When it comes to portable power stations, I’m inclined to say that the ability to store and carry with you a significant amount of energy is priceless. But of course these days you can put a price tag on nearly anything. With portable power stations, that’s usually about $1/watt and $1/watt-hour, at least with the big names in the industry. But with the introduction of several new competitors to this growing industry, units like the VTOMAN Jump 1500 and its expandable auxiliary battery are helping lower prices on these convenient new forms of energy storage.
