Wireless charging involves energy conversion, and this can lead to heat being produced as a byproduct. Don't be alarmed if your Rokform wireless vent car charger gets warm during usage. We design our chargers with safety in mind. Our tough all-aluminum construction dissipates heat to prevent the charger and your phone from overheating.

Using charging ports to charge devices draws power from the vehicle's battery. But our wireless charger draws a minimal amounts. If your vehicle's engine is running, your charging phone has a negligible impact on the battery. But it's a good idea to unplug your charger if your car is not going to be in use for a long period.

It's perfectly safe to leave your phone on a charging pad or mat overnight or even longer. Modern smart phone batteries stop charging when full to prevent overheating. But we recommend you take your phone off our wireless vent car charger on hot days or when your car might be in direct sunlight. Overheating in a humid car is still overheating.

We designed our wireless car vent charger for several years of consistent performance. Its rugged aluminum body won't crack or break if dropped, and the powerful MagSafe-compatible magnets hold your phone securely. Rokform stands behind its products with a 2-year guarantee against defects in materials and workmanship.

ROKFORM's air vent wireless car charger is designed to work with MagSafe compatible cases. You should be able to charge your phone with the case on, so long as that case supports MagSafe technology. And if there's a problem with your current case, all our Rokform cases are Magsafe-compatible and use N52 neodymium magnets, the strongest available, to ensure a fast wireless charge.

The powerful MagSafe-compatible magnets in our wireless car vent charger are designed to hold and charge your phone without damage or interference. But we recommend that you keep credit cards and other sensitive magnetic devices away from the magnetic charging plate. Nobody wants to discover their card doesn't work at the checkout line.

A soft, dry cloth is all you need to keep our wireless vent car charger shiny and clean. Gently wipe away dirt and fingerprints and your charger looks good as new. You should never use liquid cleaners or submerge our wireless charger in water! You won't damage the aluminum body, but you could damage its electrical components.
