We first heard about Sanyo’s Eneloop rechargeable hand warmers early last year, but apparently it’s taken them this long to make it to the states. There’s a new version, too… The original egg-shaped hand warmer gets warm on one side only (102° F in the low setting to 109° F on high, which they call “Turbo”), runs off a rechargeable lithium ion battery, and you get over 3 hours of heat for a 3 hour charge.
The square hand warmer is the new one; it uses AA rechargeable batteries (Eneloops included) and also functions as a battery charger, which is pretty sweet. It warms up on both sides to 102° F on low and 115° F on high, and you’ll get between 1 and 3 hours of warmth for a 4.5 hour charge. So, it’s not as long lasting as the other model, but it’s heating both sides and using swappable batts, which is a major plus in my book.
Best part about these things is the cheap factor: the one-sided warmer with the integrated battery is $35 (in white or pink), and the two-sided warmer that’s also a charger and includes 2 AA Eneloop rechargeable batteries is only $10 more (in silver or, um, ‘hot’ pink). You’ll find them at the online Sanyo store or “select retailers nationwide.”
