What's the Difference Between Level 1 & Level 2 EV Chargers?


Episode 1833

Carmine from Chicago, IL

Carmine has an electric vehicle and wants to know what's the difference between level 1 through level 3 charging. Leo says it's the size of the water pipe for the electricity. It uses the same amount of electricity, it just depends on how fast he wants it. The bigger the pipe, the more it costs. So charging an electric car in the middle of the day will cost more than filling it in the middle of the night, when demand is lower. He'll also need special 40 amp circuits and 240v AC plug receptacles to use them. That will require an electrician. It's about $200.

New Balance NX950 GPS Runner

Episode 1300

Gary from Laughlin, NV

Gary picked up a second hand New Balance runner's watch and he needs to get a USB charger for it. Leo says that is where he can go if it uses a proprietary connector. It uses a Pogo pin plug, though, and that means he can't just pick up a third party charger.

If Gary can find out what model number it is, he may be able to go to eBay and pick one up. He should definitely get it from New Balance, though.

Why does it take so long to charge my iPad?

Episode 1101

Adam from Riverside, CA

Larry needs to get a new charger for the iPad. Leo says that the iPad requires 10w of charging and most chargers are only 5w. So he'll need to pay close attention to the amperage. He could use the same 10w charger for both his iPad and phone, because the phone will only take as much juice as it needs. If it takes forever to charge, it means the charger just isn't powerful enough. He can boost the charging time by putting the iPad into Airplane mode.
