About Photovoltaic Energy StorageThe official battery capacity specification provided by RAVPower indicates 85Wh. This translates to approximately 1 hour based on the FilmGrade LED strip power spec of 90W per reel. To temporarily power off, simply click on the power button on the battery pack. When not being used, we recommend unplugging the LED strip completely as a precaution.
About Photovoltaic Energy StorageIf you use a boost converter to get 12V from 5V, then the converter will have to boost the voltage by a factor of 2.4. The current drawn from the 5V supply will go up by that same factor of 2.4. 12V at 0.23A means you will have 0.552A at 5V. That''s ignoring the losses in the converter. In reality, you will need even more current from the 5V supply.
About Photovoltaic Energy StorageHowever, the term "converter" typically refers to an AC to DC converter (or a battery charger), while "inverter" refers to the process of changing DC power to AC power. Because RVs and boats do not always require an inverter, but always have a battery charger, the general term used for the battery charger was the converter.
