DRIFTER_016 Posted April 3, 2020 Report Share Posted April 3, 2020 USB output is 5 volts. The only way is with a DC to DC step up transformer. Look for one like this: https://www.amazon.ca/Step-up-Power-Module-Converter-Connector/dp/B01L6AJS1E Be aware that the process of up-converting uses extra power so you will get lees available power from your bank to charge the battery. You would be better off with something like this. https://www.canadiantire.ca/en/pdp/motomaster-eliminator-750a-lithium-ion-booster-pack-and-power-bank-0111906p.html I have one and it outputs 12 volts as well as having a USB port for charging your phone and other small electronics.

Terry Posted April 3, 2020 Report Share Posted April 3, 2020 Yeah. Most usb is only 2 amps and 5 amps at most And I don’t know how many amps your 5 volt solar unit is, by the time you step up to 12 volts You may not have enough power to drive anything Link to comment Share on other sites More sharing options...

USB3 rises to 900mA max so 4.5W Cheers Edited April 3, 2020 by smitty55 1 Link to comment Share on other sites More sharing options...
