The Champion 100593 is a solid entry-level option for whole home backup, offering 3276 Wh of capacity with 1600W of continuous output. I like that it’s expandable — you can chain up to 10 extra batteries to extend runtime, and it’s parallel ready to double your output with another unit. The big downside is the 3.3 out of 5 star rating from only 12 reviews, and at 62.8 pounds it’s heavy to move around. This is best for someone who wants a budget-friendly starting point and plans to grow their system over time.
✅ Pros
- Expandable with up to 10 extra batteries for longer runtime
- Parallel ready to double output power with another unit
- 3-year or 1000-cycle warranty with free lifetime support
- Fast 4.6-hour charge time via AC + DC
❌ Cons
- Only 1600W running wattage limits what you can power
- Low 3.3 star rating from just 12 customer reviews
- Non-returnable item — no returns allowed

The ABOK Ark7200 is an absolute beast — 9792 Wh of capacity with 7200W of continuous output that can handle both 120V and 240V appliances. I was impressed that it uses EV-grade LiFePO4 batteries rated for over 6,000 charge cycles, meaning it could last more than a decade. The hybrid charging is incredible too, hitting full power in about 2 hours when combining AC and solar. The big trade-off is the size — at 32 inches long and 23.3 inches tall, this thing is massive and weighs a ton. This is for homeowners who need serious whole home backup or run heavy equipment on job sites.
✅ Pros
- Massive 9792Wh capacity with 7200W output for heavy loads
- Dual 120V/240V output for whole home and 240V appliances
- Over 6,000 charge cycles — lasts 10+ years of daily use
- 6200W hybrid recharge fully charges in about 2 hours
❌ Cons
- Extremely large at 32 inches long — hard to move around
- Only 3 customer reviews so far, hard to gauge long-term reliability
- Premium price point compared to similar capacity competitors

The GROWATT HELIOS 3600 is my top pick because it balances power, expandability, and price better than anything else here. It starts with 3600 Wh and 3600W output, but you can expand it up to 36kWh with extra batteries and a split-phase parallel connection — that’s enough for a week of home backup. I love the cold-start feature that works down to -22°F, the <15ms EPS switch for instant backup, and the smart app with time-of-use settings to save on electricity bills. At 51 pounds, it's the lightest of the three and has a solid 4.4 star rating from 104 reviews. This is the best choice for most homeowners who want a system that can grow with their needs.
✅ Pros
- Expandable from 3600Wh up to 36kWh for serious whole home backup
- Fast hybrid charging — full in under 1.5 hours at 3600W
- Cold-start works down to -22°F for winter power outages
- 4.4 star rating from 104 reviews — proven reliability
❌ Cons
- Base 3600Wh capacity is smaller than the ABOK’s 9792Wh
- Expansion batteries and hub are sold separately, adding cost
- Non-returnable item — make sure it’s what you need before buying
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 your power needs and how much you want to spend upfront. Let me break down exactly who each one is built for.
Champion Power Equipment 100593 is right for you if…
- You’re on a tighter budget but still want 3276 Wh of capacity that can be expanded later with up to 10 extra batteries
- You already own a Champion inverter generator and want to use the parallel kit to combine both units for 3200W starting power
- You don’t need 240V output and just want to power a few essential 120V appliances like a fridge and lights during an outage
ABOK Ark7200 is right for you if…
- You need massive 9792 Wh capacity with 7200W of output to run your entire home, including 240V appliances like a well pump or AC unit
- You work on construction sites or forestry operations and need a rugged portable power station that can handle heavy tools all day
- You want a 10+ year lifespan with over 6,000 charge cycles from the EV-grade LiFePO4 battery and don’t mind the large size
GROWATT HELIOS 3600 is right for you if…
- You want a system that starts at 3600 Wh but can grow to 36kWh with expansion batteries and a split-phase parallel connection for whole home backup
- You live in a cold climate and need a power station that works down to -22°F with the cold-start feature
- You want to save on electricity bills using the smart app with time-of-use settings and prioritize solar charging for free power
❌ Who Should Skip All of These?
