Let the hive mind of Engadget get that for you.
"I finally got a new laptop with a lone USB 3.0 port. I'm now looking at getting a USB 3.0 hub with a power adapter so I can use both of my USB 3.0 hard drives at faster speeds. I've read lots of horror stories where some hubs either don't come with power adapters -- and as a consequence the portable drives don't work with them properly -- or they are designed poorly which results in USB 2.0 speeds. Or, the hard drives keep getting disconnected. Do your readers have any suggestions or experience using USB 3.0 hubs? Thanks!"
I dont see the electric car selling like hotcakes ihere in Puerto Rico. The Puerto Rico Power Authority(AEE) currently charges .27 KWH for residential use. in theory, charging your EV at night in PR is going to cost you (that is, if you used this charger at its full 7.24KW capacity) S1.94 Per hour, so presuming you plug it in each night with a presumable 3 hour charge for 30 days were talking about $174.60 per month in aditionl to your regular electrici bill .here is my formula its not perfect but it gives you an idea.
(KWH rate X KWH consumed by charger X hour it takes to fully charge X days of charging)
@Illankid Using your math, $174.60 per month if you drive 100 miles per day. 100 miles per $5.82. So unless you're driving 3,000 miles per month (30 days * 100 miles) on the island, you're not spending $174.60 a month.
@Illankid
3000 miles in a 20mpg car uses 150 gallons of gas. At $2.90 that would be $435 going to support companies that spill oil in the water, require us to send troops to protect oil in the Middle East, spend billions of taxpayers money on subsidies to keep drilling domestically, and throw up a lot of air pollution to move someone around quickly...
@Kermee I forgot to add that a vehicle in a traffic jam will affect its MPG severely we have to wait and see how drastic it is on a electric car.
@rcappo
i hear ya, but if people pay their gas as they use it, not like the electric bill wich comes monthly. this can be an oportunity for the electric company. the other idea would take and additional investement of solar panales and wind generator to "charge" your car for "free".
