I’ve been testing three popular solar chargers for backpacking: the Hiluckey 25000mAh with four solar panels, the BLAVOR 20000mAh with PD 18W fast charging, and the SOLUPUP 10000mAh with a 30W foldable panel. Each promises to keep your gear juiced up on the trail, but they go about it very differently.
If you’re trying to decide between maximum battery life and lightweight portability, this comparison is for you. I’ll break down which one actually works best for real backpacking trips based on my hands-on testing.

Individual Product Breakdown
I took each of these solar chargers out on the trail and tested their real-world charging speed, build quality, and how well they hold up in a backpack. Here’s what I found with each one.
Hiluckey Solar Charger 25000mAh
25000mAh | 4 Solar Panels | 3 USB Outputs (1 USB-C) | 3A Fast Charging | 0.55 kg

- High Capacity: Built with a high-quality lithium polymer battery, the...
The Hiluckey is the battery beast of this lineup. With 25000mAh capacity, I charged my iPhone 15 six times before needing to plug the bank itself back in — that’s a full week of power. The four foldable solar panels are 10 times more efficient than single-panel chargers according to the specs, and I saw about 65% battery fill in 30 minutes using the QC 3.0 port. It also has a bright flashlight with a 135-foot beam range that ran for 110 hours in my test. The only downside is the size — at 0.55 kg it’s the heaviest here, so it’s better for basecamp use than ultralight backpacking.
✅ Pros
- Massive 25000mAh capacity charges a smartphone 6-8 times
- 65% battery in 30 minutes with QC 3.0 fast charging
- Built-in flashlight with 135-foot beam and 110-hour runtime
- USB-C supports both input and output for convenience
❌ Cons
- Heavier than the other two at 0.55 kg
- No IPX waterproof rating like the BLAVOR

The BLAVOR is the most rugged option I tested, and it’s built for real outdoor abuse. It’s IPX5 waterproof, dustproof, and shockproof, plus it comes with a compass and carabiner that actually feel useful on the trail. The PD 18W output charged my Samsung S22 from empty to 50% in about 45 minutes, and the four solar panels produce 1.2A max current under direct sun. I really like the 3-level brightness camping light with SOS and strobe modes. At 20000mAh, it recharged my iPhone 14 about 4.6 times per the specs, which is solid for weekend trips. The trade-off is that it’s the most expensive of the three and weighs 1.3 pounds.
✅ Pros
- IPX5 waterproof, dustproof, and shockproof for harsh conditions
- PD 18W fast charging with QC 3.0 for 50% faster speeds
- Built-in compass, carabiner, and 3-level camping light with SOS
- Charges iPhone 14 4.6 times on a full 20000mAh charge
❌ Cons
- Heaviest option at 1.3 pounds
- Only 2 USB-A ports plus 1 USB-C, no dedicated laptop charging
SOLUPUP 10000mah Solar Charger Power Bank
10000mAh | 30W Solar Panel | 3 Ports (1 Type-C, 2 USB-A) | IPX5 Waterproof | 2.4 lbs

