What Will a 600 Watt Power Station Run?
ZacharyWilliamShort answer: a 600W portable power station can run most small electronics (laptops, Wi‑Fi routers, CPAP, fans, LED TVs, camera chargers) and some kitchen tools (blenders) — but not high‑draw appliances like microwaves, hair dryers, or coffee makers. Below you’ll find realistic runtimes, what to avoid, and a buyer checklist.
What “600W” really means
“600W” is the continuous AC output the inverter can supply. Many units also specify a short‑duration surge (or peak) rating (often around 1,200W) to handle startup spikes from devices with motors or compressors.
- Continuous (rated) power: up to 600 watts nonstop.
- Surge (peak) power: short bursts (e.g., 1–3 seconds) to start devices that momentarily draw more than their running watts.

Battery capacity: measured in
Wh(watt‑hours) — this is what determines runtime, not the 600W figure.
Tip: If your device says 120V × 5A = 600W it’s right on the limit — leave headroom for spikes or pick a higher‑watt model.
What a 600W station will run
Typically OK (individual devices)
- Laptops, tablets, phones
- Wi‑Fi routers, cable modems
- CPAP machines (humidifier off uses less power)
- LED TVs (32–55″), streaming sticks
- Box/desk fans, LED lights, projectors
- Camera battery chargers, drone chargers
- Small kitchen tools like a blender (short use)
Usually not OK
- Microwaves, toaster ovens, kettles, coffee makers
- Hair dryers, space heaters, hot plates
- Full‑size refrigerators (starting surge often too high)
- High‑amp power tools (table saws, air compressors)
These often draw 800–1,800W (or more), exceeding a 600W inverter.
How long will it run? (runtime table)
Use this simple estimate: Runtime (hours) ≈ Battery Wh × usable% × inverter efficiency ÷ Device W.
Example below assumes a ~596Wh battery, ~90% usable, and ~85% inverter efficiency → effective energy ≈ 455.9Wh. Real‑world runtimes vary with temperature, speed settings, and cycling loads.
| Device (typical draw) | Est. runtime (hours) |
|---|---|
| Wi‑Fi router (~10W) | ≈ 45.6 h |
| Laptop 13–15″, working (~60W) | ≈ 7.6 h |
| CPAP (no humidifier, ~40W) | ≈ 11.4 h |
| CPAP (with humidifier, ~70W) | ≈ 6.5 h |
| Portable mini‑fridge (average ~60W, cycles) | ≈ 7.6 h (continuous); ~15 h if 50% duty cycle |
| LED TV 55″ (~80W) | ≈ 5.7 h |
| Box fan, medium (~35W) | ≈ 13.0 h |
| Camera battery charger (~20W) | ≈ 22.8 h |
| Cordless drill charger (~120W) | ≈ 3.8 h |
| Blender (~300W) | ≈ 1.5 h (blenders are used in short bursts) |
Note on surges: Devices with motors (fridges, pumps, fans) can momentarily pull 2–3× their running watts at startup. A 600W station with a 1,200W surge rating can often handle small motor appliances if their running watts are well under 600W and their startup surge is brief.
What it won’t run
- Anything over 600W continuous (e.g., 900W coffee maker, 1,200W hair dryer).
- Appliances with high startup surges that exceed the station’s peak (e.g., some fridges, AC units).
- Multiple medium‑draw devices at once that sum above 600W.
Real‑world scenarios
- Work‑from‑cabin: laptop (60W) + router (10W) + 27″ monitor (30W) → ~4.6 hours.
- Camping night: CPAP (40W) + phone (5W) + LED lantern (5W) → ~9.1 hours.
- Tailgate: mini‑fridge avg (60W) + speaker (20W) + LED strip (10W) → ~5.1 hours.
- Emergency: router (10W) + two LED bulbs (2 × 9W) → ~16.3 hours.
Buyer checklist for 600W class stations
- Battery chemistry: LiFePO₄ for long cycle life and safety.
- Surge rating: look for ~1,200W (or more) if you’ll power small compressors/fans.
- Ports you need: number of AC outlets, 12V car socket, USB‑C PD (65W+ ideal).
- Recharge speed: AC fast‑charge & solar input (200–240W is great in this class).
- Weight & size: if you plan to carry it often.
- Warranty & support: look for multi‑year coverage and accessible support.
Example model : UDPOWER C600
As a concrete reference in the 600W class, the UDPOWER C600 Portable Power Station pairs a 596Wh LiFePO₄ battery with a 600W pure‑sine inverter and 1,200W surge. Highlights include:
- Cycle life: 4,000+ cycles to 80%+ capacity.
- I/O: 2× AC outlets (120V/60Hz), USB‑C PD 65W + Type‑C 35W, 2× USB‑A 18W, 12V car socket.
- Recharge: AC fast‑charge (~1.5h) and up to 240W solar input.
- Form factor: ~12.3 lbs; approx. 11.1″ L × 6.1″ W × 9.4″ H.
- Warranty: 5‑year coverage.

Quick FAQ
Can a 600W power station run a refrigerator?
It can run some mini fridges whose running watts are well under 600W, if the startup surge stays within the unit’s peak rating. Full‑size fridges usually draw too much surge for a 600W inverter.
How many devices can I run at once?
As many as you have ports for — as long as their combined watts stay below 600W continuous and you leave some margin for spikes.
Will it power my CPAP overnight?
Often yes. With humidifier off (~40W), a ~596Wh unit can last roughly 10–12 hours depending on pressure settings and efficiency.
How do I estimate runtime for my device?
Use: Runtime ≈ Effective Wh ÷ Device W. Effective Wh is your battery Wh times usable percent (e.g., 90%) times inverter efficiency (e.g., 85%).
