Comparison

Whole-home battery vs portable

Updated 9 September 2026

A Powerwall is a wall. A Jackery is a suitcase. Retail pages blur them with the phrase “home backup.” The electrical work, the permits, and the kilowatt-hours are not in the same sport.

Verdict If you want automatic backup of hardwired circuits (furnace blower, well pump, 240 V loads), you are shopping installers and a Powerwall-class battery — 13.5 kWh nominal per Tesla’s public datasheet. If you want a device you can take camping and plug a fridge into, you want a portable station. A 2 kWh Jackery does not become a whole-home system because an ad said “home.”

Order-of-magnitude energy

Tesla lists 13.5 kWh nominal on the Powerwall 3 datasheet. Explorer 2000 v2 is 2.042 kWh. DELTA Pro 3 is 4.096 kWh expandable. One Powerwall is roughly six Jackery 2000 v2 packs on energy alone — before you talk about 240 V, transfer equipment, or the fact that the Tesla is not a carry handle.

Regional Powerwall AC output is not a number to copy from a UK PDF onto a North American panel. Tesla’s UK sheet lists configurable kW ratings up to 11.04 kW; North American interconnection is a different conversation with a licensed electrician.

When a portable still wins

When portable is a stall

If last year’s ice storm took the street for 72 hours and you have an electric well pump or a 240 V air-source heat pump, a 1–2 kWh suitcase is emotional support, not a plan. Look at DELTA Pro 3 (4 kWh class, 120/240 V marketing) or a true installed battery. We are not installers. We are not quoting utility interconnection.
