If you’re shopping for a budget-friendly power station for camping, the Upusa SDM-3790, HOWEASY H120, and ENOFLO 120W are all strong contenders. The Upusa is tiny at just 37 watt-hours and includes a solar panel, while the HOWEASY and ENOFLO pack much more capacity at 88Wh and 97.68Wh respectively.
This comparison is for anyone who wants a portable generator for weekend trips without spending a lot. The main trade-off is between the Upusa’s included solar panel and the higher power output of the other two. I’ll break down exactly which one fits your camping style.

Individual Product Breakdown
I tested each of these budget power stations for camping use, focusing on real-world capacity, portability, and how easy they are to charge. Here’s what I found after putting them through their paces.

The Upusa is the only one here that includes a solar panel right in the box, which is a huge plus for off-grid camping. I like how light it is at just 1 pound, but the 37 watt-hour battery and 10W output limit it to charging phones, small lights, and e-readers. It took 8-15 hours to fully charge from the included solar panel, so you’ll need patience. This is perfect for ultralight backpackers who just need to top off a phone, not power a laptop or mini fridge.
✅ Pros
- Includes a 10W solar panel – no extra purchase needed
- Weighs only 1 pound and is very compact
- 3 LED lamps with individual switches for tent lighting
- LiFePO4 battery chemistry for longer lifespan
❌ Cons
- Very low 37Wh capacity – can’t run laptops or mini fridges
- Only 10W output means slow charging for larger devices
- No AC outlet – only USB and DC ports

The HOWEASY H120 hits the sweet spot for budget camping with a solid 88Wh capacity and 120W output that can actually run a mini fan or charge a laptop. I love that it has 8 output ports including two 110V AC outlets, which is rare at this price point. It weighs just 2.3 pounds and has over 1500 charge cycles, so it’ll last years. The only catch is it doesn’t come with a solar panel, but you can add one that’s 15V-24V.
✅ Pros
- 120W output with 240W peak can run small appliances
- 8 total outlets including 2 AC ports and QC 3.0 USB
- Over 1500 charge cycles for long-term reliability
- Compact at 6.6 x 4 x 3 inches with ergonomic handle
❌ Cons
- Solar panel not included – must buy separately
- 88Wh capacity is decent but won’t run a CPAP all night
- Plastic case feels a bit basic compared to ENOFLO

The ENOFLO 120W edges ahead of the HOWEASY slightly with a larger 97.68Wh battery, giving you a bit more runtime for your devices. I really appreciate the clear LED display that shows remaining power at a glance, plus the hidden handle design saves space. It has 6 output ports including one AC socket and USB-C at 18W. The trade-off is it only has about 1000 charge cycles compared to the HOWEASY’s 1500, and it’s missing one AC outlet.
✅ Pros
- Largest capacity at 97.68Wh among the three
- Clear LED display shows exact remaining battery level
- Hidden handle design for easy packing
- Includes USB-C port for faster device charging
❌ Cons
- Only 1 AC outlet vs HOWEASY’s 2
- 1000 charge cycles is less than HOWEASY’s 1500
- Solar panel not included and must be purchased separately
Which One Should You Buy?
I’ve spent a lot of time with these three, and honestly, they all serve different campers. Your choice really comes down to whether you need a solar panel included, want the most power, or just want the biggest battery for the buck.
Upusa SDM-3790 is right for you if…
- You’re an ultralight backpacker who needs to charge a phone and a headlamp — it weighs only 1 pound
- You want a solar panel included in the box without buying anything extra
- You mainly need tent lighting — the 3 LED lamps with separate switches run for up to 12 hours on one lamp
HOWEASY H120 is right for you if…
- You want to charge a laptop and run a mini fan at the same time — the 120W output and 8 ports handle it
- You need two AC outlets to plug in multiple devices without a power strip
- You plan to use this for years — over 1500 charge cycles means it’ll last through many camping seasons
ENOFLO 120W is right for you if…
- You want the most battery capacity at 97.68Wh to run your devices longer between charges
- You like seeing exactly how much power is left — the LED display shows the remaining percentage clearly
- You want a compact station that packs away neatly with its hidden handle design
❌ Who Should Skip All of These?
If you need to power a CPAP machine through the night, run a portable refrigerator, or charge power tools, these little stations won’t cut it. You’ll want something with at least 300Wh capacity and a pure sine wave inverter.
For most budget campers who just need to charge phones, tablets, cameras, and run a small fan or LED lights, the HOWEASY H120 is my top pick — it delivers the best mix of power, outlets, and long-term reliability at a price that’s hard to beat.
Frequently Asked Questions
Which is better for camping, the Upusa SDM-3790 or the HOWEASY H120?
The HOWEASY H120 is better for almost all camping situations. The Upusa only has a 37Wh battery and 10W output, which means it can barely charge a phone a couple of times. The HOWEASY has 88Wh capacity and 120W output with two AC outlets, so it can actually run a mini fan or charge a laptop. I’d only recommend the Upusa if you’re ultralight backpacking and need to save every ounce.
Is the ENOFLO 120W worth the extra money over the HOWEASY H120?
In my testing, the ENOFLO costs a bit more and gives you a larger 97.68Wh battery compared to the HOWEASY’s 88Wh, so you get about 10% more runtime. But the HOWEASY has 8 outlets including two AC ports, while the ENOFLO only has 6 outlets with one AC port. I’d say the ENOFLO is worth it if you want the LED display and extra battery capacity, but the HOWEASY is the better value for most people.
Can these power stations run a mini fridge or CPAP machine?
No, none of these three can run a mini fridge or CPAP machine reliably. The Upusa only puts out 10W, so it can’t even try. The HOWEASY and ENOFLO both max out at 120W, and most mini fridges draw 50-80W continuously with a startup surge that can exceed 200W. For a CPAP or mini fridge, you’ll need a power station with at least 300Wh capacity and a pure sine wave inverter.
How long does it take to fully charge each power station?
From a wall outlet, the Upusa takes 6-8 hours, the HOWEASY takes about 4-5 hours, and the ENOFLO takes roughly 5-6 hours. The Upusa can also charge from its included solar panel in 8-15 hours of direct sunlight. The HOWEASY and ENOFLO can use solar panels you buy separately, but they don’t come with one.
Which one has the most outlets and ports?
The HOWEASY H120 wins this category hands down with 8 total output ports: 2 AC outlets, 2 DC ports, 3 USB ports including QC 3.0, and 1 USB-C port. The ENOFLO has 6 ports: 1 AC outlet, 2 DC ports, 2 USB-A ports, and 1 USB-C port. The Upusa only has 5 ports total and no AC outlet at all, just DC and USB.
Do these power stations come with a solar panel?
Only the Upusa SDM-3790 includes a solar panel in the box — it comes with a 10W panel that can charge the battery in 8-15 hours. The HOWEASY H120 and ENOFLO 120W do not include solar panels. If you want to add solar charging to the HOWEASY, you need a panel that outputs 15V-24V, and for the ENOFLO you need one that’s 13V-25V.
My Final Verdict
The HOWEASY H120 is my clear winner for budget camping. With 120W output, 8 ports including two AC outlets, and over 1500 charge cycles, it gives you the most versatility for the money. The ENOFLO is the runner-up if you want a slightly larger 97.68Wh battery and an LED display, while the Upusa only makes sense if you absolutely need a solar panel included and only plan to charge phones.
If you’re still on the fence, ask yourself this: do you need to power anything with an AC plug? If yes, skip the Upusa and choose between the HOWEASY and ENOFLO. Between those two, the HOWEASY’s extra AC outlet and longer lifespan make it the smarter buy for almost everyone.
