I’ve been testing two very different solar power banks for camping and hiking β the Kepswin Solar Charger 20 with its 20,000mAh capacity and the massive YELOMIN 38800mAh unit.

If you’re torn between a compact all-in-one charger and a high-capacity beast that can power your devices for days, this comparison breaks down exactly who should buy which. I’ll walk you through the real-world trade-offs so you can make the right call.

Individual Product Breakdown
I spent time with both solar chargers to see how they handle real-world camping and hiking conditions. Here’s what I found about each one.
Kepswin Solar Charger 20
20000mAh | 4 built-in cables | 3 ports | Dual flashlight | 5.9 x 3.1 x 0.78 inches

The Kepswin is the most convenient solar charger I’ve tested for everyday outdoor use. I love that it comes with 4 built-in cables (Type-C, Lightning, Micro USB, and a USB-A input cable) so I never have to dig through my bag for a cord. The 20000mAh capacity is enough to charge my phone about four times, and the 3 ports plus the cables let me power up 6 devices simultaneously β perfect for group camping trips. The dual flashlight with SOS and strobe modes is genuinely bright, and the waterproof ABS+PC housing with anti-fall silicone corners makes it feel tough enough for a backpack. My only real complaint is that at 3.7 stars from only 11 reviews, it’s not as proven as some competitors.
β Pros
- 4 built-in cables mean no extra cords to carry
- Ultra-compact at only 5.9 inches long and 0.78 inches thick
- Waterproof, dustproof, and shockproof with anti-fall silicone corners
- Dual flashlight with SOS and strobe modes for emergencies
β Cons
- Only 3.7 stars from just 11 reviews β not much user feedback
- 20000mAh is modest compared to larger capacity options
YELOMIN Solar Charger
38800mAh | 3 outputs | 2 flashlights | Compass | 7.48 x 4.21 x 1.18 inches
- γ High-Quality Portable Solar Chargerγ: The 38800mAh solar bank is made...
- γ3 Outports Highly Compatible with Multiple Devices γ: The solar phone...
- γTwo Different Charging Methods γ: 38800mAh External battery charger...
The YELOMIN is a capacity monster that I’d grab for a week-long camping trip where I won’t see a wall outlet. Its 38800mAh battery is nearly double the Kepswin’s, and that shows in the 4.4-star rating from 410 reviews β people clearly trust this thing. I like the 2 bright LED flashlights with SOS and strobe modes, plus the built-in compass is a nice touch for navigation. The 3 USB outputs push 5V/2.4A each, so I can charge three phones at full speed at the same time. On the downside, it’s a chunky 7.48 inches long and 1.18 inches thick, and YELOMIN themselves admit solar charging only gives a trickle current β so don’t rely on the sun alone.
β Pros
- Massive 38800mAh capacity for extended off-grid trips
- 4.4 stars from 410 reviews β well-tested and trusted
- 2 bright LED flashlights with SOS and strobe plus a compass
- 3 USB outputs at 5V/2.4A for fast simultaneous charging
β Cons
- Bulky at 7.48 x 4.21 x 1.18 inches β not pocket-friendly
- Solar charging is very slow and only provides trickle current
- No built-in cables β you’ll need to carry your own
Which One Should You Buy?
I’ve tested both of these solar chargers pretty thoroughly, and honestly, the “best” one depends entirely on whether you value compact convenience or raw battery capacity more. Here’s how I’d break it down for different campers and hikers.
Kepswin Solar Charger 20 is right for you if…
- You hate carrying extra charging cables β the 4 built-in cables (Type-C, Lightning, Micro USB, USB-A) cover every device you own
- You want a compact power bank for day hikes at just 5.9 x 3.1 x 0.78 inches that fits in a jacket pocket
- You need to charge multiple devices at once β up to 6 devices with the 3 ports and 4 cables working together
YELOMIN Solar Charger is right for you if…
- You’re going on a multi-day camping trip and need the massive 38800mAh capacity to keep phones, cameras, and tablets alive
