Travel friendly 4x18650 charger

I’m looking for a travel friendly 18650 charger with 4 slots.

I’ve received xtar x4 and is way to big to take it with me everytime, so I’m looking for something smaller in size and weight.
It can have EU power supply or usb (if it’s fast enought to charge them over the night).

Once you opt for a 4 cell charger usually it gets larger because of the LCD screen .

May I suggest 2 x Xtar MC2 chargers using a usb splitter cable so both MC2 can be charged from a single 3A usb adapter

You can arrange them back to back with a rubber band holding them together.

These items should be easy to source in your region.
