A battery charger is a device designed to keep your electronic devices from going dark. It may not be the sexiest accessory, but without it you’d be eating up AAs like they’re chocolate chip cookies. The battery charger trend is all about keeping everything from your electric vehicle to your earbuds juiced up and ready to roll. The direction is towards more efficient and eco-friendly charging options, with a focus on smartphones and portable devices. From solar installation to charging stations, the battery charger trend is keeping us plugged in and powered up. Sure, we may be addicted to our screens, but we can’t deny that a well-charged battery makes all the difference in the world – and this trend is making sure we never have to face the dreaded 1% battery life notification.
