It's even more helpful when it adds extra roadside features like tire inflation, device charging, and emergency lighting. It's a smart thing to keep in the trunk for everyday commuting, road trips, camping, bad weather, and general peace of mind.Thanks to Walmart's Summer Deals sales event, the Amener Car Jump Starter is available for just $50 right now.
