The TC21 - an Excellent Product
June 27, 2020
This Peltier cooler is the best I have found, and I am an engineer working on thermal devices. Efficient, quiet, well insulated, and self-adjusting to preserve power when it reaches the desired set point. Great for camping with the least battery drain possible. Dr. Jim.
ConsAn internal LED when open would be really nice...
Best UsesCamping cooler
Medication and insulin cooler (will not freeze)
