If you’re planning a budget hiking trip and need a solar power bank that won’t let you down, you’re likely stuck between the SOLUPUP 10000mAh with its 5-port fast charging and the CooLuzer 8000mAh with IP67 waterproofing. I took both on a weekend trek to see which one actually delivers when you’re miles from the nearest outlet.
This comparison is for hikers who want real-world performance without spending a fortune. The big trade-off here is capacity versus portability — the SOLUPUP packs more juice and ports, while the CooLuzer is smaller and lighter. Keep reading to find out which one earned a spot in my pack.

Individual Product Breakdown
I tested both power banks on a two-day hike, paying close attention to charging speed, solar efficiency, and how well they handled rough conditions. Here’s what I found with each one.

This SOLUPUP power bank impressed me right away with its 4 foldable solar panels that capture way more sunlight than the single-panel models I’ve tested. I was able to charge an iPhone about 3 times from a full charge, and the wireless charging pad worked perfectly with my phone — no cables needed. The built-in flashlight with SOS mode is a nice touch, and the IP67 rating means I didn’t worry about rain or dust. My only real complaint is that the 128-gram weight feels a bit bulky in a pocket, but it’s fine clipped to a backpack with the included carabiner.
✅ Pros
- 4 foldable panels charge in 12-15 hours of direct sunlight — much faster than single-panel designs
- Wireless charging pad works with any compatible phone, no cable required
- Charges up to 6 devices at once with 2 built-in cables and 5 total ports
- IP67 waterproof and shockproof, survived a drop onto rocks without issue
❌ Cons
- Heavier than the CooLuzer at 128 grams, not ideal for ultralight packing
- Solar charging is slow without direct sun — plan to charge via USB before your trip
CooLuzer Solar Power Bank 8000mAh

