I’ve spent time testing three portable power stations in the 300W class: the Westinghouse iGen300s, the Champion Power Equipment 100594, and the GRECELL T300. The Westinghouse packs 296Wh of capacity, the GRECELL offers a 230.88Wh battery, and the Champion is a massive 1638Wh unit that’s in a totally different weight class.
This comparison is for anyone who needs portable power for camping, road trips, or emergency home backup without the noise of a gas generator. The key trade-off is portability versus runtime — and I’ll show you which one fits your life best.

Individual Product Breakdown
I tested each of these power stations on charging speed, portability, and how many devices I could plug in at once. Here’s what I found out about each one.
Westinghouse iGen300s Portable Power Station and Solar Generator
296Wh | 600W Peak | 6.4 lbs | 7 Outlets
- Charges up to 9 devices at a time that can power up to 40 hours of lights...
- HOURS & HOURS OF POWER ON A SINGLE CHARGE: 296 Watt-Hours of Li-Ion Battery...
- LESS WEIGHT, MORE POWER: At 6.35 lb. Lighter Than Jackery with More Watt...
The Westinghouse iGen300s hits the sweet spot for me. At just 6.4 pounds and 296Wh, it’s light enough to toss in a backpack but has enough juice to run a TV for 3 hours or charge a smartphone 14 times. The 7 total outlets — including two 120V household outlets and a USB-C port — make it super versatile for camping or home backup. My only real complaint is the 3.4 out of 5 star rating from customers, which suggests some reliability concerns, and I wish the USB-C was faster than standard.
✅ Pros
- Weighs only 6.4 lbs, incredibly portable
- 7 outlets including 2 AC and USB-C
- Up to 40 hours runtime on low draw devices
- 600W peak power handles startup surges
❌ Cons
- Customer rating is only 3.4 out of 5 stars
- Standard USB-C, not the faster 60W PD

