How much mah need to power up a lunch box ?
I normally charge the powerbank to full anyway.
For your lunchbox, I would think you need to see what kind of input it needs to work, and whether the powerbank can supply that amount? For myself, I don't power up any special items, just phones / tablets / small tools etc. Fast charging tends to heat up the powerbank more. If you're using the box at a specific place, why not just use a normal charger with USB output to the box itself? A normal phone charger etc.
Safety is more on whether the powerbank can cutoff power if it detects an overload, overheating etc? That's why I just stick to more well known brands.....
