Vegetable Cutter Set Portable Wireless Chopper

USB-rechargeable or cordless operation (so it’s truly portable).

Food-grade stainless-steel blades.

Safe materials (BPA-free plastics or good quality ABS/PP plastic).

A container size that suits your needs (if you chop a lot of vegetables vs just garlic/chilli).

Easy cleaning / removable parts.

Clear specification of what “4-in-1” or “multi-function” means (slicing, chopping, mincing, etc).