- You want a proven product with 410 reviews and a solid 4.4-star rating behind it
- You value extra safety features like 2 bright LED flashlights with SOS mode and a built-in compass for navigation
β Who Should Skip All of These?
If you need a power bank that actually relies on solar charging as a primary source, skip both of these β YELOMIN flat-out admits solar only provides a trickle current, and neither unit has a large enough solar panel to charge quickly. You’d be better off with a dedicated large solar panel setup and a standard power bank.
For most campers and hikers, I’d recommend the Kepswin Solar Charger 20 β the built-in cables and compact size make it the smarter everyday choice. But if you’re planning a week-long off-grid trip and need maximum battery life, the YELOMIN’s 38800mAh capacity is the clear winner.
Frequently Asked Questions
Which solar charger has a bigger battery β Kepswin or YELOMIN?
The YELOMIN has nearly double the capacity at 38800mAh compared to the Kepswin’s 20000mAh. If you’re going on a multi-day trip and need to charge phones, tablets, and cameras multiple times, the YELOMIN is the clear choice. But that extra power comes with size β the YELOMIN is 7.48 inches long versus the Kepswin’s more pocket-friendly 5.9 inches.
Which one is better for backpacking and hiking?
I’d pick the Kepswin for backpacking every time. It’s way more compact at 5.9 x 3.1 x 0.78 inches and weighs just 200 milligrams, plus the 4 built-in cables mean you don’t need to carry any extra cords. The YELOMIN’s 7.48-inch length and extra bulk make it better suited for base camp or car camping where weight isn’t as critical.
Does the Kepswin or YELOMIN charge faster?
The YELOMIN has a slight edge here with its 5V/2.4A USB outputs, which can charge three smartphones at full speed simultaneously. The Kepswin also supports fast charging through its USB-C port, but its total 20000mAh capacity means it’ll drain faster if you’re pushing 6 devices at once. For most people, both will charge a phone at a similar speed β just pick based on how many devices you need to power.
Which solar charger has better flashlights?
Both units have dual flashlights with SOS and strobe modes, so they’re pretty evenly matched for emergency use. The Kepswin lets you switch between normal torch, SOS, and strobe modes with a short button press, while the YELOMIN adds a built-in compass for navigation. If you need a compass anyway, the YELOMIN saves you from carrying one separately.
Is the YELOMIN worth the extra size over the Kepswin?
It depends on what you need. If you’re going on a 5-day camping trip with no power access, the YELOMIN’s 38800mAh capacity is absolutely worth the extra bulk. But if you’re doing day hikes or weekend trips where you can recharge at night, the Kepswin’s 20000mAh is plenty and the compact size is a huge advantage. The YELOMIN also has a proven track record with 410 reviews and a 4.4-star rating, while the Kepswin only has 11 reviews at 3.7 stars β so the YELOMIN is the safer bet if reliability matters most.
Can I take either of these on a plane?
Yes, both are safe for air travel. The Kepswin has a total power of 74Wh and is UL, CE, FCC, RoHS, and UN38.3 certified β all the stamps you need for carry-on luggage. The YELOMIN also states its 74Wh total power meets air travel regulations. Just remember that any power bank over 100Wh needs airline approval, so these are well under that limit.
My Final Verdict
The Kepswin Solar Charger 20 is my overall winner for most campers and hikers β its 4 built-in cables and compact 5.9-inch size make it the most convenient solar power bank I’ve tested this year. The YELOMIN is the better choice only if you absolutely need its massive 38800mAh capacity for extended off-grid trips, but the Kepswin’s grab-and-go design wins for everyday outdoor use.
If you’re still on the fence, ask yourself this: do you want to carry extra cables or not? The Kepswin has them built in, charges up to 6 devices at once, and slips into a pocket. For most people, that’s the smarter buy.
