Nice enough shirt but the battery doesn’t stay charged. After charging the required 3 1/2 hours until all four lights are on, I left the battery on the counter and in the morning it was down to three lights, by that evening down to two. Recharged and put into shirt and by noon it wouldn’t turn on due to dead battery.would be 5 stars, but the battery only lasts 45-60 minutes. it is a tiny 5000mah phone charger type battery pack.I had to purchase a larger capacity pack (20,000mah) to get 4-5 hours out of it. I love the shirt overall and not that it can last the full distance of my cycling commute it is even better.should come with at minimum a 10,000mah battery, 20,000mah would be better, 5,000mah doesn't cut it.Batteries don’t last as long as I had expected maybe an hourIt works well. Very useful in really cold weather. Cannot speak to the battery life as I have not used it for more than about 90 minutes at a timeI work outside as a valet parking attendant and bought this shirt for my shift. The description says the lowest setting should last 6 hours, but it’s more like 3. The highest setting lasts about 40 minutes. I bought an extra battery to switch around during the night.It does not warm across the chest, which was implied by the photos. It does, however, warm across the lower abdomen. Across the shoulders and down the spine is where it warms in the back. The most disappointing was how the fabric pilled up on the first day’s wearing. I have been wearing it as a middle layer for 4 days and it looks like it’s 20 years old. Photo below.Bottom line, it does it’s job and warms but the battery is not as good as implied. It’s overpriced for the fabric quality and battery life in my opinion.If I’d known this was made in China, I’d never have bought it!!! The battery barely lasted 2 hours. A lithium battery from China in your pocket of a heated shirt…what can possibly go wrong?!?! Everything!!! We’re not even going to donate it. Will just trash it and look for one made anywhere but China!Works as it should the only bad thing about it is that the battery only last 1 1/2 hours when on high. I purchased a additional battery threw the company's website. Beware the extra battery is $50.00 with shipping.Didn’t like all the graphics on the sleeve and woul like to mak the bright power button which probably eats up a lot of battery lifeHusband loves it, very useful as an underwater when he’s out on his snowmobilebatterie ne ce charge pas
