Which is warmer, the ActionHeat or the Savior Heat?

On paper the Savior Heat should run warmer: its 7.4V battery is double the ActionHeat's 3.7V. But Savior Heat publishes no temperature figures, while the ActionHeat tops out at 140F. If you need a guaranteed number, the ActionHeat is the known quantity.

Which lasts longer on a charge?

Savior Heat claims up to 10 hours. The ActionHeat gives 8+ hours on low, 6+ on medium and 4+ on high. Expect real-world times to drop in cold conditions for both.

Is the Savior Heat worth the extra $5?

Only if you want the higher voltage and merino wool. The ActionHeat is $89.99 at Amazon as of November 4, 2026, has published heat levels, an XXL size and a 4.5-out-of-5 rating from 75 ratings. The Savior Heat is $94.99 at Amazon as of November 4, 2026 with no rating count.

Can I machine wash either pair?

The ActionHeat is machine washable on a gentle cycle, but only inside the supplied mesh wash bag, with batteries removed. Savior Heat's listing gives no washing instructions, so check the tag before washing.

Which fits larger feet?

The ActionHeat offers S/M, L/XL and XXL, so it covers bigger feet. Savior Heat stops at XL. Check each brand's size chart against your shoe size before ordering.
