Power Sharing

Turn your phone into a backup battery with Power Sharing

Power Sharing is a niche yet clever utility from Samsung that turns compatible Galaxy devices into emergency power banks for other gadgets. Used together with the dedicated Power Sharing Cable EP-SG900, it lets you transfer battery charge to accessories such as headsets, cameras, or older phones that rely on a micro USB port.

The core appeal lies in control and safety. Instead of blindly dumping your entire battery into another device, Power Sharing lets you decide exactly how much energy to share. You can define a minimum charge level to keep on the source device, and the transfer automatically stops once that threshold is reached. Start and pause options give you fine‑grained control, helpful when you only want to top up a device just enough to get through the day.

The interface is simple and functional, focusing on sliders and clear indicators rather than fancy visuals. That minimalism makes it easy for anyone to use, even if they are not tech‑savvy. There are no cluttered menus or confusing settings; you adjust your limits and let the app do its job.

However, the app is highly specialized. It works only with Samsung’s EP-SG900 cable, which must be purchased separately and may be hard to find in some regions. Compatibility is limited to devices with a micro USB interface, which makes the tool feel dated in a world now dominated by USB‑C. Depending on your device model and software version, support may also vary.

Overall, Power Sharing is a smart companion for those who already own the compatible cable and still use micro USB gadgets. For that specific audience, it offers a practical and reassuring way to share power without risking a dead primary device.
