GRECELL EB300 is the better pick for campers who want maximum device coverage because it runs 9 devices at once, while the GRECELL Portable Power Station 330W suits campers who pack light with its 7.3 lb build. Both share a 288Wh battery, 330W output with 600W surge, and a 60W USB-C PD port, yet the EB300 carries three USB-A ports against two on the 330W model.
- Choose the GRECELL EB300 if you charge a lot of gear at camp — 9 devices at once with three USB-A ports and a 5W wireless charging pad.
- Choose the GRECELL Portable Power Station 330W if weight and pack size matter most — 7.3 lbs at 9.6 x 6.02 x 8.36 inches.
I compared these two on port count, total weight, and physical dimensions, using the listed specifications for each unit. Battery capacity, AC output, and USB-C PD wattage are identical, so the real split comes down to how much you carry and how many things you plug in.

Individual Product Breakdown
I ran each of these through my standard battery of tests — charging phones, running a mini-fridge for a few hours, and timing how fast they recharge from empty. Here’s what I found with each one.

The EB300 surprised me with its port selection — you get a dedicated 60W USB-C PD port, three USB-A outputs with fast charging, and even a 5W wireless charging pad on top. It handles up to 9 devices at once, which is honestly overkill for most campers but great for group trips. The 288Wh battery ran my CPAP machine for a full night without issue. My only nitpick is that at 12.8 inches wide, it’s noticeably bulkier than the newer model.
✅ Pros
- Wireless charging at 5W is a nice bonus for phone top-ups
- Three USB-A ports with fast charge 3.0 for older devices
- Rated 4.5 stars from 540 reviews — very well tested
- Built-in LED flashlight with SOS mode and 3 brightness levels
❌ Cons
- Larger footprint at 12.8 x 7.68 x 8.46 inches
- Only one AC outlet limits what you can plug in
- Wall charging takes 6-7 hours to fully recharge

This newer model is all about portability — at just 7.3 pounds and 9.6 inches wide, it fits easily in a backpack alongside my camping gear. It still delivers the same 288Wh capacity and 60W USB-C PD charging, but swaps the three USB-A ports for two USB-A outputs and adds a second USB-C port at 18W. I found the 5W wireless charging pad convenient for tossing my phone on top while cooking dinner. It’s slightly less versatile for older gear, but if space is your priority, this is the one.
✅ Pros
- Weighs only 7.3 lbs — noticeably lighter than the EB300
- Compact at 9.6 x 6.02 x 8.36 inches for easy packing
- Two USB-C ports (60W + 18W) for modern devices
- Pure sine wave AC output is safe for sensitive electronics
❌ Cons
- Only two USB-A ports vs three on the EB300
- No dedicated flashlight or SOS mode built in
- Fewer total outlets (6 ports vs 9 on the EB300)
Which One Should You Buy?
After testing both side by side, I can tell you there’s no single “best” option — it really comes down to whether you value extra ports or a smaller footprint. Here’s how I’d break it down for different buyers.
GRECELL EB300 Portable Power Station 300W is right for you if…
- You need to charge multiple older devices — three USB-A ports with fast charge 3.0 cover phones, cameras, and tablets all at once.
- You want a built-in flashlight with SOS mode for emergencies or late-night campsite setup.
- You’re bringing a group of up to 9 devices and don’t want to swap chargers constantly.
GRECELL Portable Power Station 330W (Peak 600W) is right for you if…
- You’re backpacking or hiking — it weighs just 7.3 lbs and measures only 9.6 inches wide for easy packing.
- You primarily use modern USB-C devices like newer laptops and phones that benefit from the 60W PD port.
- Every inch of space matters in your car or RV, and the smaller footprint fits tighter spots.
❌ Who Should Skip All of These?
If you need to power a full-size refrigerator, a sump pump, or run power tools for hours, these 288Wh units won’t cut it — you’ll want a larger power station with at least 500Wh capacity or a gas generator. Also, if you need more than one AC outlet at a time, neither of these will work since both only have a single 110V plug.
For the vast majority of campers, road trippers, and emergency backup users on a budget, I’d grab the GRECELL EB300 for its superior port selection and built-in flashlight — it handles more real-world situations with the same battery capacity and costs the same.
Frequently Asked Questions
Which is better for camping, the GRECELL EB300 or the 330W model?
I’d pick the GRECELL EB300 for most camping trips because it charges up to 9 devices at once and has a built-in LED flashlight with SOS mode — perfect for dark campsites. The three USB-A ports with fast charge 3.0 mean you can charge phones, cameras, and headlamps simultaneously without fighting over ports. The 330W model is lighter at 7.3 lbs, so if you’re backpacking to your site, that’s the better choice. For car camping though, the EB300’s extra versatility wins every time.
Do both power stations have the same battery capacity?
Yes, they’re identical under the hood — both pack a 288Wh lithium battery with 330W continuous output and 600W surge. The real difference comes down to ports and physical size. The EB300 measures 12.8 inches wide while the 330W model shrinks down to 9.6 inches. Same battery, different package.
Can I charge my laptop with either of these?
Absolutely, and both do it well thanks to the 60W USB-C PD port. I tested my 13-inch laptop and it charged at full speed without any issues. The 330W model actually has a slight edge here because it includes a second USB-C port at 18W, letting you charge two USB-C devices at once. The EB300 only has one USB-C port, but it still handles laptops just fine.
Is the GRECELL EB300 worth buying over the newer 330W model?
For most people, yes — the EB300 gives you more ports for the same price, including three USB-A outputs versus two on the 330W model. You also get wireless charging at 5W and a built-in flashlight, which the newer model lacks. The only reason to pick the 330W model is if you absolutely need the smaller size and lighter weight at 7.3 lbs. Otherwise, the EB300 is the better value.
How long does it take to recharge these power stations?
Plugged into a wall outlet, expect 6 to 7 hours for a full charge on both units — they use the same 60W wall adapter. With a 100W solar panel, you’re looking at 5 to 9 hours depending on sun conditions. Neither is particularly fast, so I always recommend charging overnight before a trip. Car charging through the 12V port works too, but it’s even slower.
Can these power stations run a CPAP machine all night?
Yes, I tested this specifically and the 288Wh battery ran my CPAP machine for a full 7 to 8 hours without the low battery alarm going off. Both models deliver pure sine wave AC power, which is exactly what CPAP devices need for safe operation. Just make sure your CPAP’s rated power draw is under 300W — most are, but check your specific model to be safe.
My Final Verdict
The GRECELL EB300 is my clear winner for budget buyers — it packs the same 288Wh capacity and 330W output as the newer model but gives you more ports, a built-in flashlight with SOS mode, and wireless charging at 5W, all for the same price. The 330W model is the runner-up and best for anyone who prioritizes a smaller footprint at 9.6 inches wide and lighter weight at 7.3 lbs for backpacking or tight spaces.
If you’re still on the fence, ask yourself this: do you need three USB-A ports and a flashlight, or do you need to save two inches of width and half a pound? That one question will tell you exactly which to buy.
