Charge an electric outboard from a portable power station

Taking an electric outboard on the dinghy to a bach with no power, or a lake campsite with no hook-up? The catch is size: the battery in an ePropulsion Spirit 1.0 Evo is 1,276 Wh, bigger than most “1 kWh” power stations. A 1 kWh station gives a Spirit battery only about 58%, while a small 378 Wh ePropulsion eLite gets about two full charges. QuietWatt’s honest answer, using the battery and charger ratings ePropulsion and Torqeedo publish.

Step 1: how big the outboard battery is, and what its charger draws

From the maker’s catalogue, manual or spec page (checked 3 Nov 2026). These are not QuietWatt measurements:

OutboardBatteryIncluded AC chargerCharge time (maker)12 V option
ePropulsion eLite (500 W)378 Wh, 25.2 V, built in29.4 V × 4.0 A (about 117 W output)4 h12 V charger: 70 W in, 10–30 V, 7 A max
Torqeedo Travel 1103 C (1,100 W)915 Wh, 29.6 VPower supply (90 W per retailers)10.5 h (manual)12/24 V cable 1128-00: any 9.5–50 V DC source that can give 4 A
ePropulsion Spirit 1.0 Plus / Evo (1 kW)1,276 Wh, 48 V (Spirit Battery Plus)Standard 180 W, or optional fast 520 W8.5 h standard, 3.5 h fastDC/DC charger: 70 W in, 10–30 V, 7 A max (dealer spec)

NZ prices seen 3 Nov 2026: Spirit 1.0 Plus/Evo from NZ$4,190 incl GST and the eLite from NZ$2,490 incl GST at Orakei Marine, which also lists a spare Spirit battery at NZ$1,750 and the fast charger at NZ$478.20; NZ Electric Boat Co. lists the Spirit 1.0 Evo at NZ$4,049 excluding GST. A spare outboard battery is the other way to double your range, so compare it with the price of a station.

Step 2: how many refills one station charge gives (estimate)

Refills ≈ (station Wh × ~0.85) ÷ (outboard battery Wh ÷ ~0.85). The first ~0.85 allows for the station’s inverter losses, the second for the outboard charger’s own losses. Both are planning allowances, not specs, so a 1,024 Wh station has about 870 Wh to give and a 378 Wh battery needs about 445 Wh from the wall to fill.

Station sizeeLite 378 WhTorqeedo 915 WhSpirit 1,276 Wh
1,024 Wh (DELTA 3 Plus, C1000 Gen 2, Elite 100 V2)About 2 full chargesAbout 80% of oneAbout 58% of one
1,070 Wh (Explorer 1000 v2)About 2About 85%About 61%
4,096 Wh (DELTA Pro 3)About 7.8About 3.2About 2.3

What that means on the water (arithmetic on Torqeedo’s own table): Torqeedo quotes the 1103 C at about 6 hours and 18 nautical miles at half throttle, or 50 minutes at full throttle, on a full 915 Wh battery. About 80% from a 1 kWh station is roughly 4¾ hours or 14 nautical miles at half throttle. Range depends on boat, load and conditions, as Torqeedo says.

Step 3: can the station run the outboard charger?

Every 1 kWh-class station below has far more AC output than these chargers need, even ePropulsion’s 520 W fast charger. The limit is Wh, not watts.

Station (official listing)WhAC outputSpirit fast charger 520 WWhat one full station charge does
EcoFlow DELTA 3 Plus (NZ store)1,0241,800 WYesRuns out before a Spirit is full
Jackery Explorer 1000 v21,0701,500 WYeseLite about 4 h on its own charger
Anker SOLIX C1000 Gen 21,0242,000 WYesTorqeedo about 10.5 h, still not full
BLUETTI Elite 100 V2 (AU)1,0241,800 WYeseLite twice over
EcoFlow DELTA Pro 3 (230 V EU listing)4,0964,000 WYesTwo-plus full Spirit charges

Station Wh and AC watts from the linked official listings, as used across QuietWatt’s comparison pages. DELTA Pro 3 AC output as listed by EcoFlow EU; confirm on your local listing. Charge times are the outboard maker’s figures for its own charger; the station does not speed them up. Leave the station’s AC output on for the whole charge and check its AC auto-off setting, or it may switch off partway. The inverter also uses some power just being on, which is part of the ~0.85 allowance.

The 12 V route: slower, but skips the inverter

All three outboards have a 12 V charging option, and each fits under a station’s 10 A car socket: ePropulsion’s eLite and Spirit 12 V chargers both take 70 W with a 7 A maximum, and Torqeedo asks for a source that can supply at least 4 A. Skipping the station’s inverter saves its conversion loss, so more of the station’s Wh reaches the outboard.

The trade-off is speed. At 70 W in, the eLite takes all day (EMO Electric, a US dealer, measured about 13% an hour, so roughly 7–8 hours), and the Spirit’s DC/DC charger outputs only 1 A at up to 52.2 V, so a full 1,276 Wh battery would take well over a day. It suits topping up overnight or while you drive to the ramp. Check your station’s car-socket rating against our 12 V socket table.

eLite day trips

~1 kWh station

About two full eLite charges: a weekend of short runs to the fishing spot.

Spirit or Torqeedo weekend

2–4 kWh, or a spare battery

A 1 kWh station won’t refill one big outboard battery. Price a spare outboard battery against a bigger station.

A week off-grid

Station + solar

Recharge the station from solar between trips: how many solar panels. ePropulsion and Torqeedo also sell solar chargers that go straight to the outboard battery.

Safety notes

  • Use the outboard maker’s own charger. ePropulsion’s eLite manual warns that non-official chargers can damage the equipment.
  • Both makers give a charging temperature range of about 0–45 °C for these batteries. Don’t charge a frozen battery on a frosty morning at the lake.
  • Most power stations are not waterproof. Charge on land or somewhere dry, not in an open dinghy. See small boat and kayak power.
  • Not electrical or marine-safety advice. Check label / listing.

Where to buy (affiliate placeholders)

Tracked affiliate links will replace these placeholders once QuietWatt is enrolled in each program. Until then, use the official product URLs above and confirm the station’s Wh and AC output on the live NZ/AU listing. Confirm your outboard battery’s Wh on its label.
