Thank you for your interest in the ChargeTech Portable Power Outlet. Unfortunately, we are not able to provide performance estimates due to the vast variety of devices on the market and their technical specifications. The performance yield of the Portable Power Outlet will ultimately depend on your particular device's power draw.
The charging time will depend on the amount of power the unit you are charging draws from the Portable Power Outlet. For best results, the device you are powering should stay within the Portable Power Outlet's capacity limit of 85 Watts.
We hope one of these options will be an option that will fit your needs. If it doesn’t, please keep in mind that we offer a 30-day Risk-Free trial purchase. We also have a new more powerful version available for pre-order here: https://igg.me/at/plug-portable-battery-pack/x/8787483 Please let us know if you have any further questions!