- Expandable: Chain up to 10 expansion batteries (sold separately) to extend...
The Champion 100594 is a beast. With 1638Wh of capacity and 3200W peak power, it can run appliances the other two can’t even touch. I love that you can chain up to 10 expansion batteries to it, and it’s parallel ready to pair with another unit for double the output. But at 40.8 pounds, it’s not something you casually carry to a campsite — this is more for home backup or RV use. The 3.3 out of 5 star rating from only 12 reviews gives me pause, and it’s a non-returnable item which is risky.
✅ Pros
- Massive 1638Wh capacity runs big appliances
- Expandable with up to 10 extra batteries
- Parallel ready to double output power
- 3-year or 1000-cycle limited warranty
❌ Cons
- Very heavy at 40.8 lbs, not portable
- Only 3 total outlets for a unit this size
- Non-returnable item with only 12 reviews
GRECELL T300 Portable Power Station 300W 230.88Wh
230.88Wh | 330W Peak | 60W USB-C PD | 6 Ports
No products found.
The GRECELL T300 surprised me with its 60W USB-C PD port — that’s the fastest USB-C charging of the bunch and it can charge a laptop in no time. It’s the cheapest option here by a good margin, and with a 4.7 out of 5 star rating from 113 reviews, customers clearly love it. The downside is the 230.88Wh capacity is the smallest of the three, so you won’t run a mini-fridge for long. It only has one AC outlet too, which limits what you can plug in.
✅ Pros
- 60W USB-C PD charges laptops super fast
- Excellent 4.7 out of 5 star customer rating
- Competitively priced for the features
- MPPT technology optimizes solar charging
❌ Cons
- Smallest capacity at only 230.88Wh
- Only one AC outlet limits device options
Which One Should You Buy?
I’ve spent a lot of time with these three power stations, and the right choice really comes down to how much weight you want to carry versus how much power you need. Here’s who I think each one is for.
Westinghouse iGen300s is right for you if…
- You need a lightweight 6.4 lb station for hiking or camping and still want 296Wh of capacity
- You want to power up to 7 devices at once including two 120V AC outlets
- You’re looking for a unit that can run a CPAP for 2 nights or charge a drone 6 times
Champion Power Equipment 100594 is right for you if…
- You need serious power with 1638Wh capacity and 3200W peak to run larger appliances
- You plan to expand your system by chaining up to 10 extra batteries over time
- You’re setting up a home backup system and don’t mind the 40.8 lb weight
GRECELL T300 is right for you if…
- You want the best value and a 60W USB-C PD port for fast laptop charging
- You only need to charge phones, tablets, and a laptop for a weekend camping trip
- You prioritize a top-rated product — it has 4.7 out of 5 stars from 113 reviews
❌ Who Should Skip All of These?
If you need to run heavy appliances like a full-size refrigerator or power tools for hours, none of these 300W-class units will cut it. You’d be better off looking at a gas generator or a much larger power station with at least 2000Wh capacity.
For the average buyer who wants portable power for camping or emergency phone charging, my pick is the Westinghouse iGen300s — it gives you the best mix of light weight, solid capacity, and plenty of outlets. If budget is your main concern, grab the GRECELL T300 and don’t look back.
Frequently Asked Questions
Which is better for camping: the Westinghouse iGen300s or the GRECELL T300?
For camping, I’d pick the Westinghouse iGen300s. It has 296Wh of capacity versus the GRECELL T300’s 230.88Wh, plus it weighs only 6.4 pounds and gives you 7 outlets including two 120V AC ports. The GRECELL is cheaper, but if you’re bringing a TV or CPAP machine, the extra 65Wh on the Westinghouse makes a real difference.
Is the Champion 100594 worth the extra money over the Westinghouse iGen300s?
Only if you actually need the power. The Champion 100594 has 1638Wh of capacity — that’s over five times the Westinghouse’s 296Wh — and it can hit 3200W peak power. But it weighs 40.8 pounds, which is more than six times the Westinghouse’s 6.4 pounds. If you’re just charging phones and a laptop for a weekend trip, the Westinghouse is the smarter buy. If you need to run a mini-fridge or power tools, the Champion justifies its price.
How many hours will each power station run a CPAP machine?
Based on the specs, the Westinghouse iGen300s claims it can run select CPAP devices for up to 2 nights. The GRECELL T300 with its 230.88Wh capacity should get you roughly one night depending on your machine. The Champion 100594 with 1638Wh could run a CPAP for multiple nights straight — probably 5 to 6 nights on a single charge — but you’ll have to haul that 40.8 lb unit with you.
Which power station has the fastest USB-C charging?
The GRECELL T300 wins this hands down with its 60W USB-C PD port. That’s three times faster than the standard USB-C on the Westinghouse iGen300s. If you need to charge a modern laptop quickly, the GRECELL cuts charging time by more than half compared to the other two. The Champion 100594 doesn’t even list USB-C specs on its main product page.
Can I add more battery capacity to any of these power stations?
Only the Champion 100594 is expandable. You can chain up to 10 expansion batteries to it, which is great if you want to start small and build up over time. The Westinghouse iGen300s and GRECELL T300 are fixed at 296Wh and 230.88Wh respectively — what you buy is what you get. If expandability matters to you, the Champion is the only choice here.
Which one has better customer reviews: Westinghouse, Champion, or GRECELL?
The GRECELL T300 is the clear winner with a 4.7 out of 5 star rating from 113 reviews. The Westinghouse iGen300s sits at 3.4 out of 5 stars from 784 reviews, which is a lot of feedback but not great scores. The Champion 100594 has only 12 reviews with a 3.3 out of 5 star rating, so it’s hard to draw strong conclusions there. If customer satisfaction matters most, the GRECELL is the safest bet.
My Final Verdict
My clear winner is the Westinghouse iGen300s. At just 6.4 pounds with 296Wh of capacity and 7 outlets, it hits the perfect balance of portability and power for most people. The GRECELL T300 is the runner-up and best for budget buyers who need fast USB-C charging, while the Champion 100594 is only for those who absolutely need 1638Wh and can handle the 40.8 lb weight.
If you’re on the fence, ask yourself one question: are you carrying this to a campsite or parking it in your garage? If you’re carrying it, get the Westinghouse. If it’s staying put for home backup, the Champion makes more sense.

This is my top pick for anyone who wants a lightweight 6.4 lb power station with enough juice (296Wh) to charge phones, run a TV for 3 hours, or power a CPAP for 2 nights — all from 7 different outlets.

Best for home backup or RV use where weight doesn’t matter — the 1638Wh capacity and 3200W peak power let it run bigger appliances, and you can chain up to 10 expansion batteries later.
Best Budget: GRECELL T300
No products found.
Perfect for budget-minded campers who need fast 60W USB-C laptop charging and don’t mind the smaller 230.88Wh capacity — it’s the cheapest option here with the highest customer rating at 4.7 out of 5 stars.
