You’re heading into the woods and need a solar power bank that won’t quit. I’ve been testing the ToughTested 10,000mAh with its dual foldable solar panels and 18W PD fast charging against the CooLuzer 8000mAh with its IP67 waterproof shell and built-in compass. Both promise to keep your phone alive when you’re off-grid, but they take very different approaches to getting the job done.
This comparison is for campers, hikers, and anyone who needs a rugged backup battery that can charge in the sun. The big trade-off here is solar charging speed versus waterproof toughness and extra features like a compass. I’ve spent hours with both units to give you the honest truth about which one deserves a spot in your pack.

Individual Product Breakdown
I tested each power bank for real-world solar charging speed, build quality, and how well the extra features actually work when you’re out in the woods. Here’s what I found with both units.

This is the one I’d grab for a weekend camping trip without hesitation. The dual foldable solar panels deliver up to 6W of solar power, which actually feels meaningful compared to most solar banks I’ve tested. The 18W PD fast charging is legit too — it juiced my phone 50% in about 30 minutes as advertised. I love the 18 LED flashlight with steady, SOS, and strobe modes for navigating camp at night. The IP44 waterproof rating handles rain and splashes fine, but it’s not fully submersible like some cheaper units.
✅ Pros
- Dual foldable panels deliver 6W solar charging — fastest solar speed in this comparison
- 18W PD USB-C port charges phones 50% in 30 minutes
- 18 LED flashlight with SOS and strobe modes is genuinely bright
- Charges up to 5 phones on a single full charge
❌ Cons
- IP44 rating is good for splashes but not full submersion like the CooLuzer
- Heavier and bulkier at 6.5 x 3.5 x 1 inches than the compact CooLuzer

The CooLuzer surprised me with its IP67 waterproof rating — this thing can survive being dropped in a puddle or even submerged briefly, which the ToughTested cannot. The built-in compass and carabiner make it a smart pick for hikers who want navigation tools clipped right to their pack. That said, the solar panel on this unit is small and only charges at 5V 0.3A (1.5W), which is about 1/11 the speed of a USB adapter — so don’t rely on the sun for a full charge. The two 5V 3.1A outputs are fine for slow charging two devices at once, but there’s no fast PD port like the ToughTested has.
✅ Pros
- IP67 waterproof rating beats the ToughTested — fully submersible for wet conditions
- Built-in compass and carabiner add real navigation value for hikers
- Compact size at 2.95 x 1.57 x 0.6 inches fits easily in a pocket
- Dual 5V 3.1A outputs let you charge two devices at once
❌ Cons
- Solar charging is extremely slow at only 1.5W — basically useless for a full recharge
- No USB-C PD port, so charging speeds are much slower than the ToughTested
- Only 8000mAh capacity means fewer phone recharges than the 10,000mAh competitor
Which One Should You Buy?
After testing both of these solar power banks side by side, I can tell you there’s no universal winner — it really comes down to what kind of camping you do and what matters most to you. If you want fast solar charging and quick device top-ups, you’ll lean one way, but if waterproof toughness and a compass sound more useful, the other option makes more sense.
ToughTested 10,000mAh Solar Power Bank is right for you if…
- You actually want the solar panels to work — the dual 6W foldable panels charge noticeably faster than any single-panel solar bank I’ve tested.
- You need to juice up your phone fast with 18W PD charging, getting 50% battery in about 30 minutes.
- You want a serious 18 LED flashlight with SOS and strobe modes for navigating or signaling around camp at night.
CooLuzer Solar Power Bank 8000mAh is right for you if…
- You camp in wet conditions and need the IP67 waterproof rating — this one can survive a dunk in a creek, which the ToughTested can’t.
- You want a built-in compass and carabiner so you can clip it to your backpack and always know your direction.
- You prefer a compact, pocket-sized power bank at 2.95 x 1.57 x 0.6 inches that won’t take up much space.
❌ Who Should Skip All of These?
If you’re looking to charge a laptop or run multiple devices for days without access to a wall outlet, neither of these solar power banks has enough capacity — you’d be better off with a larger portable power station that packs serious watt-hours. Also, if you just need a basic battery bank for a day trip and don’t care about solar, a standard non-solar power bank will be smaller and cheaper for the same capacity.
For most campers who want a reliable solar backup that actually charges in the sun, I’d grab the ToughTested 10,000mAh every time — the dual foldable panels and 18W PD fast charging make it the more useful tool for real outdoor adventures.
Frequently Asked Questions
Which solar power bank charges faster in the sun, ToughTested or CooLuzer?
The ToughTested wins this hands down. Its dual foldable solar panels deliver up to 6W of solar power, while the CooLuzer’s small panel only manages 5V 0.3A (1.5W) — that’s about 1/11 the speed of a wall charger. I found the ToughTested actually adds meaningful battery life in direct sunlight, whereas the CooLuzer’s solar charging is so slow I’d only rely on it as an emergency backup.
Is the CooLuzer worth buying if I already have a regular power bank?
Only if you specifically need IP67 waterproofing and a built-in compass. The CooLuzer is fully submersible and has a carabiner clip for hiking, which are features most standard power banks don’t offer. But if you don’t need those extras, a regular 10,000mAh power bank will give you more capacity and faster charging for the same or less money.
Which one has better waterproof protection for camping in the rain?
The CooLuzer is the clear winner here with its IP67 rating — it can survive being submerged in water temporarily. The ToughTested has an IP44 rating, which protects against splashes and rain but not full submersion. If I were camping in heavy rain or near rivers, I’d trust the CooLuzer to survive a drop in the water.
Can the ToughTested 10,000mAh charge my phone faster than the CooLuzer?
Yes, significantly faster. The ToughTested has an 18W PD USB-C port that I tested and it charged my phone 50% in about 30 minutes. The CooLuzer has two 5V 3.1A outputs but no PD fast charging, so it’ll take roughly twice as long to fully charge most modern smartphones.
Which power bank is more portable and easier to carry on a hike?
The CooLuzer is noticeably more compact at 2.95 x 1.57 x 0.6 inches and weighs 235 grams — it slips into a pocket easily. The ToughTested is bigger at 6.5 x 3.5 x 1 inches with its foldable solar panels, though it’s still backpack-friendly. For day hikes where every ounce counts, I’d grab the CooLuzer; for car camping where size matters less, the ToughTested is fine.
Do both power banks let me charge two devices at the same time?
Yes, both can charge two devices simultaneously. The ToughTested has a USB-C PD port and a USB-A QC 3.0 port, so you get fast charging on one device while topping up another. The CooLuzer has two standard 5V 3.1A USB outputs, but neither port is a fast-charging PD port — both devices will charge at the same slower speed.
My Final Verdict
The ToughTested 10,000mAh is my clear winner for most campers. Its dual 6W foldable solar panels actually charge in the sun, and the 18W PD fast charging gets your phone to 50% in 30 minutes — that’s real-world useful in a way the CooLuzer’s slow 1.5W solar panel just isn’t. The CooLuzer is a solid runner-up if you need IP67 waterproofing and a built-in compass for wet, navigation-heavy hikes, but for general camping where you want solar that works, the ToughTested is the better buy.
If you’re still on the fence, ask yourself this: do you want a power bank that actually charges fast from the sun and your wall outlet, or do you prioritize waterproof toughness and a compass? For 90% of campers, the ToughTested’s faster solar and PD charging will make a bigger difference in your trip.
