I’ve been testing two popular solar power banks for airline travel: the Luvknit 20000mAh and the Saraupup 20000mAh. Both are airline-approved portable chargers with built-in cables, but they take very different approaches to keeping your devices juiced up on the go.
If you’re a frequent flyer or outdoor enthusiast trying to decide between rugged durability and wireless convenience, this comparison is for you. I’ll break down exactly where each power bank shines so you can pick the one that fits your travel style.

Individual Product Breakdown
I tested both power banks for build quality, charging speed, and real-world travel use. Here’s how each one performed.

The Luvknit is the tougher of the two by a long shot. With an IP67 waterproof rating and a flame-retardant ABS+PC shell, this thing can handle rain, drops, and dusty campsites without breaking a sweat. I love that it charges up to 6 devices at once and has a built-in 3-in-1 cable system (USB-C, Lightning, Micro-USB) so you don’t have to carry extra cords. The 15W fast charging got my iPhone from 15% to 65% in about 30 minutes, just as advertised. My only real complaint is that it takes a full 10 hours to recharge via wall charger, so plan ahead.
β Pros
- IP67 waterproof and dustproof β tougher than the Saraupup’s IPX5 rating
- Charges up to 6 devices simultaneously with built-in cables
- 3-mode LED flashlight (Strong Light, Strobe, SOS) for emergencies
- Lighter at 0.91 pounds compared to the Saraupup’s 1.5 pounds
β Cons
- Takes 10 hours to fully charge via wall outlet
- No wireless charging option like the Saraupup offers

The Saraupup is the gadget-lover’s choice with wireless charging and four foldable solar panels. I was impressed that it can charge an iPhone 16 three to four times on a full battery, and the 5V/3A fast charging hit 65% in just 30 minutes through the USB-C cable. The dual LED flashlights are bright enough to illuminate up to 15 meters, and the included compass carabiner is a nice touch for hikers. However, at 1.5 pounds it’s noticeably heavier than the Luvknit, and the IPX5 water resistance isn’t as rugged as the Luvknit’s IP67 rating. The solar charging also takes 12-15 hours of direct sunlight for a full charge, so don’t rely on it as your primary power source.
β Pros
- Wireless charging compatible with iPhone 15/14/13 series and Galaxy S24/S23
- 4 foldable solar panels with included compass carabiner for hiking
- Dual LED flashlights with 15-meter range and SOS mode
- Lifetime warranty from Saraupup
β Cons
- Heavier at 1.5 pounds versus Luvknit’s 0.91 pounds
- IPX5 splash-proof only, not fully submersible like the Luvknit’s IP67
- Solar charging takes 12-15 hours of direct sunlight for a full charge
Which One Should You Buy?
After testing both power banks side by side, I can tell you there’s no universal winner β the right choice depends entirely on where you’re traveling and what you value most. Here’s how to figure out which one fits your trip.
Luvknit Solar Power Bank 20000mAh is right for you if…
- You need maximum durability for rough travel β the IP67 waterproof rating means it survives drops, dust, and full submersion.
- You’re traveling with a group and need to charge up to 6 devices at once with the built-in cables.
- You want a lighter pack β at 0.91 pounds it’s almost half the weight of the Saraupup.
Saraupup Solar Power Bank 20000mAh is right for you if…
- You want wireless charging for your iPhone 15 or Galaxy S24 β just place your phone on the pad and go.
- You’re a hiker who will actually use the 4 solar panels and compass carabiner during long treks.
- You prefer having dual LED flashlights that illuminate up to 15 meters for nighttime camping.
β Who Should Skip All of These?
If you’re a backpacker who needs to rely on solar charging as your main power source, skip both of these β the 12-15 hour solar recharge time on the Saraupup and the lack of efficient solar on the Luvknit mean you’re better off with a dedicated high-wattage solar panel setup. Likewise, if you only need to charge one phone and want the smallest possible battery, look at a 10000mAh power bank instead.
For most travelers, I’d grab the Luvknit β it’s lighter, tougher, and charges more devices, which is exactly what you want when you’re bouncing between airports and campsites.
Frequently Asked Questions
Which is better for airline travel, the Luvknit or Saraupup?
I’d give the edge to the Luvknit for flying. It’s lighter at 0.91 pounds compared to the Saraupup’s 1.5 pounds, and it charges up to 6 devices at once through built-in cables β perfect for keeping your phone, tablet, and earbuds powered during layovers. Both are airline-approved at 20000mAh, but the Luvknit’s smaller footprint makes it easier to pack in a carry-on.
Is the Saraupup worth the extra money over the Luvknit?
Only if you actually need wireless charging or plan to use the solar panels. The Luvknit is the better value for most people because it’s more durable with IP67 waterproofing and charges more devices simultaneously. The Saraupup costs more and adds wireless charging and a compass carabiner, but you’re getting heavier build and less rugged water protection at IPX5.
Which power bank is more waterproof for outdoor use?
The Luvknit wins this hands down with its IP67 rating, meaning it’s fully dustproof and can survive submersion in water. The Saraupup only has IPX5 splash-proof protection, which handles rain and splashes but won’t survive being dropped in a stream. If you camp in wet conditions, go with the Luvknit.
Can the solar panels on these actually charge the battery?
Technically yes, but don’t count on it as your main power source. The Saraupup’s 4 solar panels need 12-15 hours of direct sunlight for a full charge, and the Luvknit’s solar panel is even less efficient. I treat the solar as a backup trickle charge for emergencies β you’ll want to charge both via wall outlet before your trip.
How many times can each power bank charge my iPhone?
The Luvknit provides up to 2.5 full charges for an iPhone 15 with its 20000mAh capacity, while the Saraupup claims 3-4 charges for an iPhone 16. Both will easily get you through a weekend trip, but the Saraupup has a slight edge in real-world phone charging due to its higher efficiency lithium-polymer cells.
Which one charges faster?
They’re very close on speed. The Luvknit delivers 15W fast charging and gets an iPhone from 15% to 65% in about 30 minutes. The Saraupup hits 5V/3A (15W) through USB-C and reaches 65% in the same 30 minutes. For wall charging, expect around 10 hours to fully recharge the Luvknit, while the Saraupup doesn’t list a specific wall charge time.
My Final Verdict
The Luvknit Solar Power Bank 20000mAh is my clear winner for airline travel. It’s lighter at 0.91 pounds, tougher with IP67 waterproofing, and charges up to 6 devices at once through built-in cables β everything a traveler needs. The Saraupup is a solid runner-up for gadget lovers who want wireless charging and don’t mind the extra weight.
If you’re still on the fence, ask yourself this: do you need wireless charging and solar panels, or do you want a lighter, more durable power bank that can handle rain and rough handling? For most flyers, the Luvknit’s rugged build and multi-device charging make it the smarter pick.
