Let the hive mind of Engadget get that for you.
"As someone who doesn't reside in the USA, I was wondering what would be the best way to get internet for my computer in the US for a couple of weeks? If it were Europe I know I'd look for some prepaid data. Is there anything similar offered by American carriers? A MiFi or a data SIM that I can tether from would work, but I'm trying to maintain a tight budget. Help!"
That title is misleading.
Not entirely; these batteries have more than 5x the power density (relates to how much power can be produced at a time) compared to typical Lithium Ion batteries (1800W/KG compared to 340W/KG). However, the layman would probably equate the word "capacity" with the energy density (relates to how long the power can be produced for).
And for energy density, these batteries are actually poor; the typical range is 100-160, these are 95.
Wups, and in my own haste, I reversed power density and energy density. My bad.
