EcoFlow DELTA Max (2000): Recalled

The DELTA Max (2000) is recalled. CPSC recall 26-010 covers about 25,030 units of model EFD310: they may overheat and ignite, posing a risk of serious burn injury and fire. CPSC lists six reports of fires with property damage totaling over $850,000. The remedy is to stop using the unit and contact EcoFlow for a free repair in the form of a firmware update. The full notice is linked in the recall box above.

How to tell which model you have

The recall covers the unit whose nameplate reads "EcoFlow DELTA Max (2000)", model EFD310. It does not cover the DELTA 2 Max, a current LiFePO4 model, and the DELTA Max (1600) is a different capacity. EcoFlow's US page gives the 2000 version 2,016 Wh, 2,400 W AC output and six outlets on the back (per CPSC).

What the published specs say

The only full spec table found is in the 230 V edition of the manual. It lists NCM (NMC) cells rated for 800 cycles to 80 %+ capacity. That compares directly with the DELTA 2 Max, which EcoFlow rates for 3,000 cycles to the same 80 % threshold — same end point, so the counts can be compared (how makers define cycle life).

Because the US unit has six 120 V outlets and the manual describes a four-outlet 230 V unit, its surge rating, port list and weight are not carried over; this card shows them as not published. EcoFlow's US page gives 1,800 W AC charging (1.8 hours to full) and 800 W of solar input, and the unit took up to two extra batteries for 6,048 Wh.

The calculator can still show what the specs would cover, but do not use a recalled unit until the firmware repair has been applied. Add your appliances to the calculator to compare current models instead.
