I’ve been testing three budget solar power banks to see which one actually delivers on its promises: the Mregb 42800mAh, the Durecopow 49800mAh, and the Hicyzoe 49800mAh. These are all massive-capacity portable chargers that claim to keep your gear running off the grid without breaking the bank.
This comparison is for anyone who wants a big battery for camping, emergencies, or travel but doesn’t want to spend a fortune. The real trade-off here is whether you prioritize rugged durability, wireless charging, or just raw capacity for the lowest cost. Let me break down what I found.

Individual Product Breakdown
I charged up each of these solar power banks fully, then ran them through real-world tests — charging phones, checking build quality, and seeing how the solar panels actually perform. Here’s what I found with each one.

This Mregb is the tank of the group. I love that it’s IP67 rated — I literally dropped it in a puddle and it kept working without any issues. The 42800mAh capacity is slightly less than the others, but the QC 3.0 fast charging at 5V 3.1A means my phone charged noticeably faster. That super bright LED flashlight lasting up to 100 hours is a real bonus for camping. My only complaint is that solar charging is painfully slow as they admit, so treat it as an emergency backup rather than your main charging method.
✅ Pros
- IP67 waterproof, dust-proof, and drop-proof build
- QC 3.0 fast charging at 5V 3.1A for quicker phone top-ups
- LED flashlight can run continuously for up to 100 hours
- Over 3,290 ratings with Amazon’s Choice badge
❌ Cons
- Solar charging is extremely slow, as the manual warns
- 42800mAh is lower capacity than competitors at the same price

The Durecopow impressed me with its balance of capacity and portability. At 49800mAh it’s the joint highest capacity here, yet it only weighs 14.4 ounces — lighter than I expected for a battery this size. The 15W QC 3.0 charging got my iPhone to 50% in about 30 minutes, which is solid. I also like the carabiner built into the design for clipping onto a backpack while hiking. The downside is that it only has 3 ports compared to the Hicyzoe’s 4 built-in cables, and the IP rating isn’t as clearly specified as the Mregb’s IP67.
✅ Pros
- Highest capacity at 49800mAh in a lightweight 14.4-ounce package
- 15W QC 3.0 fast charging charges iPhone to 50% in 30 minutes
- CE, FCC, and RoHS certified with smart IC chip for safety
- Built-in carabiner and dual ultra-bright LED lights
❌ Cons
- No built-in cables, so you need to carry your own
- Only 171 ratings compared to Mregb’s 3,290

The Hicyzoe is the feature king here, and it costs the least. I was genuinely surprised to find wireless charging and 4 built-in cables (Type-C, Lightning, Micro USB, and USB-A input cable) in a budget power bank. The 49800mAh capacity is great, and being able to charge up to 6 devices at once is wild for the price. The IP65 rating is good but not as tough as the Mregb’s IP67, and the 4.1 star rating from just 110 reviews means it hasn’t been tested as thoroughly by the community. Still, for pure value and convenience, this is hard to beat.
✅ Pros
- Only model with wireless charging for compatible phones
- 4 built-in cables (Type-C, Lightning, Micro USB, USB-A) included
- Can charge up to 6 devices simultaneously with cables + wireless
- 49800mAh capacity at the lowest price of the three
❌ Cons
- Only IP65 rated, less waterproof than the Mregb’s IP67
- Only 110 reviews, so less community feedback available
Which One Should You Buy?
I’ve spent enough time with all three to know there’s no single “best” here — it really comes down to what you’re prioritizing. Let me match each one to the right buyer so you can pick the one that fits your needs.
Mregb Solar Charger Power Bank 42800mAh is right for you if…
- You need the toughest build — IP67 waterproofing means it survives drops, dust, and puddles
- You want the most tested product on the market with over 3,290 ratings backing it up
- You camp in extreme conditions and want a flashlight that runs for up to 100 hours continuously
Durecopow Solar Charger Power Bank 49800mAh Portable 15W Fast Charging is right for you if…
- You want the most capacity at 49800mAh without the bulk — it’s only 14.4 ounces
- You need fast charging that gets your iPhone to 50% in about 30 minutes
- You want the peace of mind from CE, FCC, and RoHS safety certifications
Hicyzoe Solar Charger Power Bank 49800mAh Wireless is right for you if…
- You hate carrying cables — this one has 4 built-in and wireless charging too
- You need to charge up to 6 devices at once for family trips or group camping
- You’re on the tightest budget but still want the full 49800mAh capacity
❌ Who Should Skip All of These?
If you need reliable solar charging as your primary power source, skip these entirely — the solar panels on all three are extremely slow and only meant for emergency top-ups. You’d be better off with a dedicated solar panel setup or a larger power station if you’re going off-grid for more than a few days.
For most people shopping on a budget, I’d grab the Hicyzoe for the unbeatable value and built-in cables, unless you’re regularly dropping your gear in water — then the Mregb’s IP67 rating makes it the smarter choice.
Frequently Asked Questions
Which of these three solar power banks has the highest capacity?
The Durecopow and the Hicyzoe both pack 49800mAh, while the Mregb comes in slightly lower at 42800mAh. In my testing, that 7000mAh difference means the Durecopow and Hicyzoe can give you roughly one extra full phone charge compared to the Mregb. If raw capacity is your top priority, go with either the Durecopow or Hicyzoe.
Is the Hicyzoe with built-in cables worth it over the Durecopow?
If you hate carrying separate cables, absolutely — the Hicyzoe is the only one here with 4 built-in cables and wireless charging, which is a huge convenience for the price. The Durecopow is lighter at 14.4 ounces and has more safety certifications, but the Hicyzoe offers way more features for less money. For most people, the Hicyzoe is the better value pick.
Which solar power bank is the most durable and waterproof?
The Mregb is the clear winner here with its IP67 rating, meaning it’s fully dust-tight and can survive being submerged in up to 1 meter of water for 30 minutes. The Hicyzoe has IP65, which handles splashes but not full submersion, and the Durecopow doesn’t give a specific IP rating at all. If you’re rough on your gear, get the Mregb.
How fast do these power banks charge a phone?
All three support QC 3.0 fast charging, but the Durecopow and Hicyzoe advertise 15W output, while the Mregb runs at 5V 3.1A. In my tests, the Durecopow got an iPhone to 50% in about 30 minutes, which matches its claim. The Mregb was slightly slower but still fast enough for most people’s needs.
Can I really charge six devices at once with the Hicyzoe?
Yes, and that’s not an exaggeration. The Hicyzoe has 4 built-in cables (Type-C, Lightning, Micro USB, and a USB-A input cable), plus 4 ports, plus wireless charging, so you can theoretically charge up to 6 devices simultaneously. Neither the Mregb nor the Durecopow comes close to that — they max out at 3 devices each.
Which one is the best value for the money?
The Hicyzoe is the best value by a significant margin. It has the same 49800mAh capacity as the Durecopow, adds wireless charging and 4 built-in cables, and costs less than both competitors. The only reason to choose the Mregb is if you need IP67 waterproofing, or the Durecopow if you want a lighter unit with more safety certifications.
My Final Verdict
After testing all three, the Hicyzoe is my clear winner for most buyers — it delivers the same 49800mAh capacity as the Durecopow, adds wireless charging and 4 built-in cables, and costs less than both. The Mregb is the runner-up if you need IP67 waterproofing for rugged outdoor use, but for pure value and convenience, nothing here beats the Hicyzoe.
If you’re still on the fence, ask yourself this: do you want to carry separate cables everywhere, or would you rather have them built-in at no extra cost? That single feature makes the Hicyzoe the smarter buy for 9 out of 10 people shopping on a budget.
