To charge PHOENIX 200/300 Power Stations, please connect the E.FLEX 50’s MC4 Connectors to the DC
Input Port of the PHOENIX 200/300 Power Station using the included MC4 to 5.5mm DC Adapter Cable.
The E.FLEX 50 will begin to charge the PHOENIX 200/300 Power Station automatically and one of the
Battery Level LED Indicators on the PHOENIX 200/300 Power Station will flash to indicate the current
battery level.
- 05 -

CAUTION Please place the PHOENIX 200/300 Power Station in the shade to prevent it from overheat-
ing.
The E.FLEX 50 can charge rechargeable power supplies from other manufacturers as long
as they accept 18V DC input. The included 5.5mm DC Adapter Connectors may be used with
the MC4 to 5.5mm DC Adapter Cable to connect the E.FLEX 50 to the rechargeable power
supply. Please follow the instructions provided by the manufacturer of the rechargeable
power supply.
NOTE
To charge smart phones, tablets, action cameras, or other USB enabled devices, please connect the
device to the E.FLEX 50’s USB-A Port using a USB charging cable (not included).
To charge handheld gaming consoles, DSLR cameras, or other USB-C enabled devices, please slide the
Slide Switch to the left position and connect the device to the E.FLEX 50’s USB-C Port using a USB-C
charging cable (not included).

CAUTION Please check the voltage rating of the laptop before charging it. DO NOT charge laptops with
voltage ratings other than 16V and 19V. Doing so may damage the laptop.
The USB-C Port of the E.FLEX 50 does not support the Power Delivery (PD) protocol and
cannot charge USB-C laptops.
NOTE
It is highly recommended to shut down the laptop or put it into sleep mode before charging it.
The DC Output Port of the E.FLEX 50 may turn on and off frequently if the laptop runs at full
capacity while charging.
NOTE
To charge laptops, please first select the output voltage of the DC Output Port based on the voltage rating
of the laptop. Slide the Slide Switch to the middle position for 16V DC output and the LED Indicator 1 will
illuminate blue. Slide the Slide Switch to the right position for 19V DC output and both the LED Indicator1
and LED Indicator 2 will illuminate blue. Then, connect laptop to the E.FLEX 50’s DC Output Port using the
included 5.5mm DC to 5.5mm DC Power Cable and 5.5mm DC Adapter Connectors.
To charge batteries, please first connect the MC4 Connectors of the E.FLEX 50 to the PV terminals of a
charge controller (not included) using adapter cables (not included). Then, connect the BATT terminals of
the charge controller to the battery terminals using tray cables (not included). Lastly, set the charging
parameters on the charge controller properly. The E.FLEX 50 will begin to charge the battery automatically
and the real-time battery level will be displayed on the LCD screen of the charge controller.

TROUBLESHOOTING
CAUTION DO NOT connect multiple E.FLEX 50 in series. Doing so may cause irreversible damage to
the E.FLEX 50.
To expand the output power, please connect multiple E.FLEX 50 in parallel by joining the female and male
MC4 Connectors of each E.FLEX 50 together with MC4 parallel branch connectors (not included).
If the E.FLEX 50 does not charge the device connected to it, please check the connection between the
E.FLEX 50 and the device. If all the connections are solid, please check if the Slide Switch is in the correct
position.
If the output port of the E.FLEX 50 turns on and off frequently during the charging process, please check
if the E.FLEX 50 is receiving enough sunlight and if the device is drawing a large amount of power from
the output port. The E.FLEX 50 cannot deliver more power to the device than the amount of solar power
it has captured.
If both the LED Indicator 1 and LED Indicator 2 illuminate red, one or more output ports of the E.FLEX 50
have been shut off due to over-current or short-circuit. Please connect only the devices that conform to the
specifications of output ports or remove the short circuit.
