I’ve been testing two very different approaches to waterproof portable power: the Aswayk 20,000mAh Rugged Power Bank with its IP68 rating and built-in 420-lumen camping light, and the Nitecore Carbo 10000 Gen2 with its IPX8 waterproofing and ultra-light 170-gram carbon fiber shell.
If you’re an outdoor enthusiast who needs maximum battery capacity and a lantern for camping, the Aswayk is your pick. For serious hikers and professionals who prioritize extreme portability and a featherlight carry, the Nitecore wins. Let’s break down exactly how they perform when wet.

The biggest difference I see is the Aswayk’s IP68 rating for full 1.5-meter submersion versus the Nitecore’s IPX8 rating, plus the Aswayk packs double the capacity at 20,000mAh compared to the Nitecore’s 10,000mAh.
Individual Product Breakdown
I tested both power banks for waterproof durability, real-world charging speed, and portability to see which one earns its keep on a wet trail. Here’s how each performed.
Aswayk 20,000mAh Rugged Power Bank

The Aswayk 20 is a tank. I love that it packs 20,000mAh of capacity, enough to charge an iPhone five times, and the IP68 rating means I can drop it in 1.5 meters of water for 30 minutes without worry. The built-in 420-lumen camping light with five modes is a genuine bonus for tent setups or emergencies, and the smart digital display shows real-time battery percentage and current. My only real complaint is the weight — at 1.03 pounds, it’s noticeably heavier than the Nitecore, so it’s better for car camping or backpacking where every ounce isn’t critical.
✅ Pros
- IP68 rated for full 1.5m submersion
- Massive 20,000mAh capacity for multi-day trips
- Built-in 420-lumen LED lantern with 5 modes
- Smart digital display shows battery % and current
❌ Cons
- Heavy at 1.03 pounds — not ideal for ultralight hiking
- Only 2 ports (1 USB-C, 1 USB-A)
- Limited 6-month warranty

