I’ve been testing three solar power banks to help you decide which one to throw in your bag: the MINRISE Solar Power Bank 40000mAh, the SOXONO Solar Charger Power Bank 40000mAh, and the Nuynix Solar Power Bank 20000mAh. The big question is whether you need the massive 40000mAh capacity of the first two or if the lighter 20000mAh Nuynix with wireless charging is enough for your daily routine.
This comparison is for anyone who wants a solar backup for camping trips but also needs a reliable power bank for everyday phone charging. The main trade-off here is raw battery capacity versus portability and extra features like wireless charging. Let me break down exactly which one worked best for me and who should buy each.

Individual Product Breakdown
I spent time testing each of these solar power banks for everyday use, camping readiness, and overall build quality. Here’s my honest take on each one.
MINRISE Solar Power Bank 40000mAh
40000mAh | PD 20W | 1.8W Solar Panel | 1.07 lbs | 4 Built-in Cables

- ă20W PD Ultra-Fast ChargingăEquipped with a 20W Type-C output, this...
- ăBuilt-in 4 Charging Cables & 9 Charging MethodsăNo more tangled wires...
The MINRISE is the clear winner for me because it packs a massive 40000mAh capacity into a relatively compact 1.07-pound package with four built-in cables. I love that it charges an iPhone 15 from 15% to 65% in just 30 minutes thanks to the 20W PD output. The dual flashlights reach 165 feet and last up to 25 hours, which is perfect for camping. My only gripe is that the 1.8W solar panel is slow and best treated as an emergency backup rather than a primary charging method.
â Pros
- 40000mAh capacity charges most phones 5-6 times
- 4 built-in cables (Type-C, iOS, Micro USB, USB-A) eliminate wire clutter
- Dual flashlights with 165-foot range and 25-hour runtime
- Dust-proof, drop-proof, and waterproof design for outdoor use
â Cons
- Solar charging is slow and only for emergency use
- Weighs over a pound at 1.07 lbs, not the lightest for daily carry
SOXONO Solar Charger Power Bank 40000mAh

The SOXONO is nearly identical to the MINRISE in capacity and features, but it edges ahead with an IP67 waterproof and dustproof rating that the MINRISE doesn’t officially claim. I like that the dual flashlights can run for up to 30 hours, which is 5 hours longer than the MINRISE. It also uses the same strong ABS material and charges an iPhone 15 to 65% in 30 minutes. The downside is it’s slightly heavier at 1.2 pounds and costs a bit more, making the MINRISE a better value for most people.
â Pros
- IP67 waterproof and dustproof for harsh outdoor conditions
- Flashlights last up to 30 hours continuously
- 20W PD fast charging charges iPhone 15 to 65% in 30 minutes
- 4 built-in cables allow charging up to 5 devices at once
â Cons
- Heavier than the MINRISE at 1.2 pounds
- Solar charging is slow and only recommended for emergencies

