◆MARU heats up or stops working when charging
It is common that MARU heats up when functioning.
Please refer to Instruction "About Auto Reset Fuse".
Before reusing, please check if there is overloadeding
of devices plugged in.
◆ MARU makes noise when device is plugged in
This is a normal situation. The noise comes from the subtle
electric current in the MARU.
◆ Socket outlet sparks when plugged
It is normal for a spark to occur when the plug is in
contact with the socket. Please reduce the time of
intermittent contact to reduce sparks.
Does AC socket support different voltages?
MARU does not transform AC voltage. Devices should
only be used when it supports local voltage.
DC allows voltage from 100 to 240V, which can be
used globally.
Q: Can we use hair dryer with MARU?
A: It depends on if the appliance supports
local voltage.
◆ Why is charing speed slow in TYPE-C socket?
1. It may be that your device or cable doesn't support PD
charging. Please confirm if the device or cable support fast
charging or use OEM cable.
2. Make sure to use the correct port.
LAPTOP port: laptop/higher power 18~45W
MOBILE port: mobile/less power less than 18W
3. If TYPE-C requires higher watts, it is suggested to use
the original transformer to plug in the MARU AC socket.
Power is not stable when charging.
AC: It may be due to overloading, which leads to fuse
disconnect continually. Please remove overload
device, or cut down loading. Try again after 3 mins.
DC: It may be due to poor connection or incompatibility.
Please replug or clean the plug head. If still not
working, please contact us.
