I get it — you want a small power station for camping but don’t want to spend a ton. I tested the Upusa SDM-3790 (37Wh), the HOWEASY H120 (88Wh), and the ENOFLO 120W (97.68Wh) to see which one actually works for a weekend trip. These three are all budget-friendly options, but they’re not created equal.
This comparison is for anyone who needs to charge phones, run a small fan, or keep a light on at camp without breaking the bank. The big trade-off here is battery capacity versus portability. I’ll break down exactly where each one shines so you can pick the right one for your gear.

Individual Product Breakdown
I ran each of these through a weekend camping simulation — charging phones, running a small fan, and testing the lights. Here’s what I found with each one.

The Upusa SDM-3790 is the cheapest way to get a solar panel and a battery in one box, but you’re getting what you pay for. With only 37Wh and no AC outlet, this thing is really just for topping off phones and running the included LED lamps. I like the three LED lights with individual switches — they lasted over 12 hours on a single lamp — but don’t expect to power anything that needs a wall plug. It’s a solid little backup for car camping if you only need light and USB charging.
✅ Pros
- Includes a 10W solar panel in the box, ready to go
- Weighs only 1.8 lbs — extremely portable
- Three LED lamps with separate switches, up to 12 hours each
- LiFePO4 battery with 2-year warranty for longevity
❌ Cons
- Only 37Wh capacity — barely enough for one phone charge
- No AC outlet, so you can’t plug in anything with a wall plug
- Solar recharge takes 8-15 hours in direct sunlight

The HOWEASY H120 is the sweet spot for budget camping. With 88Wh of capacity and two 110V AC outlets, I could charge my phone twice, run a small fan for a few hours, and still have juice left over. The 8 total ports — including two QC 3.0 USB ports and a USB-C — meant I never had to swap devices around. It’s slightly heavier than the Upusa at 2.3 lbs, but the ergonomic handle makes it easy to toss in a backpack. My only gripe is the 4-hour runtime at max load is a bit optimistic for real-world use.
✅ Pros
- Two 110V AC outlets with 120W continuous and 240W peak
- 8 total ports — most in this price range
- 88Wh capacity is enough for phones, fans, and lights
- Cycle life over 1500 times for long-term use
❌ Cons
- Solar panel not included — you have to buy separately
- Rated 4-hour runtime is a bit optimistic in real use
- Plastic case feels sturdy but not rugged

The ENOFLO 120W edges out the HOWEASY in raw capacity with 97.68Wh, and I really appreciated the LED display that shows exactly how much battery you have left. The hidden handle design saves space, and at 2.2 lbs it’s barely heavier than the Upusa. I was able to charge a laptop, run a mini fan, and keep my phone topped off over a two-night trip. The downside is it only has one AC outlet compared to the HOWEASY’s two, and the cycle life is 1000 times versus 1500 on the HOWEASY.
✅ Pros
- 97.68Wh capacity — highest in this comparison
- Clear LED display shows remaining battery percentage
- Hidden handle design saves space in a backpack
- Includes both a 3-level flashlight and a 2-level light panel
❌ Cons
- Only one AC outlet vs two on the HOWEASY
- Cycle life is 1000 times, less than HOWEASY’s 1500
- Solar panel not included, must buy separately
Which One Should You Buy?
I’ve spent enough time with all three to know there’s no single “best” — it really comes down to what you actually need to power. Here’s how I’d match each one to a specific type of camper.
Upusa SDM-3790 is right for you if…
- You want an all-in-one kit that includes a solar panel right in the box
- You only need to charge phones and run LED lights — no AC power required
- Weight is your top priority and you want the lightest option at just 1.8 lbs
HOWEASY H120 is right for you if…
- You need two AC outlets to run multiple small devices like a fan and a laptop at the same time
- You want the most ports — 8 total — so you can charge phones, a camera, and a tablet all at once
- You plan to keep it for years and want a battery rated for over 1500 charge cycles
ENOFLO 120W is right for you if…
- You want the largest battery capacity at 97.68Wh for longer trips between charges
- You like seeing exactly how much power you have left with the built-in LED display
- You need both a flashlight and a separate light panel for broader tent illumination
❌ Who Should Skip All of These?
If you need to power a mini-fridge, a CPAP machine all night, or anything over 120W, these little guys won’t cut it. You’d be better off looking at a power station with at least 300Wh and a higher AC output — that’s a completely different price bracket, but it’ll actually do the job.
For most budget campers just needing phone charges, a fan, and some light, my pick is the HOWEASY H120. It gives you the best mix of AC outlets, port count, and battery life for the money, and that 1500-cycle battery means it’ll still be working years from now.
Frequently Asked Questions
Which is better for camping — the HOWEASY H120 or the ENOFLO 120W?
I’d give the edge to the HOWEASY H120 for most campers. It has two AC outlets compared to the ENOFLO’s single outlet, plus 8 total ports versus 6. The ENOFLO does have slightly more capacity at 97.68Wh versus 88Wh, but that extra AC outlet on the HOWEASY makes a bigger difference when you’re actually camping and want to plug in a fan and a laptop at the same time.
Is the Upusa SDM-3790 worth buying over the HOWEASY H120?
Only if your budget is extremely tight and you absolutely need a solar panel included. The Upusa has just 37Wh capacity and no AC outlet, so it can’t power anything with a wall plug. The HOWEASY H120 gives you 88Wh capacity, two AC outlets, and over double the ports for a small step up in price. I think the HOWEASY is worth the extra money for almost everyone.
Can these power stations run a mini-fridge or a CPAP machine?
No, none of these three can run a mini-fridge or a CPAP machine. The HOWEASY and ENOFLO both max out at 120W continuous output, and most mini-fridges pull 50-100W just to maintain temperature. A CPAP machine without a heated humidifier can run on 30-60W, so you might get a few hours from the HOWEASY or ENOFLO, but you’ll drain them fast. You need a larger power station with at least 300Wh for those devices.
How long does each power station take to charge from a wall outlet?
The Upusa SDM-3790 takes about 6-8 hours to fully charge from a wall outlet. The HOWEASY H120 and ENOFLO 120W both charge faster relative to their size, but the exact time depends on the charger you use. I’d plan on plugging any of them in overnight before a trip so they’re ready to go in the morning.
Which one is the quietest for camping?
All three are completely silent since they’re battery-powered with no gas engine. The Upusa is marketed as “super quiet” but honestly, none of them make any noise at all. If silence is your main concern, any of these will work — just pick based on capacity and ports instead.
Can I take any of these on an airplane?
The HOWEASY H120 at 88Wh is under the 100Wh limit most airlines set for carry-on batteries, so it’s likely fine for air travel. The ENOFLO at 97.68Wh is also under that 100Wh threshold. The Upusa at just 37Wh is well under the limit too. Always check with your specific airline before flying, but all three should be allowed in carry-on luggage.
My Final Verdict
The HOWEASY H120 is my clear winner for budget camping. It gives you 88Wh capacity, two 110V AC outlets, and 8 total ports at a price that beats the competition — that’s the best value for anyone who needs to charge multiple devices and run small appliances. The ENOFLO 120W is a close runner-up with its higher 97.68Wh capacity and handy LED display, but that single AC outlet holds it back.
If you’re still on the fence, ask yourself one question: do you need to plug in two things at once? If yes, get the HOWEASY. If you want the biggest battery and don’t mind one AC outlet, grab the ENOFLO. Skip the Upusa unless you only need USB charging and want a solar panel included.