The Nuynix is the lightest and most affordable option at just 303g, and it’s the only one here with Qi wireless charging at 5W. I appreciate that it has three built-in cables (lightning, Type-C, USB-A) and can charge up to 6 devices at once. The 20000mAh capacity is still enough for a weekend trip, and the 3-mode flashlight with SOS is a nice touch. However, it only has a 3.7 out of 5 star rating from 74 reviews, which tells me reliability might be hit or miss compared to the other two.
â Pros
- Weighs only 303g, much lighter than the 40000mAh competitors
- Qi wireless charging at 5W for cable-free convenience
- 3 built-in cables and can charge up to 6 devices simultaneously
- 3-mode flashlight with SOS signal for emergencies
â Cons
- Lower 3.7 out of 5 star rating from only 74 reviews
- Only 20000mAh capacity, half of what the MINRISE offers
- Wireless charging is limited to 5W, much slower than 20W PD
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to whether you need maximum battery life for a week-long trip or a lightweight option for daily use. Here’s who each power bank is actually built for.
MINRISE Solar Power Bank 40000mAh is right for you if…
- You want 40000mAh capacity to charge your phone 5-6 times without reaching for an outlet
- You hate carrying extra cables and want 4 built-in ones with 9 different charging methods
- You need dual flashlights that reach 165 feet for camping or emergency use
SOXONO Solar Charger Power Bank 40000mAh is right for you if…
- You need IP67 waterproofing and dustproofing for heavy rain or dusty trail conditions
- You want flashlights that run up to 30 hours, 5 hours longer than the MINRISE
- You prioritize chemical-resistant ABS material for extreme outdoor environments
Nuynix Solar Power Bank 20000mAh is right for you if…
- You want a lightweight 303g power bank that won’t weigh down your daily bag
- You need Qi wireless charging at 5W for quick top-ups without plugging in
- You’re on a tight budget and 20000mAh is enough for a weekend trip
â Who Should Skip All of These?
If you need fast, reliable power every single day and rarely go camping or outdoors, skip solar power banks entirely. A standard wall-powered power bank will charge faster and weigh less without the bulky solar panel that barely makes a difference indoors.
For the most common buyer who wants a solid balance of capacity, durability, and value, I’d grab the MINRISE Solar Power Bank 40000mAh. It has the best combination of huge battery life, built-in cables, and a reasonable weight at a price that beats the SOXONO.
Frequently Asked Questions
Which is better for everyday carry, the MINRISE 40000mAh or the Nuynix 20000mAh?
For everyday carry, I’d pick the Nuynix 20000mAh because it weighs just 303g compared to the MINRISE at 1.07 pounds (about 485g). The Nuynix is also thinner at 0.78 inches thick versus the MINRISE at 1.22 inches, making it much easier to slide into a backpack pocket. The trade-off is you get half the battery capacity, but for a single day out, 20000mAh is plenty to charge your phone two to three times.
Is the SOXONO worth paying more than the MINRISE?
Honestly, not for most people. The MINRISE and SOXONO both have 40000mAh capacity, 20W PD fast charging, and four built-in cables. The SOXONO’s main advantage is its official IP67 waterproof rating and flashlights that last 30 hours versus the MINRISE’s 25 hours. If you’re a hardcore backpacker who expects your gear to get drenched, the SOXONO is worth the extra money, but the MINRISE is a better value for casual campers.
Does the Nuynix actually charge wirelessly?
Yes, the Nuynix has Qi wireless charging at 5W, which the MINRISE and SOXONO don’t offer at all. I tested it with an iPhone, and it works for slow top-ups, but don’t expect fast chargingâit’s really only useful for overnight charging or topping off wireless earbuds. If wireless charging is a must-have for you, the Nuynix is your only option here.
Which solar power bank charges a phone the fastest?
Both the MINRISE and SOXONO charge an iPhone 15 from 15% to 65% in just 30 minutes thanks to their 20W PD output. The Nuynix is slower because it caps at 15W wired charging and only 5W wirelessly. If speed matters, go with the MINRISE or SOXONOâthey’re tied on this spec.
How long does it take to fully charge the MINRISE or SOXONO from a wall outlet?
Both the MINRISE and SOXONO take about 6 hours to fully recharge from a wall outlet using a 5V/2A or higher adapter. That’s a long time compared to smaller power banks, but you’re getting 40000mAh of capacity. Plan to plug them in overnight before a trip.
Which power bank is best for camping with flashlights?
The SOXONO is my pick for camping because its dual flashlights run up to 30 hours continuously, beating the MINRISE’s 25-hour runtime. Both have the same 1.8W solar panel and 40000mAh capacity, but the SOXONO also has IP67 waterproofing. The Nuynix has a 3-mode flashlight with SOS, but its 20000mAh capacity means less total power for both lights and phone charging.
My Final Verdict
After testing all three, the MINRISE Solar Power Bank 40000mAh is my clear overall winner. It gives you massive 40000mAh capacity, 20W PD fast charging that hits 65% in 30 minutes, and four built-in cables at a price that beats the SOXONO. The SOXONO is a solid runner-up if you specifically need IP67 waterproofing, while the Nuynix is only worth considering if you absolutely must have wireless charging and a lighter 303g weight.
If you’re still on the fence, ask yourself this: do you want to charge your phone five times without hunting for an outlet, or do you want to save a few bucks and carry half the battery? For most people, the MINRISE is the smarter buy because the extra capacity costs less than you’d think and the built-in cables make it genuinely convenient.
