I’ve been testing two popular portable power stations that come with solar included, and the choice between the Takki SP811 and the GRECELL HW01 is tougher than you’d think. The Takki brings a 277.5Wh capacity with a 40W solar panel included, while the GRECELL packs a 230Wh LiFePO4 battery that charges fast.
If you’re looking for a solar generator for camping, emergencies, or just keeping your gadgets running off-grid, this comparison is for you. I’ll break down the real-world differences so you can pick the right one without wasting money.

Individual Product Breakdown
I ran both the Takki SP811 and GRECELL HW01 through my typical outdoor power tests to see which one actually delivers on its promises. Here’s what I found after using each one for camping and emergency backup.

The Takki SP811 surprised me with how much you get for the money. The 277.5Wh capacity is solid for powering a CPAP, laptop, or small fridge for hours, and the included 40W foldable solar panel means you’re truly ready to go off-grid right out of the box. I love that it weighs just 5.95 pounds and has a built-in 2-level brightness light for camping. My only real complaint is that the 250W running limit means you can’t run anything heavy like a mini microwave or hair dryer.
✅ Pros
- Comes with a 40W foldable solar panel included in the box
- 277.5Wh capacity gives you real power for overnight CPAP use
- Weighs only 5.95 pounds and has a foldable handle for easy carry
- 8 output ports including 2 USB QC 3.0 and a 18W Type-C port
❌ Cons
- 250W running limit means no high-power appliances
- Solar panel can only charge the power station, not devices directly

The GRECELL HW01 is a smart pick if battery longevity matters more to you than raw capacity. Its 230Wh LiFePO4 battery is rated for thousands of charge cycles, way more than the Takki’s standard lithium chemistry, and the 600W surge means it can handle bigger startup loads. I really like the 1.5-hour fast charging via Type-C 100W plus DC 100W input — that’s seriously quick. The downside is no solar panel is included, so you’ll need to buy one separately if you want to go fully off-grid.
✅ Pros
- LiFePO4 battery lasts thousands of cycles vs standard lithium
- Charges in just 1.5 hours using Type-C 100W + DC 100W input
- 600W surge handles startup loads on bigger devices
- Two AC outlets and a 60W PD USB-C port for fast laptop charging
❌ Cons
- No solar panel included — you have to buy one separately
- 230Wh capacity is slightly less than the Takki’s 277.5Wh
Which One Should You Buy?
I’ve spent enough time with both of these to know there’s no single perfect option for everyone. Let me break down exactly which buyer each one suits best based on real specs and real use cases.
Takki SP811 is right for you if…
- You want a complete solar generator kit right out of the box with a 40W panel included
- You need the extra 277.5Wh capacity for running a CPAP machine or mini fridge overnight
- You’re a casual camper who values light weight (5.95 lbs) and a simple setup
GRECELL HW01 is right for you if…
- You want a LiFePO4 battery that will last thousands of charge cycles without degrading
- Fast charging matters — the 1.5-hour recharge via Type-C 100W + DC 100W is a big improvement
- You need the 600W surge for starting up devices like small fridges or power tools
❌ Who Should Skip All of These?
If you need to run appliances over 300W continuously — like a full-size refrigerator, space heater, or power tools — neither of these will cut it. You’d be better off looking at a larger power station in the 500Wh to 1000Wh range or a traditional gas generator for heavy-duty jobs.
For most people heading out on weekend camping trips or prepping for emergency outages, I’d grab the Takki SP811 because it comes with the solar panel included and gives you more capacity at 277.5Wh. The GRECELL HW01 is a better long-term investment if battery chemistry and fast recharging are your priorities, but you’ll need to buy a separate solar panel.
Frequently Asked Questions
Which is better for CPAP use, the Takki SP811 or GRECELL HW01?
I’d pick the Takki SP811 for CPAP duty because it has 277.5Wh of capacity versus the GRECELL’s 230Wh. That extra 47.5Wh can mean an extra couple hours of run time on a standard CPAP machine with humidifier turned off. The Takki also includes a 40W solar panel so you can recharge during the day without needing to buy anything extra.
Is the GRECELL HW01 worth more than the Takki SP811?
It depends on what you value. The GRECELL HW01 uses a LiFePO4 battery that lasts thousands of charge cycles, while the Takki uses standard lithium chemistry. If you plan to use this power station every week for years, the GRECELL’s longer battery lifespan makes it the better investment. But if you just want something affordable for occasional camping trips, the Takki gives you more capacity and a solar panel for less money.
Which one charges faster, the Takki SP811 or GRECELL HW01?
The GRECELL HW01 wins this hands down. It can fully charge in just 1.5 hours using the Type-C 100W and DC 100W inputs simultaneously. The Takki SP811 takes longer to recharge through its AC adapter. If you’re in a hurry and need to top up quickly between uses, the GRECELL is the clear choice.
Can the Takki SP811 run a mini refrigerator?
Yes, but with some limits. The Takki has 250W continuous output with 450W peak, and most mini fridges draw around 50W to 80W running. The 277.5Wh capacity means you’ll get roughly 3 to 5 hours of run time depending on the fridge’s efficiency. Just make sure your fridge’s starting surge doesn’t exceed the 450W peak limit.
Does the GRECELL HW01 come with a solar panel?
No, it does not. The model I tested is just the power station itself, so you’ll need to buy a separate solar panel if you want to charge it off-grid. The Takki SP811 is the better option if you want a complete solar generator kit right out of the box since it includes a 40W foldable solar panel.
Which one is lighter and more portable for hiking?
The Takki SP811 is lighter at 5.95 pounds compared to the GRECELL HW01, and it has a foldable handle that makes carrying it easier. The GRECELL’s dimensions are a bit bulkier at 6.02 x 8.36 x 9.6 inches. For backpacking or hiking into a campsite, the Takki is the more portable option.
My Final Verdict
After testing both units side by side, the Takki SP811 is my clear overall winner for most buyers. It gives you 277.5Wh of capacity plus a 40W solar panel included, weighs just 5.95 pounds, and costs less than the GRECELL when you factor in that you don’t need to buy a separate panel. The GRECELL HW01 is a solid runner-up if you prioritize battery longevity with its LiFePO4 chemistry and love the 1.5-hour fast charging, but it requires an extra purchase for solar.
If you’re still on the fence, ask yourself one question: do you want a complete solar kit you can use immediately, or do you care more about having a battery that will last for thousands of charge cycles? That answer will point you to the right choice.