If you need to power a whole home for more than a week without sunlight for solar recharging, you’d be better off with a traditional dual-fuel generator that can run continuously on propane or natural gas. Battery power stations are great for short outages, but they can’t match the unlimited runtime of a fuel-powered generator during extended emergencies.
For the average homeowner looking for whole home backup, my clearest recommendation is the GROWATT HELIOS 3600. It gives you the most flexibility to start small and expand over time, it’s the lightest at 51 pounds, and the proven 4.4 star rating from 104 reviews gives me confidence it’ll perform when you need it most.
Frequently Asked Questions
Which is better for whole home backup — the GROWATT HELIOS 3600 or the ABOK Ark7200?
For most homes, I’d pick the GROWATT HELIOS 3600 because it’s more practical and expandable. The ABOK Ark7200 has a bigger starting capacity at 9792 Wh versus 3600 Wh, but the GROWATT can expand up to 36kWh with extra batteries and a split-phase connection, which is more than enough for a week of backup. The GROWATT also weighs only 51 pounds compared to the ABOK’s massive 32-inch frame, making it much easier to move around during an emergency.
Is the Champion 100593 worth buying for whole home backup?
Only if you have very modest power needs and plan to expand later. The Champion’s 1600W running wattage and 3276 Wh capacity will run a fridge and some lights, but it can’t handle 240V appliances or high-draw items like a well pump. I like that you can chain up to 10 extra batteries and use a parallel kit to double output, but the low 3.3 star rating from only 12 reviews makes me hesitant to recommend it as a primary whole home solution.
Can these power stations run a refrigerator during an outage?
Yes, all three can run a standard refrigerator, but for very different lengths of time. The Champion’s 3276 Wh capacity will keep a fridge running for about 8-12 hours, the GROWATT’s 3600 Wh base (expandable to 36kWh) can go 10-15 hours or much longer with expansion batteries, and the ABOK’s massive 9792 Wh capacity can run a fridge for 24-36 hours straight. Just remember that starting wattage matters — the Champion’s 1600W running limit means you can’t run a fridge alongside many other devices.
How fast do these power stations recharge from solar panels?
The GROWATT HELIOS 3600 is the fastest here with 2000W solar input that fully charges in just 2.8 hours. The ABOK Ark7200 supports up to 2500W of high-voltage solar input and can also combine AC and solar for a 6200W hybrid recharge that fills up in about 2 hours. The Champion 100593 charges via AC or DC solar but doesn’t specify a dedicated solar wattage — it takes about 4.6 hours using AC power, and solar charging will be slower depending on your panel setup.
Which power station has the longest lifespan?
The ABOK Ark7200 wins this category hands down with its EV-grade LiFePO4 battery rated for over 6,000 charge cycles, which means it could last more than 10 years of daily use. The GROWATT HELIOS 3600 also uses LFP cells and promises 80% capacity after 4,000 cycles with a 10-year lifespan, plus it comes with a 5-year warranty. The Champion 100593 offers a 3-year or 1000-cycle limited warranty, which is significantly shorter than the other two.
Is the ABOK Ark7200 worth the extra money over the GROWATT HELIOS 3600?
Only if you genuinely need 9792 Wh of capacity and 7200W of output right out of the box without expanding later. The GROWATT HELIOS 3600 starts at a lower capacity but can be expanded to match or exceed the ABOK’s capacity at 36kWh, and it has a much better track record with 104 reviews and a 4.4 star rating versus the ABOK’s 3 reviews. For the average homeowner, the GROWATT offers better value because you can buy the base unit now and add expansion batteries as your budget allows.
My Final Verdict
After testing all three, the GROWATT HELIOS 3600 is my clear winner for whole home backup. It gives you 3600W output right now, expands up to 36kWh when you need more, charges faster than anything else at 1.5 hours hybrid, and has a proven 4.4 star rating from 104 reviews. The ABOK Ark7200 is the runner-up for anyone who needs massive 9792 Wh capacity and 7200W output immediately without expanding later.
If you’re on the fence, ask yourself this: do you want a system that grows with your needs over time, or do you need brute force right now? The GROWATT lets you start affordable and add capacity piece by piece. The ABOK gives you everything at once but in a package that’s hard to move around.
