Why am I getting charged $40 for my short charging session?

You're most likely not. When you first connect your car and present payment, we authorize your payment method for an amount that will cover pretty much any charging scenario. Then, after your are done charging, we adjust the pre-authorized amount to match the amount shown on the payment screen of the charger.

Some credit companies will send notices to you via text or email as soon as we authorize payment and the wording of that notice can sometimes be misleading ... like "EV Trail has charged your card $40".

Give it a couple hours or so to clear up before getting too worried.
