Wasted $80 on a heated vest that barely lasts an hour
Bought one of those battery heated vests for winter walks. First use it died 45 minutes in. Anyone else had luck with a specific brand that actually holds a charge?
Yeah, I heard a reviewer tear down an Ocoopa battery pack and the cells inside were legit Samsung ones. That makes a big difference over the random no-name cells a lot of brands use. Trusting that internal quality over a cheap price tag has paid off for me more than once.
