Sanyo KIR-SL2SS Kairo Hand Warmer with Eneloop Batteries and Charger, Silver Review

Average Reviews:

(More customer reviews)Very weak heating -rapid battery use - maximum measured temperature with completely charged batteries was 101 degrees, inside a house, with the room temperature over 70 degrees, made with a Fluke thermocouple sensor.

A single turbo 5 minute session with fully charged batteries caused the battery life indicator to go from charged to "ok to continue using for a short time".

This turbo session keeps the heater on for 5 minutes, to get as hot as it can, which was 101 degrees at the hottest point on the case, measured throughout the heating process.

On the other hand, Sanyo Eneloop NiMH batteries as used in the heater are excellent.They remove an important negative feature of other rechargeable NiMH batteries, which is rapid self-discharge.Eneloops hold their charge well, and the 2000 mAh rating works out to a measured 1700-1800 mAh capacity uniformly across dozens of AA cells, which is better quality control than a lot of other brands of NiMH AA batteries.I have so far not had a defective cell, with over 100 cells, vs over 10% for another line of NiMH AA cells.
