Having an extra charger for your Ebike battery is a game changer for commuters and vacationers. Keep your main charger at home, but have an extra charger at your office or to bring with you on trips. I mean, you keep spare cell phone chargers too. This charger will top off you battery even quicker than a standard charger. That way, no matter where you are, you can top off your Ebike's electrons and be ready for the next ride.
