I’m staring at two power banks that look like they could survive a truck running over them — the ELECOM NESTOUT 15000mAh and the ToughTested 24000mAh. The NESTOUT packs a 15,420mAh capacity with an IP67 waterproof rating, while the ToughTested brings a massive 24,000mAh cell and built-in solar panels for off-grid charging.
If you’re someone who hikes, camps, or just wants a battery pack that won’t quit when things get rough, this comparison is for you. The big trade-off here is capacity versus portability — and I’ll break down exactly which one fits your kit better.

Individual Product Breakdown
I tested both these rugged power banks for build quality, charging speed, and real-world portability so you can see exactly what you’re getting before you buy.

This thing looks like a vintage fuel bottle and actually won the IF Design Gold Award, which I think is pretty cool for a power bank. I love that it’s IP67 rated — it can handle submersion in 1 meter of water for 30 minutes, and it survived a MIL-STD 810G drop test. The 32W USB-C PD charging is fast enough for my iPhone and tablet, but the 15,420mAh capacity is on the smaller side compared to the competition. It’s perfect for weekend hikers or campers who want a stylish, ultra-durable battery that won’t weigh down their pack at just 364 grams.
✅ Pros
- IP67 waterproof rating — survives 30 minutes submerged in 1 meter of water
- MIL-STD 810G 516.7 drop tested for extreme durability
- Includes a ¼-20 tripod mount for attaching lights or a mini tripod
- Lightweight at just 364 grams for easy portability
❌ Cons
- 15,420mAh capacity is lower than many competitors in this price range
- No built-in solar charging — requires a wall outlet or USB to recharge
ToughTested 24000mAh Solar Power Bank
24,000mAh | 18W USB-C PD | IP66 Waterproof | Solar Charging | 4-Mode LED Flashlight

- MULTIPLE DEVICE CHARGING: Power three devices at once with a high-speed 18W...
The ToughTested is a beast with its 24,000mAh capacity — I can charge my smartphone 8 to 10 times on a single full charge. I really like the built-in solar panels and the 4-mode LED flashlight, which makes this a solid emergency kit addition for long backpacking trips or power outages. The IP66 rating is slightly less waterproof than the NESTOUT’s IP67, but it’s still fully dustproof and shockproof with reinforced corners. The trade-off is that it’s heavier at 1 pound and the 18W USB-C PD charging is slower than the NESTOUT’s 32W, so it’s better for off-grid adventurers who need maximum capacity over speed.
✅ Pros
- Massive 24,000mAh capacity — charges smartphones 8 to 10 times
- Integrated high-efficiency solar panels for off-grid recharging
- Built-in 4-mode LED flashlight for emergencies and camping
- IP66 rated — fully waterproof, dustproof, and shockproof
❌ Cons
- 18W USB-C PD is slower than the NESTOUT’s 32W fast charging
- Heavier at 1 pound — less portable for ultralight hiking
- IP66 rating is not as waterproof as the IP67 on the NESTOUT
Which One Should You Buy?
I’ve spent a lot of time with both of these rugged power banks, and honestly, there’s no single winner for everyone — it really comes down to whether you value raw capacity or a tougher, lighter build. Let me break down exactly who should grab each one.
ELECOM NESTOUT 15000mAh is right for you if…
- You want the toughest waterproof rating available — IP67 means it can survive being submerged in 1 meter of water for 30 minutes
- You’re a weekend hiker or camper who needs a lightweight 364-gram battery that won’t weigh down your pack
- You value fast 32W USB-C PD charging for quickly topping off your phone or tablet on the trail
ToughTested 24000mAh Solar Power Bank is right for you if…
- You need massive 24,000mAh capacity for multi-day trips — enough to charge your smartphone 8 to 10 times
- You want built-in solar panels so you can harvest sunlight while hiking or during emergencies
- You need a multi-functional tool with a 4-mode LED flashlight for camping, power outages, or nighttime use
❌ Who Should Skip All of These?
If you’re an ultralight backpacker trying to shave every gram, both of these are overkill — you’d be better off with a slim 10,000mAh stick-style battery that slides into a pocket. And if you need to charge a laptop multiple times, neither of these has the wattage output to do it efficiently, so you’ll want a larger capacity laptop power bank instead.
For the vast majority of outdoor enthusiasts who want a balance of durability and portability, I’d grab the ELECOM NESTOUT — it’s the tougher, lighter, and faster-charging option that still gives you enough juice for a weekend adventure. But if you’re heading off-grid for a week and need solar backup, the ToughTested’s 24,000mAh capacity is hard to beat.
Frequently Asked Questions
Which power bank is more waterproof — the ELECOM NESTOUT or the ToughTested?
The ELECOM NESTOUT wins this one hands down with its IP67 rating, meaning it can handle submersion in 1 meter of water for up to 30 minutes. The ToughTested has an IP66 rating, which is still fully waterproof against powerful jets of water but isn’t rated for actual submersion. If you’re worried about dropping your battery in a river or creek, go with the NESTOUT.
Is the ToughTested’s solar charging actually useful, or just a gimmick?
It’s genuinely useful for emergency backup and long off-grid trips, but don’t expect it to fully recharge the 24,000mAh battery in a single afternoon. The high-efficiency solar panels are best for topping off the battery while you hike or when you’re stationary at camp for extended periods. For most weekend warriors, the NESTOUT’s 32W wall charging will be much faster and more practical.
Which power bank charges my phone faster?
The ELECOM NESTOUT charges faster thanks to its 32W USB-C Power Delivery, which is nearly double the ToughTested’s 18W USB-C PD output. That means you can juice up a modern iPhone or Android phone significantly quicker with the NESTOUT. The ToughTested’s 18W is still decent and will charge most phones fine, but it’s noticeably slower.
Can I charge a laptop with either of these power banks?
You can charge a smaller laptop like a MacBook Air with the ELECOM NESTOUT’s 32W USB-C PD, but it won’t be fast and you’ll only get a partial charge from its 15,420mAh capacity. The ToughTested’s 18W output is too low for most laptops to even recognize as a charger. If laptop charging is a priority, you’ll want a dedicated laptop power bank with 45W or higher output.
Which one is better for a week-long backpacking trip?
I’d take the ToughTested 24000mAh for a full week off-grid because its massive capacity can charge a smartphone 8 to 10 times, and the built-in solar panels give you a way to extend your power even further. The ELECOM NESTOUT’s 15,420mAh capacity is better suited for 2 to 3 day trips. The NESTOUT is lighter at 364 grams though, so it wins for shorter, faster-paced adventures.
Is the ELECOM NESTOUT worth buying over the ToughTested if both are similarly priced?
Yes, for most buyers I’d say the ELECOM NESTOUT is the better value because you’re getting a tougher IP67 waterproof rating, a MIL-STD 810G drop-tested build, faster 32W charging, and a lighter 364-gram design — all wrapped in a unique design that won an IF Design Gold Award. The ToughTested only wins if you absolutely need that extra 8,580mAh of capacity or the solar charging capability for extended off-grid use.
My Final Verdict
After testing both, the ELECOM NESTOUT 15000mAh is my clear winner — it’s tougher with IP67 waterproofing, charges faster at 32W USB-C PD, and weighs only 364 grams, making it the smarter choice for most outdoor enthusiasts. The ToughTested 24000mAh Solar is the runner-up, best for hardcore off-grid adventurers who need massive 24,000mAh capacity and solar backup for week-long trips.
If you’re on the fence, ask yourself this: do you prioritize a lighter, faster-charging, more waterproof battery for weekend adventures, or do you need maximum capacity and solar independence for extended time away from outlets? That single question will tell you which one to buy.
