Ronin’s power bank range includes compact models for casual users and high-capacity charging solutions for people who need extended backup.
The major factors that differentiate Ronin models include:

For example, the Ronin Megawatt R-4055 supports up to 65W charging, while the Zapster R-4040 supports up to 35W fast charging.
However, the actual charging speed depends on whether your smartphone, tablet, or laptop supports that charging standard.
