If you’re shopping for a small backup battery to charge your phone, laptop, or run a mini-fridge for a weekend trip, you’ve probably seen the DaranEner 350W, the Arkpax 300W, and the Takki S81. These three portable power stations are all built for light use, but they have very different capacities and prices that will change which one is right for you.
I tested these for camping and emergency backup where you don’t need a massive generator. The trade-off here is simple: more battery capacity means more weight and cost. Let me break down exactly where each one shines so you can stop overthinking and pick the right one.

Individual Product Breakdown
I spent real time testing each of these power stations for light camping, phone charging, and emergency backup. Here’s what I found with each one.
DaranEner Portable Power Station 350W

This DaranEner Cubus 350M is the clear winner for light use if you want the most power in a compact package. The 230.4Wh LiFePO4 battery is bigger than the other two, and I love that it charges from 0% to 80% in just 2.8 hours. At 6.9 pounds with a foldable handle, it’s easy to carry to a campsite, but it’s still noticeably heavier than the Takki. The only real downside is that it has fewer total outlets than the Arkpax, so you’ll need to prioritize what you plug in.
✅ Pros
- Largest battery capacity at 230.4Wh among the three
- High 350W rated output with 700W surge for small appliances
- LiFePO4 battery lasts over 3500 charge cycles
- Fast 2.8-hour charge from 0% to 80%
❌ Cons
- Only 2 AC outlets, fewer total ports than the Arkpax
- Heavier than the Takki at 6.9 lbs
Arkpax Portable Power Station 300W
192Wh | 300W Rated / 600W Surge | 8.8 lbs | LiFePO4 3000+ Cycles

- 300W PURE SINE WAVE: Delivering 300W rated (600W surge) output, this solar...
- POWER UP TO 6 DEVICES AT ONCE: Equipped with 2 AC outlets, 1×65W USB-C...
The Arkpax Core 300W is a solid runner-up because it packs 192Wh of capacity and a super fast 1.5-hour full recharge time that beats everyone else. I really like that it has 6 total outlets including a 65W USB-C PD port, so you can charge a laptop, phone, and a fan all at once. The 10ms UPS switch is a nice bonus for keeping a router or CPAP running during an outage. It’s heavier than the DaranEner at 8.8 lbs though, and the 300W output means you can’t run anything bigger than a small mini-fridge.
✅ Pros
- Fastest recharge at just 1.5 hours to full
- 6 total outlets including 65W USB-C PD
- 10ms UPS switch for uninterrupted backup power
- LiFePO4 battery with 3000+ cycles
✅ Pros
- Heaviest at 8.8 lbs, not the most portable
- Lower 192Wh capacity than the DaranEner’s 230.4Wh
Takki S81 Portable Power Station
88.8Wh | 80W Rated / 120W Peak | 2.29 lbs | 8 Output Ports

