Two of these 12/24V lithium battery chargers really aren't! It makes me wonder if they're part of the reason they were selling off the product these were in at a really low price. (Hi-viz vests with LED strips.) I wonder what the story behind these is. Were they bought separately for shipping with the product or were they sourced by an offshore manufacturer? Either way, the proper one has been substituted with random look-a-likes that have VERY different circuitry inside and have very little in the way of current limiting. Especially if an attempt is made to use them with 24V as implied on the label. The product itself has it's own video. It's notable for having a three cell 2000mAh lithium battery in thin heat shrink sleeving at waist height on clothing aimed at construction workers. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty. #ElectronicsCreators
