I’ve been testing two very different lightweight power stations: the LIBRIDS C600 with its 640Wh capacity and 600W output, and the GRECELL EB300 that packs 288.6Wh with 330W of continuous power. The choice comes down to how much weight you’re willing to carry versus how much power you actually need.
This comparison is for anyone who wants a portable power station that won’t break their back or their budget. The LIBRIDS C600 gives you double the capacity but the GRECELL EB300 is lighter and cheaper — let me help you figure out which one makes sense for your adventures.

Individual Product Breakdown
I spent time testing both of these portable power stations side-by-side, checking how fast they charged, how much they could actually power, and how easy they were to carry around.

The LIBRIDS C600 impressed me right out of the box with its solid metal frame — it feels built to last. I love that it charges from empty to full in just 1.5 hours, which is incredibly fast compared to most power stations in this class. The 640Wh capacity easily ran my CPAP machine all night and still had juice left to charge my phone and laptop the next day. My only real complaint is that at this size and weight, it’s not something you want to hike with — it’s better suited for car camping or home backup.
✅ Pros
- 640Wh LiFePO4 battery rated for 4000+ cycles — lasts years longer than standard batteries
- Full charge in only 1.5 hours, so you’re never waiting long
- 10ms UPS switching keeps your gear running during power outages
- 4 AC outlets plus USB ports let you power 8 devices at once
❌ Cons
- Heavier than the GRECELL EB300, not ideal for backpacking
- No wireless charging pad or 60W USB-C PD port

The GRECELL EB300 is the lightweight champion here at just 7.94 pounds, and I really appreciated the built-in wireless charging pad on top — it’s a small feature but super convenient for topping off my phone at camp. The 60W USB-C Power Delivery port charged my MacBook at full speed, which is rare at this price point. That said, the 288.6Wh capacity is pretty limited — I got about 3.5 hours running a 32-inch TV, so don’t expect to run a mini-fridge all weekend. It’s perfect for a night or two of camping, but not for extended off-grid trips.
✅ Pros
- Only 7.94 pounds with an ergonomic handle — super easy to carry anywhere
- 60W USB-C PD port charges laptops at full speed
- Wireless charging pad built right into the top surface
- Detachable 3W LED light with strobe and SOS modes
❌ Cons
- Only 288.6Wh capacity — won’t power larger appliances for long
- Recharges slowly from a wall outlet (6-7 hours to full)
- No UPS functionality for backup power during outages
Which One Should You Buy?
I’ve spent enough time with both of these power stations to know that the right pick depends entirely on what you’re actually planning to power. Here’s how I’d break it down based on your real-world needs.
LIBRIDS Portable Power Station C600 is right for you if…
- You need to run a CPAP machine or medical device all night — the 640Wh capacity gives you plenty of runtime
- You want home backup protection with the 10ms UPS switch that kicks in instantly during an outage
- You’re car camping or road-tripping and want to power multiple devices at once with the 4 AC outlets
GRECELL EB300 Portable Power Station is right for you if…
- You’re backpacking or hiking to your campsite — at just 7.94 pounds, it won’t weigh you down
- You need to charge laptops and phones fast with the 60W USB-C PD port and built-in wireless charging pad
- You only need power for a night or two — the 288.6Wh capacity handles a TV for 3-4 hours or charges a phone 20+ times
❌ Who Should Skip All of These?
If you need to run power tools, a full-size refrigerator, or any appliance pulling over 600 watts continuously, neither of these will cut it. You’d be much better off looking at a gas-powered inverter generator or a larger power station with 1000+ watt hours of capacity.
For most casual campers and occasional home backup users, I’d grab the LIBRIDS C600 — the extra capacity and fast 1.5-hour charging make it worth the weight. But if you’re hiking into your campsite, the GRECELL EB300’s 7.94-pound frame is the clear winner for lightweight use.
Frequently Asked Questions
Which is better for CPAP machines — the LIBRIDS C600 or the GRECELL EB300?
The LIBRIDS C600 is the clear winner for CPAP users. With 640Wh of capacity, it’ll run a standard CPAP machine all night long without breaking a sweat. The GRECELL EB300’s 288.6Wh might get you through one night if your machine is efficient, but you’d be cutting it close. Plus, the LIBRIDS has that 10ms UPS feature that keeps your machine running during power outages, which is a lifesaver if you rely on it for sleep apnea treatment.
Is the LIBRIDS C600 worth paying more than the GRECELL EB300?
It depends on what you need, but for most people, yes. You’re getting more than double the capacity (640Wh vs 288.6Wh) and the LIBRIDS charges fully in just 1.5 hours compared to the EB300’s 6-7 hours from a wall outlet. If you only need power for a single overnight trip and want to save money, the GRECELL EB300 gets the job done. But if you want something that can handle multiple days or backup emergencies, the LIBRIDS C600 is absolutely worth the extra cost.
Which one is lighter and more portable for backpacking?
The GRECELL EB300 wins this category hands down at just 7.94 pounds with an ergonomic carry handle. The LIBRIDS C600 is heavier thanks to its metal frame and larger battery, so it’s not something you’d want to carry miles into the backcountry. For car camping or RV trips, the LIBRIDS is fine. For hiking to your campsite, the GRECELL EB300 is the only real choice here.
Can the GRECELL EB300 power a mini-fridge?
It can, but not for very long. The EB300’s 288.6Wh capacity will run a small 12V mini-fridge for maybe 4-6 hours depending on the model. The LIBRIDS C600 with its 640Wh capacity will keep that same fridge running for closer to 10-12 hours. Neither one is ideal for full-time off-grid living, but the LIBRIDS is much better suited for keeping food cold over a long weekend.
Which one has better charging options — solar, car, wall?
Both support three-way recharging from wall outlets, car ports, and solar panels, but the LIBRIDS C600 is significantly faster. It goes from empty to full in 1.5 hours on AC power, while the GRECELL EB300 takes 6-7 hours from a wall outlet. The EB300 does have an MPPT solar controller that optimizes solar charging, which is nice, but the slow AC charging is a real downside if you need to top up quickly between uses.
Is the LIBRIDS C600 quiet enough for indoor use during power outages?
Absolutely. Both of these power stations are completely silent since they’re battery-powered — no engine noise like a gas generator. The LIBRIDS C600 has a smart cooling fan that kicks on under heavy loads, but it’s barely noticeable. I’ve used mine indoors during outages to power my WiFi router and CPAP machine, and you can’t hear a thing. Just keep in mind that LIBRIDS labels it for indoor use only in dry conditions, so don’t leave it out in the rain.
My Final Verdict
The LIBRIDS C600 is my clear winner for anyone who wants a power station that can actually handle real appliances and multiple devices. With 640Wh of capacity, 1.5-hour fast charging, and a 10ms UPS for home backup, it gives you way more versatility than the GRECELL EB300 without being too heavy for car camping. The GRECELL EB300 is the better pick if you’re hiking to your campsite and need something at just 7.94 pounds, but its 288.6Wh capacity limits what you can actually run.
If you’re stuck between the two, ask yourself this: are you carrying it on your back or driving to camp? If you’re driving, get the LIBRIDS C600 and never worry about running out of power. If you’re hiking, the GRECELL EB300’s lighter weight makes it the practical choice.
