Mobile Power Bank
Back in the day, carrying power with you meant having a pocket full of batteries. But sometimes 9-volt batteries would get short-circuited by your pocket change and heat up or explode on your leg, so you had to add potential medical bills to the cost of ownership. Or maybe that was just an urban legend. Either way, a mobile power bank will charge all your electronic devices, and you definitely don’t have to worry about meltdowns. Just way better all around.
