Smart Weigh Coffee Scale with Timer, Precision Espresso & Tea Digital Scale, Espresso Machine Accessories for Pour-Over Coffee, Travel Food Scale, LED Display, Rechargeable USB-C - 3kg/0.1g

I’ll second the recommendation from Optimal-Confusion418 regarding the aeropress, but I prefer the Porlex grinder and add a small scale. All of this can fit in two of the Husky document bags. For a travel kettle, any dual-voltage model with multiple temp settings will do.
