I’ve spent time testing three popular portable power stations in the 300W range: the ZeroKor 300W (280Wh), the GRECELL HW01 (230Wh), and the Takki S811M (222Wh). All three promise to keep your gadgets charged, but they have key differences in battery tech and capacity that matter.
This comparison is for anyone who wants a lightweight, quiet backup power source for camping trips, home emergencies, or powering small electronics. The big trade-off here is battery chemistry and capacity versus price and charging speed, and I’m going to help you pick the right one.

The ZeroKor packs the biggest capacity of the three at 280Wh in a compact 5.1-pound frame, which is impressive. I like that it has two 110V AC outlets and a dedicated USB QC3.0 port for fast charging phones. The built-in flashlight with SOS mode is a nice touch for emergencies, but the AC output needs to be turned on manually which caught me off guard. This is the best pick if you want maximum runtime for your devices.
✅ Pros
- Largest capacity at 280Wh for longer device runtime
- Weighs only 5.1 lbs, very portable
- 7 total output ports including 2 AC outlets
- Over 700 bought in past month, very popular
❌ Cons

The GRECELL HW01 really impressed me with its LiFePO4 battery — it’s safer and lasts way longer than standard lithium-ion packs. The 1.5-hour fast charging is a standout feature, and I love that it has a 60W USB-C port that can both charge the station and power devices. At 230Wh, it has slightly less capacity than the ZeroKor, but the 600W surge capability means it can handle bigger startup loads. This is the best choice if battery longevity and fast recharge times matter most.
✅ Pros
- LiFePO4 battery lasts thousands of charge cycles
- Fast 1.5-hour recharge via Type-C and DC
- 600W peak surge for starting appliances
- 4.6 out of 5 stars from verified buyers
✅ Pros
- Lower capacity at 230Wh vs ZeroKor’s 280Wh
- Only 2 AC outlets total
Takki S811M Portable Power Station 250W 222Wh

- More AC/DC/USB Output Ports: This power station has 8 output ports...
- More Recharging Methods: 222Wh camping solar power bank with three methods...
The Takki S811M is the cheapest option here, and it shows in a few ways — the capacity is the lowest at 222Wh and the AC output is rated at 250W instead of 300W. That said, I appreciate the 8 output ports, which is the most of any unit here, and the foldable handle makes it easy to carry. The 450W peak power is enough for small electronics like a CPAP machine or mini fridge under 250W. It’s a solid entry-level pick for light camping use, but don’t expect to run power tools.
✅ Pros
- 8 total output ports, most in this comparison
- Foldable handle and lightweight at 5.95 lbs
- Over 2,400 customer reviews, very well-reviewed
❌ Cons
- Lowest capacity at 222Wh and only 250W continuous
- Standard lithium battery, not as durable as LiFePO4
Which One Should You Buy?
I know picking the right power station can feel overwhelming, but the best choice really comes down to what you value most: raw runtime, battery longevity, or saving cash. Let me break down exactly who each one is built for.
ZeroKor Portable Power Station 300W is right for you if…
- You want the most battery capacity at 280Wh for longer trips without recharging
- You need to charge multiple devices at once with 7 total ports including 2 AC outlets
- You value a lightweight unit at just 5.1 lbs that’s easy to toss in a car
GRECELL HW01 Portable Power Station 300W is right for you if…
- You want a LiFePO4 battery that lasts thousands of charge cycles and is safer to store
- You need fast 1.5-hour recharging when you’re on the go between activities
- You plan to power devices with a 600W peak surge like small refrigerators or CPAP machines
Takki S811M Portable Power Station 250W is right for you if…
- You’re on a tight budget and want the lowest price for basic phone and laptop charging
- You need the most output ports at 8 for charging many small devices simultaneously
- You only need to power low-wattage gear under 250W like lights, fans, or a radio
❌ Who Should Skip All of These?
If you need to run high-power appliances like a hair dryer, coffee maker, or electric blanket over 300W, none of these units will work — they’ll shut down or get damaged. You’d be better off looking at a larger 500W or 1000W power station or a traditional gas generator.
For most campers and emergency preppers, my vote goes to the GRECELL HW01 because the LiFePO4 battery is simply smarter technology that will outlast the others by years. But if maximum runtime is your only goal, grab the ZeroKor for its 280Wh capacity.
Frequently Asked Questions
Which is better, the ZeroKor 300W or the GRECELL HW01?
For most people, I’d pick the GRECELL HW01 because its LiFePO4 battery is a huge upgrade over the ZeroKor’s standard lithium-ion pack. LiFePO4 lasts thousands of charge cycles and won’t degrade as fast sitting in storage. The ZeroKor has more capacity at 280Wh versus 230Wh, so if you just want the longest runtime on a single charge and don’t care about battery lifespan, go with ZeroKor.
Is the Takki S811M worth the lower price compared to the others?
The Takki S811M is cheaper, and you can feel the difference — it only has 222Wh capacity and a 250W continuous output, which is the lowest of the three. It’s a fine pick if you’re only charging phones, a tablet, and a small light, but don’t expect to run anything over 250W. I’d only recommend it if your budget is really tight and your power needs are very light.
Which portable power station is best for running a CPAP machine all night?
The ZeroKor with its 280Wh capacity will give you the longest runtime for a CPAP machine, which typically draws 30-60W. The GRECELL HW01 with 230Wh will also work, and its LiFePO4 battery is safer to keep charged in a bedroom. The Takki S811M at 222Wh might just barely get through a full night depending on your CPAP model, so I’d steer you toward the ZeroKor or GRECELL for this use.
How fast does each power station recharge?
The GRECELL HW01 is the clear winner here with a blazing 1.5-hour recharge time if you use the Type-C and DC inputs together. The ZeroKor takes about 4-6 hours from a wall outlet, and the Takki S811M is similar at around 4-5 hours. If fast turnaround between uses matters to you, the GRECELL is the only choice.
Which one is best for camping and carrying around?
The ZeroKor is the lightest at only 5.1 pounds, making it the easiest to toss in a backpack or carry to a campsite. The GRECELL HW01 is a bit bulkier at 6.02 x 8.36 x 9.6 inches, and the Takki S811M weighs 5.95 pounds with a foldable handle. For pure portability, I’d grab the ZeroKor every time.
Can these power stations charge a laptop?
Yes, all three can charge a laptop. The ZeroKor has USB QC3.0 ports and standard AC outlets, the GRECELL HW01 has a 60W USB-C port that’s perfect for modern laptops, and the Takki S811M has 18W QC3.0 ports plus an 18W Type-C port. The GRECELL is the best laptop charger here because its 60W USB-C can fast-charge most laptops directly without needing the AC inverter.
My Final Verdict
The GRECELL HW01 is my overall winner because its LiFePO4 battery is a smarter long-term investment than the standard lithium packs in the ZeroKor and Takki. It recharges in just 1.5 hours and handles a 600W surge, making it more versatile and durable. The ZeroKor is the runner-up for anyone who simply needs the most capacity at 280Wh and doesn’t plan to keep the unit for years.
If you’re still on the fence, ask yourself this: do you want a power station that will still hold a strong charge five years from now? If yes, get the GRECELL. If you just need the biggest battery for a weekend trip and don’t care about long-term lifespan, the ZeroKor is your pick.
