Here are a few obscure things that I learned using both Chargepoint and Blink Chargers: Chargepoint chargers have longer cables, about 4 feet longer...I have yet to back into a parking space for a Chargepoint Charger, except one time when the adjacent parking spaces had other ICE cars, but I was able to back into a space that was close enough for the cable to reach my car. Blink chargers have a cord that barely reaches the charge port. If the parking stop prevents the front of the car from being less than 2 feet from the charger, you have to back into the parking space for the cable to reach the Prius charge port. All Blink chargers are currently free in California. Blink intends to charge for charging at a future date, but for now we are lucky. To use a Blink charger, you must sign up for a Blink Card, either by phone or on the Internet -- they are currently free. You can't use the Blink charger until you have the Blink Card. Another credit card won't work. Calling the 800 number won't work. The website says that a Chargepoint charger card is currently $5; however, according to other posts on here you may still be able to get a free card by calling on the phone. You don't need a Chargepoint Card to use a Chargepoint charger, you can call the phone number on the charger, and they will unlock the charge for you. If you have a credit card with a wireless symbol, you can tap the card to unlock the charger. Many Chargepoint chargers have both a level one and level two chargers -- When you unlock the charger, you can either pull the level two charger out of the socket, and plug it into your car, or you can open a door to expose a level one power outlet (a standard 120 V outlet) for you to plug your charger into. You can use both Level One and Level Two charging ports at the same time, if you have two different cards. So you can use the level two charger to charge your Prius, and then unlock the level one outlet, and plug something else in (like a laptop). Chargepoint technical support says you can't do this, but I have done it. Also if some one is using the Level two charger, and you can park in an adjacent space, you can use Level one charger for your car.
