What is the biggest difference between the upgraded version and the basic version? Is it worth paying a little more?

The biggest difference is that the new model DHP512 has a built-in battery, allowing you to print anytime and anywhere without connecting to a power source. The battery is fully charged in just 1.5 hours, and you can print 40 photos in a row while the battery is fully charged.
This upgraded photo printer is perfect for anyone who likes to travel and record life on the road, and it's also perfect for family outdoor picnics, no need to look for a power source.
