Audrey travels for business three to four days a week and is not always near power outlets. She needs a solution for when her laptop battery dies. What would you recommend she do?

a. Purchase a extra laptop

b. Purchase a portable battery bank made to charge laptops.

c. Purchase an extra power cord.

d. Change the power settings on her laptop to consume less power.

b). Purchase a portable battery bank made to charge laptops.

Purchase an extra laptop battery.

Explanation:

Purchasing a new laptop is not a rational option since the laptop is still very functional but not near a power outlet. Every laptop battery needs a power outlet to charge so buying a new laptop will still pose the same problem.

Purchasing an extra power cord will not charge the battery, as a power cord requires a power outlet to work.

Change the power setting on her laptop to consume less power seems reasonable but doesn't solve the problem of what to do when the laptop battery dies. Therefore the best options are:

Purchase a portable battery bank made to charge laptops.

Or

Purchase an extra laptop battery.
