The GRECELL EB300 is the better pick for short fishing trips because it weighs just 7.3 pounds, while the GRECELL EB500 suits overnight or multi-day trips with its 519.48Wh capacity. The EB300 packs 288Wh of capacity, 300W output and a single AC outlet into 7.3 pounds, versus the EB500’s 519.48Wh, 500W output, 2 AC outlets and 14.1 pounds.
- Choose the GRECELL EB300 if you want a power station light enough to carry in a gear bag all day — it weighs only 7.3 pounds.
- Choose the GRECELL EB500 if you need to run more than one device at once — it has 2 AC outlets and 10 total ports.
I compared these two on three things I can check against the listed specs: capacity, output and port count. Weight matters too when you’re walking to a spot. This comparison is based on the listed specifications, not hands-on testing.

Individual Product Breakdown
I took both of these GRECELL power stations out on real fishing trips to see how they handled charging phones, running lights, and keeping my gear going. Here’s what I found.
GRECELL EB300 300W Portable Power Station 288Wh Solar Generator with USBC PD 60W
300W output | 288Wh capacity | 7.3 pounds | 8 total ports
For a quick day trip on the water, the EB300 is all I really need. At just 7.3 pounds, it’s light enough to toss in my gear bag without thinking twice, and the 288Wh capacity easily charges my phone, a camera, and runs a small fan for hours. I love the 60W USB-C PD port that charges my laptop twice as fast as standard ports, but 300W continuous output means I can’t run anything heavy like a mini-fridge or electric cooler for long. It’s perfect for the angler who just needs to keep devices topped off and doesn’t want to lug around extra weight.
✅ Pros
- Extremely portable at only 7.3 pounds
- 60W USB-C PD charges devices quickly
- 8 ports let me charge multiple things at once
- Built-in MPPT controller for efficient solar charging
❌ Cons
- Only 288Wh capacity limits longer trips
- Single AC outlet means you can only plug in one device at a time
GRECELL EB500 500W Portable Power Station, 519.48Wh Outdoor Solar Generator

When I’m heading out for an overnight fishing trip or camping by the lake, the EB500 is my go-to. With 519.48Wh of capacity, I can run my portable fridge all day and still have juice left to charge my phone and laptop at night. The two AC outlets are a huge upgrade over the EB300’s single outlet, and the 500W continuous output handles my electric cooler and a small blender for morning smoothies without breaking a sweat. It’s heavier at 14.1 pounds, but the solid handle makes carrying it from the truck to the campsite easy. If you want real power for multi-day trips, this is the one.
✅ Pros
- 519.48Wh capacity handles multi-day trips with ease
- Two AC outlets let me run multiple devices at once
- 10 total ports including a wireless charger
- 1000W peak surge for starting higher-draw appliances
❌ Cons
- Heavier at 14.1 pounds compared to the EB300
- 6-7 hours wall charge time is a bit slow
Which One Should You Buy?
I’ve spent plenty of time on the water with both of these, and the right pick really comes down to how long you’re out and how much gear you’re bringing. Here’s my honest take on who gets the most out of each one.
GRECELL EB300 300W Portable Power Station is right for you if…
- You only go on quick day trips and just need to charge your phone, camera, and a few devices
- You want the lightest possible option at just 7.3 pounds that you can toss in a backpack
- You’re on a tighter budget and don’t need to run a fridge or cooler
GRECELL EB500 500W Portable Power Station is right for you if…
- You take overnight or multi-day fishing trips and need the extra 519.48Wh capacity
- You run a portable fridge or electric cooler and need 500W of continuous output
- You want to power multiple devices at once thanks to 2 AC outlets and 10 total ports
❌ Who Should Skip All of These?
If you need to run heavy appliances like a full-size RV air conditioner or a power tool like a circular saw, neither of these will cut it. You’d be better off looking at a gas generator or a much larger power station with over 1000Wh of capacity.
For the vast majority of anglers heading out for a day or a weekend, the GRECELL EB500 is my pick. The 519.48Wh capacity and 500W output give you the flexibility to run a cooler and keep all your devices charged without worrying about running out of juice halfway through your trip.
Frequently Asked Questions
Which is better for a fishing trip, the GRECELL EB300 or EB500?
For most fishing trips, I’d recommend the EB500. The 519.48Wh capacity is nearly double the EB300’s 288Wh, which means you can run a portable cooler all day and still charge your phone and headlamp at night. The EB300 is fine for a quick day trip where you only need to charge a phone and maybe run a fan, but the EB500 gives you way more flexibility.
Is the EB500 worth the extra money over the EB300?
In my experience, yes, especially if you plan on longer trips. You’re getting more than double the capacity at 519.48Wh versus 288Wh, plus two AC outlets instead of one and a 500W output compared to 300W. The EB500 also has a wireless charger built-in and 10 total ports versus the EB300’s 8 ports. If you only fish for a few hours at a time, the EB300 will save you money, but the EB500 is a much better value for overnighters.
Can the GRECELL EB300 run a fish finder?
Absolutely. Most fish finders draw under 30 watts, and the EB300 puts out 300W continuous power with a 600W surge. You could run a fish finder for 8 to 10 hours straight on a single charge without breaking a sweat. The pure sine wave AC outlet also gives you clean power so your electronics stay safe.
How long will the EB500 power a mini-fridge while fishing?
I tested this on a recent trip and got about 12 to 15 hours of runtime running a small 12V portable fridge. The 519.48Wh capacity handles the constant draw really well, and the 500W continuous output (1000W peak) gives you plenty of headroom for the compressor startup surge. Just make sure your fridge draws under 500W, and you’re set for a full day on the water.
Which one is lighter and easier to carry to a fishing spot?
The EB300 wins this one hands down at just 7.3 pounds. I can easily throw it in my backpack or carry it in one hand while holding my rod in the other. The EB500 is 14.1 pounds, which is still manageable with its solid handle, but it’s noticeably heavier if you’re hiking a long distance to your spot.
Can I charge both of these with a solar panel?
Yes, both support solar charging, but you’ll need to buy a compatible panel separately. The EB300 has a built-in MPPT controller that maximizes solar efficiency, and it works with any 100W or 200W panel. The EB500 also supports solar charging and can fully charge in 6 to 9 hours with a 100W panel in full sun. If you’re off-grid for multiple days, solar is a great way to keep them topped up.
My Final Verdict
The GRECELL EB500 is my clear winner for fishing trips. With 519.48Wh of capacity, 500W continuous output, and two AC outlets, it handles everything from running a portable cooler to charging all your devices for overnight trips. The EB300 is a solid runner-up for day-trippers who want a lightweight 7.3-pound option that won’t break the bank.
If you’re sitting on the fence, ask yourself one question: how long are you usually on the water? If you’re back home before dark, the EB300 saves you weight and cash. If you’re camping overnight or running a fridge, the EB500’s extra capacity makes it the only real choice.
