Bounce house blower on a portable power station

Birthday party in a park, a school fair with no outlet near the field, or a bouncy castle at the far end of the lawn? An inflatable needs its blower running the whole time anyone is on it. That makes it one of the hungriest jobs you can give a battery: roughly 800–1,300 W, nonstop. A big station can do a short party; it is not an all-day rental power source. QuietWatt’s honesty, using Zoom Blowers’ own published figures.

Step 1: what a bounce house blower actually draws

From the Zoom Blowers XLT instructions (spec table), nominal 120 V blowers. These are Zoom’s ratings, not QuietWatt measurements. “With BP” means with back pressure, i.e. attached to the inflatable’s tube, which is how you run it:

  • ZM-XLT-1 (1 HP): 778 W / 6.99 A attached to an inflatable; 1,105 W / 10 A with no back pressure.
  • ZM-XLT-15 (1.5 HP): 892 W / 7.8 A attached; 1,102 W / 9.5 A without.
  • ZM-XLT-2 (2 HP): 1,140 W / 9.88 A attached; 1,517 W / 13 A without.
  • ZM-XLT-3 (3 HP): 1,293 W / 11.3 A attached; 2,100 W / 18 A without.

Zoom’s manual also says to leave the blower running the entire time the inflatable is in use, to plug into a GFCI (RCD) outlet, and not to run it in rain or strong wind. Zoom does not publish a motor start-up (surge) figure, so give yourself headroom: pick a station whose continuous AC rating clears the no back pressure number and whose surge rating is well above it — see peak vs continuous watts.

NZ / Australia: Zoom’s XLT line is a 120 V product. Blowers sold here are 230–240 V and have their own rating plates; read yours and match a station with 230–240 V AC outlets — NZ 240 V power stations. Small home-use bouncy-castle blowers are often lower than the commercial figures above. QuietWatt won’t guess them.

Step 2: how many hours of bouncing (estimate)

Hours ≈ (station Wh × ~0.85) ÷ blower watts attached. The ~0.85 is a planning allowance for inverter losses, not a spec.

Worked examples (arithmetic only, Zoom figures): a 1 HP blower at 778 W on a ~1,000 Wh station: 850 ÷ 778 ≈ about 1 hour. The same blower on a ~2,000 Wh station: 1,736 ÷ 778 ≈ about 2 hours 15 minutes. A 1.5 HP blower at 892 W on ~2,000 Wh: about 1 hour 55 minutes. A plug-in watt meter on your own blower beats any estimate.

Short party slot

~1–2 kWh

An hour or two of bouncing with a 1 HP blower. Needs ~1,800 W continuous class or better, not a small camping pack.

Afternoon event

Expandable station

3–4 hours wants roughly 3–4 kWh: an expandable station with extra batteries — expandable stations.

All-day hire / big slide

Wrong tool

8 hours at ~800–1,300 W is 6–10 kWh. Use a mains outlet or a generator — quiet generator vs station.

Estimates / planning only. Blower figures are Zoom Blowers’ published ratings; station Wh and outputs come from official listings. Check label / listing.

Step 3: keep the castle up

  • If the battery dies, the inflatable deflates with kids on it. Watch the percentage, and get everyone off well before it runs flat. Don’t plan to run to 0%.
  • Pure sine output suits the induction motor — pure sine wave.
  • Keep it dry. Zoom says no use in rain or strong wind; most stations aren’t weather-rated either. Shade the station, keep it off wet grass, and keep cords out of the bounce zone.
  • Recharge between slots from mains or solar; solar alone won’t keep up with a ~800 W blower — how many solar panels.
  • Short cord runs. Put the station by the blower rather than running a long thin extension lead — extension lead notes.

Stations QuietWatt already cites (confirm listing)

Roles only. Small packs like the RIVER 3 class can’t run these blowers at all. Confirm continuous W, surge W, pure sine, AC voltage for your region, and Wh on the live listing before you buy.

  • BLUETTI Elite 100 V2 — 1,024 Wh, 1,800 W AC, 3,600 W surge per BLUETTI’s listing and manual; about an hour with a 1 HP blower.
  • Anker SOLIX C1000 — 1,056 Wh, 1,800 W AC; similar one-hour class.
  • BLUETTI AC180 — 1,152 Wh, 1,800 W class; a little more time than the 1 kWh packs.
  • Jackery Explorer 2000 v2 — 2,042 Wh, 2,200 W AC, 4,400 W surge per Jackery’s page; the ~2-hour party size.
  • EcoFlow DELTA 3 Plus — expandable with extra batteries for longer events; confirm output and expansion on listing.
