The EcoFlow DELTA 3 Plus is a 1kWh-class power station from EcoFlow’s DELTA 3 generation, released in September 2024. Compared with the DELTA 2, it adds a near-instant UPS switchover of under 10ms, faster AC charging that fills the battery in about 56 minutes, and expansion up to around 5kWh with extra batteries, all on long-life LiFePO4 cells.

Who the EcoFlow DELTA 3 Plus is for

The DELTA 3 Plus fits homeowners who want a quiet backup for a refrigerator, router and lights during outages, as well as campers and van owners who need serious AC power on the road. The fast UPS function keeps sensitive electronics such as desktop PCs or medical devices running when the grid drops, and solar input allows off-grid recharging. If you only need to charge phones and laptops, a smaller and lighter power bank or station would be easier to carry.

What to check before buying a new EcoFlow DELTA 3 Plus on eBay

North American version: look for a US model with NEMA 5-15 outlets; this suits both the US and Canada.
Bundle contents: some listings pair the unit with solar panels or an extra battery; confirm what you are paying for.
Battery shipping: lithium batteries ship by ground; check the seller’s carrier and the delivery estimate.
Warranty: keep the order record and ask whether the unit qualifies for EcoFlow’s manufacturer warranty; Canadian buyers can read our guide to buying on eBay from Canada for duties and shipping.
