Wireless Reverse Charging

Review by eFreeware

Wireless Reverse Charging is a small Android utility from the developer Masivapp, listed on Google Play under Libraries & Demo. It is free, rated Everyone, and it has been installed more than 500,000 times, with a 3.8 average from around 5,400 ratings. The idea it sells is simple: instead of hunting for a cable, you let one phone lend power to another across the back of the two handsets.

That is the main reason to consider it. Phones have quietly become power banks for each other, and an app that walks you through the exchange has obvious appeal for anyone who has watched a battery drop while a friend's phone sat at 80 percent. What matters is whether the app does anything beyond what the hardware already handles on its own, and the answer is mostly about guidance and a compatibility check.

A cable-free top-up between two handsets

The core job is transferring and receiving electric power between two phones. You set the two devices back to back, with one resting on the rear face of the other, and the process begins. The developer frames this as exchanging power in a few easy steps, which is roughly how wireless power sharing works on handsets that support it.

Where the app adds something is the compatibility check. Before you start rearranging phones on a table, you can confirm whether wireless charging is supported at all. That is a small thing, but it saves the awkward minute of pressing two handsets together and waiting for a sign that never comes.

I would treat this as a companion rather than a replacement for whatever your phone already does. If your handset handles reverse charging natively, the app is a shortcut to the same result. If it does not, no app can add the coil your hardware lacks, and the compatibility checker is the honest part of the package.

Checking a phone before you rely on it

The charging checker is the feature I would reach for first. It answers a question that comes up whenever someone buys a phone, borrows one, or considers a wireless pad: does this device charge without a cable? Having that answer in a free download is convenient, and it is the sort of check worth running before a trip rather than during one.

The developer lists the checker as one of the app's abilities and notes that more features are planned. That framing suggests the current build is deliberately narrow. I would expect the checker and the power-sharing walkthrough to be the whole experience for now, with the rest arriving later.

Since the app is free, there is little risk in trying it to see whether your hardware cooperates. The trade-off is that anything beyond the two headline jobs is a promise rather than a feature you can use today.

What you need before the first transfer

The setup described is physical rather than digital. You place your phone on the rear face of another smartphone to start the charging process, so both handsets need to be in hand and positioned correctly.

The one requirement that matters is hardware support, and that is exactly what the compatibility check exists to confirm. A phone without wireless charging capability cannot receive power this way, no matter how the app is configured. The developer's steps assume two devices that can talk to each other across their back panels.

The app came out in November 2023 and was last updated in August 2026. For a utility this small, that is not unusual.

A modest tool for phones that already share power

This fits people whose handsets support wireless power sharing and who want a straightforward way to check compatibility and start a transfer. It also suits anyone curious about whether a phone in the household can charge without a cable, since the checker answers that in a minute.

It is less compelling if you already know your hardware and your phone's own settings handle reverse charging without help. The app is free and carries no in-app purchases, so the cost of trying it is your time and some screen space. For a 3.8 average across thousands of ratings, that seems like a fair trade for a narrow utility.

My recommendation is to install it when you need the compatibility answer or the back-to-back charging steps, and to keep expectations modest. It does two jobs, it does them for free, and the developer has said more is coming. That is a reasonable place for a demo-category app to sit.