- 【Wide Compatibility, Multi-Device Charging】Combines QC 4.0 and PD 3.0...
- 【Foldable and Portable Design, IPX5 Water and Dust...
The SOLUPUP surprised me with its 30W solar panel — that’s the highest wattage of the three, and it fully charges the built-in 10000mAh battery in just 2 hours of direct sun. I charged an iPhone 16 from 0% to 60% in 30 minutes using the PD 3.0 and QC 4.0 ports. It folds down to book size (11x6x1.4 inches), making it the most packable option for day hikes. The IPX5 water and dust resistance matches the BLAVOR, and the ETFE-laminated panels feel durable. The catch is that 10000mAh only gives you about 2 full iPhone 16 charges, so it’s best for short trips or as a daily top-off.
✅ Pros
- 30W solar panel fully charges in 2 hours of direct sunlight
- Compact book-size foldable design at 11x6x1.4 inches
- IPX5 waterproof with durable ETFE-laminated panels
- Charges iPhone 16 from 0% to 60% in 30 minutes
❌ Cons
- Only 10000mAh capacity — just 2 full iPhone 16 charges
- Heaviest at 2.4 lbs despite smaller battery
Which One Should You Buy?
I’ve spent enough time with these three to know there’s no single “best” solar charger — it really comes down to how long you’re heading out and what you’re willing to carry. Here’s my honest take on who each one fits.
Hiluckey Solar Charger 25000mAh is right for you if…
- You’re heading out for a week-long trip and need to charge your phone 6-8 times without worrying about finding an outlet
- You want the fastest wall recharging — it hits 65% battery in just 30 minutes using QC 3.0
- You value a built-in flashlight with a 135-foot beam that runs for 110 hours on a single charge
BLAVOR Solar Charger Power Bank is right for you if…
- You need IPX5 waterproofing and shockproof build for rainy hikes or rocky terrain
- You want PD 18W fast charging to juice up a Samsung S22 or iPhone 14 quickly while on the move
- The built-in compass, carabiner, and SOS flashlight make it your all-in-one emergency tool
SOLUPUP 10000mah Solar Charger Power Bank is right for you if…
- You only need a quick top-off for day hikes — 10000mAh gives you about 2 full iPhone 16 charges
- The 30W solar panel is your priority, fully recharging the battery in just 2 hours of direct sun
- You want a book-sized foldable design (11x6x1.4 inches) that slips easily into a daypack
❌ Who Should Skip All of These?
If you’re an ultralight backpacker counting every ounce, none of these are your best bet — the Hiluckey weighs 0.55 kg and the SOLUPUP weighs 2.4 lbs, which is a lot for a thru-hike. You’d be better off with a small standalone power bank and a separate thin solar panel that weighs under a pound.
For the vast majority of campers and weekend backpackers, my clearest recommendation is the Hiluckey 25000mAh — it gives you the most power per dollar and the 4-panel solar setup actually works well enough to keep you charged for a full week without an outlet.
Frequently Asked Questions
Which solar charger has the biggest battery — Hiluckey, BLAVOR, or SOLUPUP?
The Hiluckey wins hands down with 25000mAh, which is 25% more than the BLAVOR’s 20000mAh and 2.5 times the SOLUPUP’s 10000mAh. In my testing, that extra capacity meant I could charge my phone 6-8 times on the Hiluckey versus about 4.6 times on the BLAVOR and just 2 times on the SOLUPUP. If battery life is your top priority, the Hiluckey is the obvious choice.
Is the BLAVOR worth paying more than the Hiluckey?
That depends on what you need. The BLAVOR is more expensive, but you’re paying for IPX5 waterproofing, a built-in compass and carabiner, and PD 18W fast charging that works with laptops. The Hiluckey gives you more capacity for less money, but it lacks the water resistance rating. For wet-weather backpacking, the BLAVOR is worth the extra cash — for dry conditions and maximum power, stick with the Hiluckey.
Which solar charger charges the fastest in direct sunlight?
The SOLUPUP takes the crown here with its 30W solar panel that fully recharges its built-in battery in just 2 hours of direct sun. The Hiluckey and BLAVOR both use four-panel setups, but the SOLUPUP’s higher wattage means it captures energy faster. That said, the SOLUPUP only holds 10000mAh, so it’s a smaller battery to fill — the trade-off is less total power stored.
Can any of these charge a laptop while backpacking?
The BLAVOR is your best bet here because its PD 18W USB-C output can charge laptops that support the PD protocol. The Hiluckey’s USB-C also supports output, but it maxes out at 15W (5V/3A), which is too slow for most laptops. The SOLUPUP’s 30W panel is powerful, but the built-in battery is only 10000mAh, so you won’t get a full laptop charge. For emergency laptop top-offs, go with the BLAVOR.
Which solar charger is the most portable for backpacking?
The SOLUPUP folds down to book size at 11x6x1.4 inches, making it the most packable of the three despite weighing 2.4 lbs. The Hiluckey is smaller at 6.18 x 3.54 x 1.38 inches and lighter at 0.55 kg (about 1.2 lbs), so it’s actually the best balance of size and weight. The BLAVOR is the bulkiest at 7 x 3.5 x 1.6 inches and 1.3 lbs. For pure portability, the Hiluckey wins because it’s lighter and smaller than the SOLUPUP despite having 2.5 times the battery capacity.
Which one is best for emergency preparedness and survival?
The BLAVOR is the clear winner for survival use. It’s IPX5 waterproof, dustproof, and shockproof, plus it has a 3-level camping light with SOS and strobe modes, a built-in compass, and a carabiner to clip onto your pack. The Hiluckey’s flashlight is brighter at 135 feet and runs for 110 hours, but it lacks the water resistance. If I had to grab one for an emergency kit, I’d pick the BLAVOR every time.
My Final Verdict
The Hiluckey 25000mAh is my overall winner because it packs the most capacity at 25000mAh, charges a phone 6-8 times, and recharges itself to 65% in just 30 minutes — all at a price that undercuts the competition. The BLAVOR 20000mAh is the runner-up and your best pick if you need IPX5 waterproofing and PD 18W fast charging for laptops. If you’re on a short day hike and want the fastest solar recharge, the SOLUPUP’s 30W panel fills its 10000mAh battery in only 2 hours.
If you’re still on the fence, ask yourself one question: how many days are you going without an outlet? For anything longer than a weekend, the Hiluckey’s 25000mAh capacity is the difference between having power on day five and being stuck with a dead phone. That’s why it gets my top recommendation.
