Can a power station run a Aquarium (50 gal, heater + filter)?

RUNNING
120 W
SURGE
150 W
DUTY CYCLE
50%

Short answer: 14 of 14 stations we rate can run it. Heaters cycle ~50% in a heated home. In a cold house during a winter outage, expect closer to 80% — livestock tanks justify LFP chemistry for repeated cycling.

Our read on powering a aquarium (50 gal, heater + filter)

The verdicts above come from two hard gates, not capacity: the inverter must sustain 120W continuously and absorb a 150W startup surge. Capacity only decides how long it runs — we model that at 50% duty cycle with a 15% inverter loss, which tracks real-world results far better than the label-math (capacity ÷ watts) most spec sheets imply.

If runtime is the priority, the EcoFlow DELTA Pro 3 leads at roughly 2.4 days. If you just need this one load covered for the occasional outage, the Jackery Explorer 300 is the least expensive station that clears both gates (Under $300).

FAQ

How many watts does a aquarium (50 gal, heater + filter) use?

A typical aquarium (50 gal, heater + filter) draws about 120W while running and surges to roughly 150W at startup. Heaters cycle ~50% in a heated home. In a cold house during a winter outage, expect closer to 80% — livestock tanks justify LFP chemistry for repeated cycling.

What size power station do I need for a aquarium (50 gal, heater + filter)?

The inverter must sustain 120W continuous and survive a 150W surge. 14 of the 14 stations in our database qualify; the cheapest qualifying class is Under $300 (Jackery Explorer 300).

How long will a power station run a aquarium (50 gal, heater + filter)?

It depends on battery capacity: among qualifying stations, modeled runtimes range from 3.5 hours up to 2.4 days (EcoFlow DELTA Pro 3), assuming 50% duty cycle and 85% inverter efficiency.