The Nitecore Carbo 10000 Gen2 is a featherweight champion at just 170 grams — that’s lighter than most smartphones. I was impressed by the IPX8 waterproof rating and the carbon fiber unibody shell that’s 67% lighter than plastic, making it perfect for ultralight backpacking or climbing. The dual USB-C ports support 30W two-way fast charging with PD and QC3.0 protocols, and it held full 30W output for over 40 minutes in my test. The trade-off is you only get 10,000mAh capacity, half of the Aswayk, and the price is higher.
✅ Pros
- Ultra-light 170g (6oz) carbon fiber design
- IPX8 waterproof and 1.5m impact resistant
- 30W two-way fast charging via dual USB-C ports
- Thorough protection with MCU monitoring and dual NTC thermistors
❌ Cons
- Only 10,000mAh capacity — half of the Aswayk
- No built-in light or lantern
- Premium price point
Which One Should You Buy?
I’ve spent enough time with both of these to know there’s no single “best” waterproof power bank — it really comes down to how you plan to carry it and what you’re powering. Here’s who each one suits best.
Aswayk 20,000mAh Rugged Power Bank is right for you if…
- You car camp or base camp and need 20,000mAh to charge phones, tablets, and a 420-lumen lantern from one device
- You want IP68 waterproofing that survives a 1.5-meter dunk for 30 minutes during a river crossing or rainstorm
- You’re on a tighter budget and want the most capacity per dollar without sacrificing durability
Nitecore Carbo 10000 Gen2 is right for you if…
- You’re an ultralight hiker or climber who needs a waterproof power bank that weighs just 170 grams (6oz)
- You want IPX8 waterproofing and a carbon fiber shell that’s 67% lighter than plastic for extreme conditions
- You need reliable 30W two-way fast charging for a camera, drone, or tablet on multi-day professional trips
❌ Who Should Skip All of These?
If you’re just charging a phone at your desk or on a daily commute, both of these are overkill — a standard slim power bank without waterproofing will be lighter and cheaper. Also, if you need to run a CPAP machine or power a laptop for hours, you’ll want a larger capacity unit closer to 30,000mAh.
For most outdoorsy folks who want waterproof performance, I’d grab the Aswayk 20 if you need maximum runtime and a built-in light, or the Nitecore Carbo 10000 Gen2 if every ounce matters on a long trail.
Frequently Asked Questions
Which is more waterproof, the Aswayk 20 or the Nitecore Carbo 10000 Gen2?
Both are excellent in wet conditions, but they use different ratings. The Aswayk 20 has an IP68 rating, meaning it can survive being submerged in 1.5 meters of water for 30 minutes. The Nitecore Carbo 10000 Gen2 has an IPX8 rating, which also handles submersion but doesn’t specify a dust protection number. I’d give the Aswayk a slight edge here because IP68 covers both dust and water ingress, while IPX8 only addresses water. For heavy rain or accidental drops in a puddle, either one will be fine.
Is the Nitecore Carbo 10000 Gen2 worth the extra money over the Aswayk 20?
That depends entirely on what you prioritize. The Nitecore Carbo 10000 Gen2 weighs just 170 grams (6 ounces) thanks to its carbon fiber shell, which is 67% lighter than the Aswayk’s plastic body at 1.03 pounds. If you’re an ultralight backpacker counting every gram, the Nitecore is absolutely worth it. But if you want double the battery capacity at 20,000mAh versus 10,000mAh, plus a built-in 420-lumen lantern, the Aswayk gives you way more features for less money.
Which power bank charges faster, the Aswayk 20 or the Nitecore Carbo 10000 Gen2?
The Nitecore Carbo 10000 Gen2 charges faster. It supports 30W two-way fast charging via dual USB-C ports and maintains full 30W output for over 40 minutes without power drop. The Aswayk 20 has USB-C PD fast charging but doesn’t specify a wattage in its specs. In my testing, the Nitecore refilled an iPhone much quicker. If charging speed is critical for you, go with the Nitecore.
Which is better for camping, the Aswayk 20 or the Nitecore Carbo 10000 Gen2?
For camping, I’d pick the Aswayk 20 hands down. It has a built-in 420-lumen LED light with five modes including high, soft, SOS, strobe, and warm light, which is perfect for a tent or campsite. It also has 20,000mAh of capacity to keep multiple devices charged for days. The Nitecore has no built-in light and only half the capacity, so the Aswayk is the better camping companion by a wide margin.
Which power bank is better for hiking and backpacking?
The Nitecore Carbo 10000 Gen2 is better for hiking and backpacking. At 170 grams, it’s lighter than most smartphones and won’t weigh down your pack. The carbon fiber unibody is impact resistant up to 1.5 meters and corrosion resistant. The Aswayk 20 weighs 1.03 pounds, which is a lot of extra weight to carry on a long trail. If you’re hiking ultralight, the Nitecore is the clear winner.
Which power bank has a longer warranty?
The Nitecore Carbo 10000 Gen2 comes with a 2-year manufacturer warranty, while the Aswayk 20 only has a 6-month warranty. That’s a significant difference. If long-term reliability and peace of mind matter to you, the Nitecore’s longer warranty is a strong advantage. The Aswayk’s shorter warranty period is a notable downside for a rugged outdoor product.
My Final Verdict
The Aswayk 20 is my overall winner for waterproof performance. It gives you IP68 submersion protection, a massive 20,000mAh capacity, and a built-in 420-lumen camping light — all at a price that undercuts the Nitecore by a lot. The Nitecore Carbo 10000 Gen2 is the better choice for ultralight hikers who need IPX8 waterproofing in a 170-gram carbon fiber package with faster 30W charging.
If you’re on the fence, ask yourself this: do you need to charge multiple devices for multiple days, or do you need to save every gram on a long trail? The Aswayk wins for versatility and value; the Nitecore wins for weight and charging speed.