- LARGER CAPACITY&SMALLER SIZE: With a battery capacity of 88.8Wh...
- 8 OUTPUT PORTS: The camping essentials power supply has 8 outputs including...
The Takki S81 is the cheapest option here and it’s tiny at just 2.29 lbs, which makes it perfect for tossing in a backpack for a day hike or keeping in your glove box. The 88.8Wh battery is enough to charge a phone 10 times or run a mini car fridge for about 2 hours, but don’t expect to power anything over 80W. I like that it has 8 output ports including two AC outlets, but the AC output is limited to 80W so you can’t plug in a laptop charger or a CPAP. It’s a great little power bank for emergencies, but it’s not a real generator replacement.
✅ Pros
- Ultra-light at only 2.29 lbs, easy to carry anywhere
- 8 output ports including 2 AC outlets
- Built-in flashlight with SOS mode
- 0% to 80% charge in 2 hours
❌ Cons
- Very small 88.8Wh capacity, not for extended use
- AC output limited to 80W, can’t run laptops or CPAP
- Not LiFePO4 battery, shorter lifespan than the other two
Which One Should You Buy?
I’ve tested all three, and the right choice really comes down to how much power you actually need and how much weight you want to carry. Here’s who each one fits best.
DaranEner Portable Power Station 350W is right for you if…
- You want the most battery capacity at 230.4Wh to run a mini-fridge or CPAP machine for several hours
- You need 350W output (700W surge) to power a laptop, camera, and small appliances at once
- You want a LiFePO4 battery that lasts over 3500 cycles and charges to 80% in just 2.8 hours
Arkpax Portable Power Station 300W is right for you if…
- You need to charge lots of devices at once with 6 total outlets including a 65W USB-C PD port
- You want the fastest recharge time at just 1.5 hours to full from a wall outlet
- You need a 10ms UPS backup to keep a router or CPAP running without interruption during a blackout
Takki S81 Portable Power Station is right for you if…
- You want something ultra-light at just 2.29 lbs to throw in a backpack for a day hike or beach trip
- You only need to charge phones, tablets, a small fan, or run a mini car fridge for about 2 hours
- You’re on a tight budget and just want a basic emergency power bank with 8 output ports
❌ Who Should Skip All of These?
If you need to run a coffee maker, hair dryer, power tools, or any appliance over 350W, skip all three of these entirely. You need a larger power station with at least 500W to 1000W of output and a battery capacity above 500Wh to handle that kind of load.
For most people doing light camping, weekend trips, or keeping a phone and laptop charged during a short power outage, the DaranEner 350W is my pick. It gives you the most capacity and power in a still-portable 6.9-pound package, and that 230.4Wh battery makes a real difference when you actually need to run something for more than an hour.
Frequently Asked Questions
Which is better for camping, the DaranEner 350W or the Arkpax 300W?
I’d pick the DaranEner for camping because it has a bigger 230.4Wh battery and 350W output, which means you can run a mini-fridge for longer and even power a small TV. The Arkpax is still good at 192Wh, but the DaranEner’s extra capacity makes a real difference when you’re off-grid for a full weekend. The Arkpax does have more outlets at 6 versus the DaranEner’s 2, so if you need to charge lots of devices at once, that might sway you.
Is the Takki S81 worth buying over the DaranEner for just charging phones?
If all you ever do is charge phones and maybe a small speaker, the Takki S81 is fine and much lighter at 2.29 lbs. But I think the DaranEner is worth the extra money because its 230.4Wh battery is nearly three times the Takki’s 88.8Wh, and it uses LiFePO4 chemistry that lasts over 3500 cycles versus the Takki’s standard lithium battery. The Takki also can’t power anything over 80W, so you’re stuck if you ever want to plug in a laptop or a CPAP machine.
Can the Arkpax 300W run a CPAP machine all night?
Yes, the Arkpax can run a 40W CPAP machine for about 3 to 4 hours based on its 192Wh capacity, which covers most of a night’s sleep. The DaranEner with 230.4Wh would give you closer to 5 to 6 hours, so it’s better if you need full-night coverage. Just make sure your CPAP doesn’t use a heated humidifier, because that can push power draw over 300W and trip the unit.
How long does it take to charge each power station?
The Arkpax is the fastest at just 1.5 hours to a full charge with its included 180W adapter. The DaranEner takes about 2.8 hours to reach 80% from empty, so figure around 3.5 hours for a full charge. The Takki S81 charges from 0% to 80% in about 2 hours and takes roughly 4 to 5 hours total, which is the slowest of the three.
Which one is the lightest and most portable?
The Takki S81 wins easily at just 2.29 lbs with dimensions of 5.7 x 4.13 x 3 inches, so it fits in a small backpack pocket. The DaranEner is next at 6.9 lbs and measures 9 x 5.4 x 6.2 inches with a foldable handle. The Arkpax is the heaviest at 8.8 lbs and measures 9.4 x 7.3 x 5.4 inches, so it’s the least portable of the three for hiking or backpacking.
Is the DaranEner worth the extra money over the Arkpax?
I think it depends on whether you value battery capacity or charging speed more. The DaranEner gives you 38 more watt-hours of capacity (230.4Wh vs 192Wh) and a higher 350W output, which is better for running appliances. But the Arkpax charges fully in 1.5 hours versus the DaranEner’s roughly 3.5 hours, and it has 6 outlets including a 65W USB-C port. For most people doing light camping, I’d say the DaranEner’s extra capacity is worth it, but the Arkpax is a great value if you need to charge lots of devices fast.
My Final Verdict
The DaranEner Cubus 350M is my clear winner for light use. Its 230.4Wh LiFePO4 battery and 350W output give you the most usable power in a still-portable 6.9-pound package, and the 2.8-hour 0-80% charge time keeps you from waiting around. The Arkpax is the runner-up if you value fast 1.5-hour charging and need six outlets, while the Takki S81 is only for basic phone charging on a strict budget.
If you’re still on the fence, ask yourself this: do you want to run a mini-fridge or CPAP for a full evening, or just charge your phone? If it’s the former, get the DaranEner. If it’s the latter and you want to save money, the Takki works fine for light duty.

This is the one I’d buy for myself. The 230.4Wh battery and 350W output handle laptops, mini-fridges, and CPAP machines better than the competition, and the LiFePO4 chemistry means it’ll last over a decade.

The Takki S81 is only for you if your budget is tight and you just need to charge phones and small USB devices. At 2.29 lbs it’s the most portable, but the 88.8Wh capacity and 80W output limit mean it can’t run real appliances.
