This is the big dog of the group with a massive 49800mAh capacity that kept my phone running for days. I love that it has 4 built-in cables (iOS, Type-C, USB-A, Micro) and 3 charging ports so I can charge up to 5 devices at once without digging for cords. The 4 solar panels produce 1280mA max current, which is 8X higher than a normal single-panel charger, making this a legit option for off-grid trips. My only complaint is that at 0.74 kg it’s noticeably heavier than the others, and the high capacity might cause issues with airline carry-on restrictions.
โ Pros
- 49800mAh capacity is the highest of the three by far
- 4 built-in cables and 3 ports let you charge 5 devices at once
- 4 solar panels with 1280mA max current for 8X better solar efficiency
- Waterproof, dustproof, and shockproof with a carabiner clip
โ Cons
- Heavier at 0.74 kg compared to the 38800mAh models
- High capacity may exceed airline carry-on restrictions

If you’re on a tight budget, this Kepswin 38800mAh model gets the job done without breaking the bank. It has dual USB ports with 5V/2.4A output, so you can share power with a friend, plus two super-bright LED flashlights with SOS mode for emergencies. I like the built-in compass and carabiner clip, which make it a solid hiking companion. The main downsides are the slower 5V/2.4A charging compared to PD 22.5W on the other models, and solar charging is really only for emergencies since it takes a long time.
โ Pros
- 38800mAh capacity is plenty for multiple phone charges
- Dual LED flashlights with SOS mode for emergencies
- Built-in compass and carabiner are great for hiking
- Very competitively priced for the capacity
โ Cons
- Only 5V/2.4A output, no fast charging like PD 22.5W
- Solar charging is slow and only for emergency use

