ENTRY-LEVEL UPS AND SERIES MODE
Precautions when using EF DELTA UPS and series mode
When EF DELTA has UPS or series mode on, EF DELTA’s X-STREAM system supports
an entry-level UPS function. You can use the EF DELTA AC socket while the
device is connected to a wall socket with AC power supply (The AC power comes
from the grid, not the battery). When the grid suddenly loses power, the
device can automatically switch to EF DELTA battery power mode in <=30ms to
ensure your work is not interrupted. Series mode is a multi-level power series
solution developed based on the UPS function.
9 power a free life
It allows users to connect two EF DELTAs in series to get continuous power
that is two times more than a single machine. The principle of using it is
when the power of a EF DELTA is used up, the next machine can immediately
replace it to continue the power supply. This a entry-level UPS function that
does not support 0ms in switching power. Do not connect devices require high
continuing power supply. Otherwise, please run multiple tests to confirm it’s
compatibility before connecting devices, such as data servers and
workstations, with EF DELTA. EcoFlow do not take responsibility for any data
loss or equipment damage caused by customers’ failure in following the
instruction.
1.Entry-Level UPS user guide

a electricity device to EF DELTA turn on the AC switch and automatically enter
the entry-level UPS mode. When the external power is cut off, battery will
immediately supplied power to protect your device.
AC ON/OFF
12V CAR
EF DELTA supports the entry-level UPS function with the switching time of less
than 30ms. In accordance with the UL 2743 standard, the AC output consist of a
double blade, ungrounded configuration. Hence, it is recommended to use the
UPS function of EF DELTA only for temporary emergency usage rather than for
long-term usage. DO NOT use electric appliances with bare metal when charging
to avoid the risk of electric leakage and electric shock. It is recommended
NOT to use the UPS function of EF DELTA for products such as databases,
servers, etc. If you want to use the UPS function for devices that is
sensitive to the switching time, please purchase a professional-grade UPS
system. Please note that EcoFlow is not responsible for any potential data
loss due to the use of UPS function.
2. Series mode user guide (Recommended for power users; all machines must be
fully charged)
Users can connect no more than 2 fully-charged EF DELTAs in series using the
AC charging cable to get continuous power and supply appliances with high
output requirements for up to 1.8 hours. In this mode, do not connect EF DELTA
to the power grid using an AC charging cable, or the overcurrent protection
(<20A) may be triggered. Connect EF DELTA to a home power grid and charge each
EF DELTA separately. We do not recommend you to charge more than two EF DELTA
at the same time. Otherwise, the excessive load may cause damage to the home
power grid. To use this function, you need to set one EF DELTA as the Master
and the others as Serve 1. Connect one AC cable to the AC output port of the
master unit and the other side to the input port of Serve 1. After connecting
the EF DELTA, turn all the AC switches on EF DELTA on to activate multi-
machine series mode. Finally, connect all the appliances to the AC sockets of
the Serve 1. Then you can charge your devices by using EF DELTA and enjoy the
