My new 1300 spinner shuld arrive today. Great service considering I ordered Sunday night. I currently have two 900 passthrus, a usb charger for my to 78mm and a charger for my two V2 batteries so I have stuff plugged i all around the house. I have readthat the spinners charge pretty fast. And I know on a wall charger they are obviously faster. But I was wondering if I will still get decent charge times via usb on my latop. I have a 900 that I put on charge at around 9pm last night and it is still not fully charged on a 1000mAh wall fob. My other I had on my laptop overnight and am running it as a passthru and it was fully charged this morning. Just don't wanna leave myself high and dry with a bunch of dead batteries.