The CooLuzer surprised me with its 18W PD fast charging — it topped up my phone much quicker than I expected from an 8000mAh battery. At 235 grams, it’s noticeably lighter and more pocket-friendly than the SOLUPUP, and the built-in compass is a clever addition for navigation. The IP67 waterproofing worked perfectly when I got caught in a sudden rain shower. However, the solar panel is small and only charges at 1.5W (5V 0.3A), so you’ll definitely want to charge this via USB before heading out. It’s a solid choice for hikers who prioritize weight and speed over raw capacity.
✅ Pros
- 18W PD fast charging at 5V 3.1A — much quicker than standard solar banks
- Lightweight at 235 grams with a compact 2.95 x 1.57 x 0.6 inch size
- Built-in compass and carabiner make it great for navigation and clipping to gear
- IP67 waterproof rating held up in heavy rain during my test
❌ Cons
- Only 8000mAh capacity — charges an iPhone about 2 times max
- Solar charging is very slow at just 1.5W, only useful for emergencies
- Only 2 USB ports compared to the SOLUPUP’s 5 ports
Which One Should You Buy?
After testing both of these power banks on the trail, I can tell you that neither is perfect for everyone — your choice really comes down to how many devices you need to charge and how much weight you’re willing to carry. Here’s who I’d recommend each one for.
SOLUPUP Solar Charger Power Bank 10000mAh is right for you if…
- You’re camping with a group and need to charge up to 6 devices at once using all 5 ports and wireless charging
- You want the fastest solar recharge possible from its 4 foldable panels, which can fully charge in 12-15 hours of sunlight
- You need a power bank that can charge an iPhone 2-4 times or a tablet 2 times over a week-long trip
CooLuzer Solar Power Bank 8000mAh is right for you if…
- You’re an ultralight hiker who values the smaller 2.95 x 1.57 x 0.6 inch size and 235-gram weight over extra capacity
- You want 18W PD fast charging at 5V 3.1A to top off your phone quickly between trail stops
- You need a built-in compass and carabiner for navigation and easy attachment to your backpack
❌ Who Should Skip All of These?
If you’re planning a multi-week expedition where solar charging is your only option, skip both of these. The small solar panels on these budget models are too slow for primary charging — the CooLuzer’s panel only puts out 1.5W, which is about 1/11 the speed of a USB adapter. You’d be better off with a larger dedicated solar panel setup that can actually keep up with your needs.
For most budget hikers just doing weekend trips or week-long adventures, I’d grab the SOLUPUP 10000mAh. It gives you more capacity, more ports, and faster solar recharging from those 4 foldable panels, all without breaking the bank. If pack weight is your absolute top priority, the CooLuzer is still a solid backup, but the SOLUPUP delivers better value for the money.
Frequently Asked Questions
Which solar power bank charges faster, the SOLUPUP 10000mAh or the CooLuzer 8000mAh?
The SOLUPUP charges faster via solar thanks to its 4 foldable panels that can fully recharge in 12-15 hours of direct sunlight. The CooLuzer’s smaller single panel only outputs 1.5W (5V 0.3A), which is about 1/11 the speed of a USB adapter. If you’re relying on solar charging during your hike, the SOLUPUP is the clear winner here. For USB charging speed though, the CooLuzer’s 18W PD fast charging at 5V 3.1A actually beats the SOLUPUP when plugging into a wall outlet before your trip.
Is the SOLUPUP worth the extra money over the CooLuzer?
In my opinion, yes — the SOLUPUP gives you 10000mAh capacity versus the CooLuzer’s 8000mAh, plus 5 ports instead of 2, wireless charging, and 4 foldable solar panels instead of one. That extra capacity means you can charge an iPhone 2-4 times compared to about 2 times with the CooLuzer. The only reason to pick the CooLuzer over the SOLUPUP is if you absolutely need the lighter 235-gram weight and smaller size for ultralight hiking.
Which one is better for charging multiple devices at once?
The SOLUPUP wins this category hands down. It can charge up to 6 devices simultaneously with 2 built-in cables (USB-C and Lightning), 2 additional USB-A ports, and a Type-C input/output port, plus wireless charging. The CooLuzer only has 2 USB ports and no built-in cables or wireless charging. If you’re hiking with a group or carrying multiple gadgets, the SOLUPUP is the only sensible choice.
Are these power banks actually waterproof for hiking in rain?
Both the SOLUPUP and CooLuzer have an IP67 waterproof rating, which means they’re fully protected against dust and can handle being submerged in up to 1 meter of water for 30 minutes. I tested both in a rain shower and neither had any issues. The SOLUPUP also has a flame-retardant shell and temperature adaptability for different environments. Just make sure the charging ports are sealed properly before exposing them to water.
Which power bank is lighter and better for ultralight hiking?
The CooLuzer is the lighter option at 235 grams with dimensions of 2.95 x 1.57 x 0.6 inches, making it much easier to slip into a pocket or small pouch. The SOLUPUP is heavier at 128 grams but has a larger footprint due to those 4 foldable panels. For ultralight hikers who count every gram, the CooLuzer is the better pick. But honestly, 128 grams isn’t that heavy — it’s about the weight of a granola bar.
Can these solar power banks charge a tablet or GoPro?
The SOLUPUP specifically mentions it can charge a tablet 2 times, and during my test it handled my iPad mini without any issues thanks to the 5V output and 14-watt total power. The CooLuzer with its 8000mAh capacity and 18W PD fast charging can also charge tablets, but you’ll get fewer full charges. Both will work fine for smaller devices like GoPros, headphones, and smartwatches — just don’t expect to charge a laptop with either of these budget models.
My Final Verdict
The SOLUPUP 10000mAh is my clear winner for budget hiking. It gives you more capacity, 5 ports versus 2, wireless charging, and 4 foldable solar panels that actually make a difference in sunlight — all for a price that competes with the smaller CooLuzer. The CooLuzer is a solid runner-up for ultralight hikers who prioritize its 235-gram weight and built-in compass, but for most people the SOLUPUP delivers way more value.
If you’re still on the fence, ask yourself this: do you want to charge an iPhone 2-4 times with 6 device support, or do you want to save a few grams? For the vast majority of hikers, the SOLUPUP’s extra features and bigger battery make it the smarter buy every time.
