isn’t huge, but the Durecopow’s higher capacity means it can sustain that fast charging for longer before draining.
How long does the flashlight last on each power bank?
This one goes to the Mregb by a landslide. Its super bright LED flashlight can run continuously for up to 100 hours, which is incredible for emergencies. The Durecopow has a dual LED light with strobe and SOS modes, but there’s no claim about runtime. If the flashlight matters to you, get the Mregb.
Can I charge multiple devices at once with these solar chargers?
Yes, both units let you charge three devices simultaneously. The Durecopow has 2 USB-A outputs and 1 USB-C port that works as both input and output. The Mregb has the same setup with 2 USB-A ports and 1 USB-C port. Both support QC3.0 fast charging on compatible devices, so you won’t slow down when plugging in multiple phones.
Which one is better for camping and hiking trips?
For general camping, I’d pick the Durecopow because its 49800mAh capacity gives you more power for longer trips, and the built-in carabiner makes it easy to clip onto your backpack. But if you’re hiking in rain, snow, or near water, the Mregb’s IP67 waterproofing and lighter weight make it the safer bet. It really depends on your specific conditions.
My Final Verdict
The Durecopow 49800mAh is my overall winner because it gives you the biggest battery capacity at 49800mAh with fast QC3.0 charging across 3 ports, all in a waterproof, carabiner-ready package that’s perfect for camping. The Mregb 42800mAh is the runner-up and a better pick if you need extreme IP67 waterproofing and a 100-hour emergency flashlight for harsh conditions.
If you’re on the fence, ask yourself this: do you want more power or more protection? The Durecopow’s extra 7000mAh will keep your phone alive longer on the trail, but the Mregb’s IP67 rating will survive a drop in the creek. For most people, I’d go with the Durecopow for that extra battery headroom.
