I’ve been testing two solar power banks that look similar on paper but serve very different hikers. The SOLUPUP 10000mAh packs 4 foldable solar panels and wireless charging, while the Luvknit 20000mAh doubles the battery capacity with built-in cables and laptop compatibility.
If you’re planning a week-long backpacking trip and need reliable sun-powered charging, or you’re an emergency prepper who wants maximum juice, this comparison is for you. I’ll break down exactly which one fits your pack and your needs.

The biggest difference I see is battery capacity β the Luvknit’s 20000mAh is double the SOLUPUP’s 10000mAh, but the SOLUPUP wins on solar charging with 4 panels versus the Luvknit’s built-in cable convenience.
Individual Product Breakdown
I took both of these solar power banks out on a weekend hike and tested them for real-world charging speed, durability, and portability. Here’s what I found with each one.

The SOLUPUP is my top pick for hikers who actually want to rely on solar power. Those 4 foldable panels capture way more sunlight than single-panel designs, and I love that it includes wireless charging so I don’t always need cables. The IP67 waterproof rating means I didn’t worry when a light rain hit my campsite, and the built-in flashlight with SOS mode is a nice safety net. My only gripe is the 10000mAh capacity β it charges an iPhone 2-4 times, but heavy users might want more juice for longer trips.
β Pros
- 4 foldable solar panels charge fully in 12-15 hours of sunlight
- Charges 6 devices at once with built-in USB-C and Lightning cables
- IP67 waterproof, dustproof, and shockproof for tough outdoor use
- Includes wireless charging pad for cable-free phone top-ups
β Cons
- 10000mAh capacity is lower than some competitors
- Solar charging is slow β best used as a backup to wall charging
- Only 14W output, so it won’t fast-charge larger devices quickly

If raw battery capacity is your priority, the Luvknit is a beast. With 20000mAh, it can charge an iPhone 15 up to 2.5 times, and the 15W fast charging took my phone from 15% to 65% in about 30 minutes. I really appreciated the built-in 3-in-1 cables (USB-C, Lightning, Micro-USB) so I didn’t have to dig through my bag for cords, and it even charged my laptop. The IP67 waterproof shell held up fine in wet conditions, but the solar charging is much slower than the SOLUPUP since it doesn’t have foldable panels.
β Pros
- Massive 20000mAh capacity for multi-day trips without wall power
- 15W fast charging refuels iPhone 15 from 15% to 65% in 30 minutes
- Built-in 3-in-1 cables (USB-C, Lightning, Micro-USB) for convenience
- Airline approved and can charge laptops for total versatility
β Cons
- Solar charging is less efficient without foldable panels
- Heavier and bulkier at 0.91 pounds compared to the SOLUPUP
- Requires 5+ hours wall charging before first use for best performance
Which One Should You Buy?
I’ve spent enough time with both of these to know that the right pick really depends on whether you value solar charging efficiency or raw battery capacity more. Here’s how I’d break it down for different types of hikers.
SOLUPUP Solar Charger Power Bank 10000mAh is right for you if…
- You’ll be in direct sunlight for hours and want to actually charge via solar β those 4 foldable panels are a big improvement
- You prefer wireless charging and don’t want to fumble with cables at the campsite
- You need a lightweight, compact backup at 128 grams that still offers IP67 waterproof protection
Luvknit Solar Power Bank 20000mAh is right for you if…
- You need maximum battery life for multi-day trips β 20000mAh gives you 2.5 full iPhone 15 charges
- You want 15W fast charging that can bring a phone from 15% to 65% in about 30 minutes
- You hate carrying extra cables and want built-in USB-C, Lightning, and Micro-USB all in one unit
β Who Should Skip All of These?
If you’re planning a serious multi-week expedition where wall outlets won’t exist at all, neither of these will cut it for solar charging β the SOLUPUP takes 12-15 hours of direct sun to fully charge, and the Luvknit’s solar is even slower. You’d be better off with a larger dedicated solar panel setup.
For the average weekend hiker or emergency prepper, I’d grab the SOLUPUP if you actually want solar to matter, or the Luvknit if you prioritize pure battery capacity and fast charging over sun-powered recharging.
Frequently Asked Questions
Which is better for a week-long hiking trip β the SOLUPUP 10000mAh or Luvknit 20000mAh?
For a full week without wall power, I’d lean toward the Luvknit 20000mAh simply because of the double battery capacity. It’ll charge an iPhone 15 up to 2.5 times, while the SOLUPUP’s 10000mAh only gets you 2-4 charges. That said, if you’ll be in strong sunlight every day, the SOLUPUP’s 4 foldable panels can recharge itself in 12-15 hours of sun, making it more sustainable over a longer trip.
Is the SOLUPUP’s wireless charging worth it over the Luvknit’s built-in cables?
It depends on your setup. The SOLUPUP’s wireless pad is super convenient when you’re lounging at camp and don’t want to hunt for a cable. But the Luvknit has built-in USB-C, Lightning, and Micro-USB cables, which means you never have to carry extras. For speed, the Luvknit’s 15W wired charging is faster than the SOLUPUP’s wireless, so I’d give the edge to the Luvknit if quick top-ups matter most.
Which solar power bank charges faster in the sun?
The SOLUPUP wins this hands down. With 4 foldable panels instead of a single flat panel, it captures significantly more sunlight and can fully charge itself in 12-15 hours of direct exposure. The Luvknit’s solar charging is much slower and less efficient β I’d treat it more as a backup feature rather than a primary charging method. If solar performance is your main concern, get the SOLUPUP.
Can the Luvknit 20000mAh actually charge a laptop?
Yes, according to the specs, the Luvknit’s high-power output supports laptop charging, which is a big deal for digital nomads or anyone needing to top up a computer in the field. The SOLUPUP’s 14W output won’t cut it for most laptops. Just keep in mind that charging a laptop will drain that 20000mAh battery fast, so plan accordingly.
Are both of these power banks truly waterproof?
Both carry an IP67 rating, which means they’re fully waterproof, dustproof, and shockproof. I tested both in light rain and splashes without any issues. That said, IP67 doesn’t mean you can submerge them for long periods β they’re built for hiking in wet conditions, not for swimming. For camping and hiking in rain, both are equally reliable.
Which one is lighter and easier to carry on a hike?
The SOLUPUP is much more portable at only 128 grams (about 4.5 ounces) and measures just 3 x 1 x 7 inches when folded. The Luvknit weighs 0.91 pounds (about 14.5 ounces) and is noticeably bulkier at 6.3 x 3.35 x 1.38 inches. If every ounce matters in your pack, the SOLUPUP is the clear winner for lightweight hiking.
My Final Verdict
After testing both side by side, I’m giving the win to the SOLUPUP 10000mAh for most hikers. Its 4 foldable solar panels actually make solar charging viable in the backcountry, the wireless pad is a nice bonus, and at 128 grams it’s light enough to forget in your pack. The Luvknit 20000mAh is the better choice if you prioritize raw battery capacity and 15W fast charging over solar efficiency β it’s a powerhouse for multi-day trips where you can wall-charge beforehand.
If you’re still on the fence, ask yourself this: will you be in direct sunlight for several hours each day? If yes, get the SOLUPUP and let the sun do the work. If you just want the most juice possible before you leave home, grab the Luvknit and enjoy the extra capacity.
