Blackanddecker Charge Uk Laptop Power To Go Cordless AC/USB Power Supply?

Laptop Power To Go Cordless AC/USB Power Supply? - blackanddecker charge uk

Can anyone tell me whether the product is weighted with a power source for an Acer laptop? I'm trying to find a way to buy another for a second battery to extend the battery on my current laptop. Currently takes about two hours. And I wondered if this product would not give me more time to recharge my batteries without. I'm going to college soon and have no access to energy to the battery in the middle of my class to recharge if you die on me. Thank you for your help!
