Built for field use
No fluff. Just practical setup notes, power draw estimates, and gear comparisons for people actually using this stuff.
Fridge comparisons
Drawer fridges, chest-style compressor fridges, dual-zone units, and budget vs premium options.
Solar setups
Charging strategies for camp, truck, boat, van, emergency backup, and Starlink-style off-grid systems.

About this project
Real-world 12V refrigeration experience.
12VFridgeFreezers.com is being built as a practical field-notes and testing resource for portable refrigeration systems used in camping, overlanding, off-grid power setups, and adventure vehicles.
Unlike generic review sites, this project is based on real-world daily use from someone actively running both a 12V drawer fridge and a dedicated 12V freezer full-time inside a solar-powered adventure truck.
Topics include battery runtime, LiFePO₄ systems, solar charging, portable power stations, compressor fridge efficiency, off-grid cooking setups, Starlink deployments, and practical camping power management.
The goal is simple: create straightforward, useful information based on actual use — not recycled marketing content.