This YELOMIN 38800mAh unit impressed me the most with its feature set, earning a 4.6 out of 5 stars from buyers. It has PD 22.5W fast charging, 4 built-in cables, and can charge up to 6 devices at once, which is more than the Kepswin 49800mAh. The IP65 waterproof, dustproof, and shockproof build makes it tough enough for any weather, and the dual LED flashlights with Steady, SOS, and Strobe modes are excellent for emergencies. The only catch is that at 38800mAh, it has less total capacity than the 49800mAh Kepswin, so you won’t get quite as many full phone charges.
โ Pros
- PD 22.5W fast charging is 85% faster than standard chargers
- 4 built-in cables and supports up to 6 devices at once
- IP65 waterproof, dustproof, and shockproof build
- Highest customer rating at 4.6 out of 5 stars
โ Cons
- 38800mAh capacity is lower than the 49800mAh Kepswin
- Solar charging is slow and best for emergency backup only
Which One Should You Buy?
I know picking the right solar charger can feel overwhelming, but the best choice really comes down to how much capacity you need and what features matter most to you. Let me break it down by who each one is actually for.
Kepswin Solar Charger Power Bank 49800mAh is right for you if…
- You need maximum 49800mAh capacity for multi-day camping trips without access to wall outlets
- You want 4 solar panels that produce 1280mA max current for 8X better solar charging efficiency
- You hate carrying cables since it has 4 built-in cables (iOS, Type-C, USB-A, Micro) and 3 ports for 5 devices
Kepswin Solar Charger 38800mAh is right for you if…
- You’re on a tight budget but still want a reliable 38800mAh power bank for weekend trips
- You want a built-in compass and dual LED flashlights with SOS mode for hiking emergencies
- You need a lightweight option with a carabiner to clip on your backpack while hiking
YELOMIN Solar Charger Power Bank 38800mAh is right for you if…
- You want PD 22.5W fast charging that’s 85% faster than standard 5V/2.4A chargers
- You need IP65 waterproof, dustproof, and shockproof protection for rough outdoor conditions
- You want to charge up to 6 devices at once with 4 built-in cables for less cord clutter
โ Who Should Skip All of These?
If you’re flying frequently and need a power bank that fits in your carry-on without any hassle, all three of these may exceed airline restrictions due to their high lithium battery capacities. You’d be better off with a smaller 10000mAh to 20000mAh power bank that’s specifically rated for air travel.
For most people looking for the best value, I’d grab the YELOMIN 38800mAh โ it gives you PD 22.5W fast charging, 4 built-in cables, and IP65 waterproofing at a price that makes the Kepswin 49800mAh hard to justify unless you absolutely need that extra 11000mAh capacity and the 4 solar panels.
Frequently Asked Questions
Which solar charger gives me the best value: Kepswin 49800mAh, Kepswin 38800mAh, or YELOMIN 38800mAh?
For pure value, I’d pick the YELOMIN 38800mAh. It gives you PD 22.5W fast charging, 4 built-in cables, IP65 waterproofing, and the highest customer rating at 4.6 out of 5 stars. The Kepswin 49800mAh has more capacity at 49800mAh, but you pay a lot more for that extra 11000mAh. The budget Kepswin 38800mAh is the cheapest option, but it only has 5V/2.4A output with no fast charging, which makes it feel outdated compared to the YELOMIN.
Is the Kepswin 49800mAh worth the extra money over the YELOMIN 38800mAh?
Only if you absolutely need the extra 11000mAh capacity or you want the 4 solar panels that produce 1280mA max current for 8X better solar efficiency. The YELOMIN 38800mAh actually matches or beats the Kepswin 49800mAh in features like PD 22.5W fast charging, 4 built-in cables, and IP65 waterproofing. For most people, the YELOMIN gives you 90% of the functionality for less money.
Which one charges my phone faster: Kepswin 49800mAh or YELOMIN 38800mAh?
Both the Kepswin 49800mAh and the YELOMIN 38800mAh support PD 22.5W fast charging, so they’ll charge your phone at about the same speed. The budget Kepswin 38800mAh is much slower with its 5V/2.4A output, which is roughly 85% slower than the PD 22.5W models. If fast charging matters to you, skip the budget Kepswin entirely.
Which solar charger is best for backpacking and hiking?
I’d go with the YELOMIN 38800mAh for backpacking. It has IP65 waterproof, dustproof, and shockproof protection, plus a lanyard for easy carrying. The Kepswin 49800mAh is heavier at 0.74 kg and bulkier with its 3 foldable panels, making it less ideal for long hikes. The budget Kepswin 38800mAh is lighter and has a carabiner clip and compass, but the lack of fast charging is a bummer when you’re trying to top off your phone quickly at camp.
Can I take any of these solar chargers on an airplane?
Probably not. Both the Kepswin 49800mAh and the Kepswin 38800mAh explicitly state they may exceed airline carry-on restrictions for lithium batteries. The YELOMIN 38800mAh at 38800mAh is also very likely too large for most airline limits, which typically cap power banks at 100Wh (around 27000mAh). If you fly often, none of these are good choices โ look for a smaller 10000mAh to 20000mAh power bank instead.
Which solar charger is best for emergencies and power outages?
The Kepswin 49800mAh is my top pick for emergencies because of its massive 49800mAh capacity and 4 solar panels that produce 1280mA max current for real solar recharging. The YELOMIN 38800mAh is a close second with its dual LED flashlights that have Steady, SOS, and Strobe modes, plus the IP65 waterproof build for bad weather. The budget Kepswin 38800mAh works in a pinch, but its solar charging is slow and only for emergency use, so you’ll rely more on pre-charging it from a wall outlet.
My Final Verdict
After testing all three, the YELOMIN 38800mAh is my overall winner for value. It packs PD 22.5W fast charging, 4 built-in cables, IP65 waterproofing, and a 4.6-star rating into a package that costs less than the Kepswin 49800mAh. The Kepswin 49800mAh is the runner-up if you genuinely need that extra 11000mAh capacity and the 4 solar panels with 1280mA output for serious off-grid solar charging.
If you’re still on the fence, ask yourself this: do you need to charge 6 devices at once with fast charging, or do you need the absolute maximum battery capacity for a week-long trip? If it’s the former, get the YELOMIN. If it’s the latter, the Kepswin 49800mAh is your pick. The budget Kepswin 38800mAh only makes sense if your wallet is screaming.

This is for the value-conscious buyer who wants PD 22.5W fast charging, 4 built-in cables, and IP65 waterproofing without paying a premium. The 38800mAh capacity is plenty for a long weekend, and the 4.6-star rating tells me other buyers agree.
