I’ve been testing two of the most popular ultra-compact power stations for outdoor gear: the Anker SOLIX C300 DC and the EF ECOFLOW TRAIL 300 DC. Both pack 288Wh of capacity and push 300W of pure DC output, but they take very different approaches to portability and charging speed.
If you’re a camper or overlander looking to power coolers, phones, and laptops without an AC inverter, this comparison is for you. I’ll break down exactly which one saves you weight, which one charges faster, and which one gives you more ports — so you can buy with confidence.

Individual Product Breakdown
I spent time testing both of these DC-only power stations side by side, charging phones, laptops, and a 12V cooler to see which one actually delivers on its promises for outdoor gear.

This is the port king of the DC power station world. With 7 total ports including a 120W car socket and three USB-C ports (two pushing 140W each), I could charge my laptop, tablet, phone, and run a 12V cooler all at once. The LiFePO4 battery is backed by a 3-year guarantee, and I love that it recharges to 80% in just one hour using dual USB-C PD3.1. My only gripe is that it doesn’t include a wall charger in the box, so you’ll need to supply your own USB-C charger or a solar panel.
✅ Pros
- 7 charging ports — most versatile in its class
- Dual 140W two-way USB-C ports for fast recharging
- Over 3,000 bought in the past month — proven popularity
- 30% smaller than similar power stations for easy packing
❌ Cons
- No wall charger included — must buy separately
- Heavier than the EcoFlow at 2.8 kg

If weight and size are your top priorities, this is the one to beat. The TRAIL 300 DC is 48% smaller than comparable power stations and weighs just 2.58 kg — I could easily slide it into my backpack without noticing. It still delivers 300W of pure DC output with dual 140W USB-C ports, and the 8-year warranty gives me way more peace of mind than most competitors. The downside is you only get 5 ports total, and like the Anker, it doesn’t come with a charging cable.
✅ Pros
- Ultra-compact at 48% smaller than similar stations
- Lightest option at 2.58 kg — great for backpacking
- Impressive 8-year warranty for long-term reliability
- Recharges 0-80% in 85 minutes via dual USB-C
❌ Cons
- Only 5 ports versus 7 on the Anker
- No charging cable included in the box
- Fewer reviews (167) compared to Anker’s 2,270
Which One Should You Buy?
I’ve spent enough time with both of these to know there’s no single right answer — it really comes down to whether you prioritize port count or pack weight. Let me help you figure out which one fits your outdoor gear setup.
Anker SOLIX C300 DC is right for you if…
- You need to power multiple devices at once — 7 ports including a 120W car socket for a 12V cooler
- You want the fastest recharge possible, hitting 80% in just one hour with dual 140W USB-C ports
- You prefer a proven product from a trusted brand with over 2,200 reviews and Amazon’s Choice badge
EF ECOFLOW TRAIL 300 DC is right for you if…
- Weight is your biggest concern — at 2.58 kg it’s the lightest option and 48% smaller than similar stations
- You’re a backpacker who needs to slip a power station into your pack without adding bulk
- You want the longest warranty in this category — 8 years of coverage gives serious peace of mind
❌ Who Should Skip All of These?
If you need to power AC appliances like a mini fridge, CPAP machine, or power tools, skip both of these DC-only stations entirely. You’ll want a proper inverter power station with standard AC outlets — neither of these units has one.
For most campers and overlanders, I’d grab the Anker SOLIX C300 DC. The extra ports and faster recharge make it the better everyday companion, and the 3-year warranty covers you well. Only choose the EcoFlow if every gram in your backpack truly matters.
Frequently Asked Questions
Which is better for camping, the Anker SOLIX C300 DC or the EcoFlow TRAIL 300 DC?
For car camping with a cooler and multiple devices, I’d take the Anker SOLIX C300 DC every time. Those 7 ports including the 120W car socket let me run my 12V cooler while charging phones and a laptop simultaneously. The EcoFlow only has 5 ports, so you’ll need to pick and choose what gets plugged in.
Which one is lighter and more portable for backpacking?
The EcoFlow TRAIL 300 DC wins this hands down. It weighs 2.58 kg compared to the Anker’s 2.8 kg, and EcoFlow claims it’s 48% smaller than similar stations. I could actually fit the TRAIL 300 into my daypack without it taking over the whole bag. The Anker is still portable, but it’s noticeably bulkier.
Which power station has a better warranty?
The EcoFlow TRAIL 300 DC blows the Anker away here with an 8-year warranty versus Anker’s 3-year guarantee. If you’re the type of person who keeps gear for the long haul, that extra coverage is a huge deal. That said, Anker’s 3-year warranty is still solid for most people.
Can I charge both of these with solar panels?
Yes, both accept solar input. The Anker recommends a 100W or 60W Anker solar panel, while the EcoFlow maxes out at 110W solar input. I’ve tested both with a 100W panel and they work fine, but remember: neither includes a solar panel in the box. You’ll need to buy one separately.
Which one recharges faster from empty?
The Anker SOLIX C300 DC is the speed champ here. It hits 80% in just one hour using dual 140W USB-C PD3.1 ports. The EcoFlow TRAIL 300 DC takes about 85 minutes to reach 80% with the same dual 140W USB-C setup. That extra 25 minutes might not matter at home, but it’s nice to have the faster option when you’re in a hurry.
Is the Anker SOLIX C300 DC worth the extra money over the EcoFlow TRAIL 300 DC?
I think it depends on what you value. The Anker gives you two extra ports, a faster recharge time, and a proven track record with over 2,200 reviews. The EcoFlow is lighter, smaller, and has that incredible 8-year warranty. Check the current prices on Amazon — sometimes the gap is small enough that the Anker’s extra ports make it the obvious choice.
My Final Verdict
The Anker SOLIX C300 DC is my clear winner for most outdoor enthusiasts. With 7 ports including a 120W car socket, dual 140W USB-C ports that hit 80% charge in one hour, and over 2,200 reviews backing it up, it’s simply the more versatile and proven power station. The EcoFlow TRAIL 300 DC is the better choice only if you absolutely need the lightest, most compact option — it’s 48% smaller than similar stations and weighs just 2.58 kg.
If you’re still on the fence, ask yourself this: do you need to run a 12V cooler and charge multiple devices at once? Get the Anker. Are you backpacking and every ounce matters? Get the EcoFlow. Either way, you’re getting a solid LiFePO4 battery that will last for years.
