Which is better for all-day cold weather?

The Savior Heat, on paper. It claims up to 10 hours, while the Gerbing runs 7 hours on low and 3 on high. If you need maximum heat rather than duration, the Gerbing's 140F high setting is the stronger choice.

The Gerbing publishes its temperatures: 140F on high, 120F on medium, and 100F on low. Savior Heat does not publish temperatures, so the Gerbing is the safer bet if warmth matters most.

Which lasts longer per charge?

The Savior Heat claims up to 10 hours. The Gerbing gives 7 hours on low, 5 on medium, and 3 on high. Real runtime depends on the setting you use and the cold.

Which has more size options?

The Gerbing offers S/M, L/XL, and XXL. The Savior Heat comes in S through XL, so it has no XXL.
