When the household power is used
i. Plug the power lead into the household power outlet securely
ii. Plug in the appliance and turn the power on
iii. Good air circulation is necessary for the operation of the fridge. The product must not be blocked or
covered during use
Tips and tricks for electronic refrigerator :
1. The closer to the thermoelectric element inside
the cooler, the better cooling effect is.
2. For very cold drinks, icing effect is better
with aluminum canned drinks.
3. For fresh fruits (e.g. watermelon), cut the fruit
into smaller pieces first, and then cover them
with cling film and put the flat surface close to
the inner wall of refrigerator.
4. For a ready meal, put the meal in a metal dish
first, and then cover it with cling film and put on
the base of the unit close to the inner wall of the
refrigerator.
5. For refrigeration of cosmetic items or skincare
products, put them in the middle or lower shelf,
the closer to thermoelectric cooler, the better
cooling effect is.
Temperature reference for refrigeration
and fresh
1. When items are put into the refrigerator for
cold storage, the temperature in the
refrigerating chamber should be between
3-8°C to keep quality and flavour and
prolong freshness.
2. The colder the ambient temperature is, the
colder the unit will operate internally, for
example a n unheated room would possibly
make the items freeze internally.
3. Recommended to keep the room ambient
above 18°C and below 25°C for best
operation. Ensure ventilation at all times.
When the USB power is used
i. Plug the USB lead into the USB power outlet securely
ii. The fridge will require a USB outlet with a minimum current output of 2A
iii. If using in a vehicle, the engine is required to run to ensure good voltage supply to the fridge
iv. Plug into the USB marked socket on the fridge
v. Good air circulation is necessary for the operation of the fridge. The product must not be blocked or
covered during use.
