Refrigerated top box

I’ve done absolutely no research on this but thought I’d ask in case someone has some relevant experience.

There may be a need for delivery of frozen food products by bike. Anyone know of a specific refrigerated top box as opposed to a bastardised version?

I would wager you could buy one in California

Frozen Blood products are transported by bike using polystyrene containers with dry ice packs inside.
12v cool box with ice packs .

I can think of a few reasons why you may not find one
The power drain is quite heavy on the small 12 volt fridges so the only time you could power it is when the bike is running
If the bikes generator is man enough that is

What about a cool box and some ice packs?
