Wireless Reverse Charging

Review by eFreeware

Running out of battery is rarely a dramatic event, but it is almost always inconvenient. You are at a friend's place, at a conference, or at the end of a long day away from a charger, and the percentage on screen is dropping faster than you would like. If someone nearby has a phone with a full battery, the idea of borrowing a little power without hunting for a cable is appealing. That is the scenario Wireless Reverse Charging is built around.

The app comes from Boss Inc and sits in the Libraries & Demo category on Google Play. It is free to download, carries ads, and offers no in-app purchases. It has been installed more than 50,000 times and holds a 3.9 average from 610 ratings. It arrived in August 2025 and was last updated in January 2026.

The pitch is straightforward: use one phone to top up another, with no wires involved, and use the app to check whether the hardware on both ends can actually do it. The developer describes the process as exchanging power between two handsets placed together. What follows is what the app does, what it asks of you, and who I think will get the most from it.

Checking compatibility before you bother

The feature the developer leads with is a compatibility checker. Before you try to pair two phones, the app tells you whether a device supports wireless power sharing, either as the phone giving charge or as the one receiving it. That is a sensible starting point, because reverse wireless charging is not universal, and the hardware has to be present on both sides for anything to happen.

The value here is mostly in avoiding wasted effort. Without a check, you might hold two phones together, wait, and see nothing happen, with no way to tell whether the problem is the hardware, the position, or something else. The app is meant to remove that ambiguity up front, so you know whether a connection is even possible before you start.

I would expect this to be most useful for people who own a phone with power-sharing hardware but have never used it, or who are trying to help someone whose handset they do not know well. It is a small thing, but it turns a vague guess into a clear answer.

The transfer itself and the status readout

Once compatibility is confirmed, the actual sharing step is physical rather than software-driven: you place one phone against the back of the other. The app frames this as a simple back-to-back arrangement, with no cables and no separate accessories. The charging hardware does the work; the app is there to guide you into the right setup.

A status indicator accompanies the process. It shows whether the phone is currently charging or supplying power, which matters more than it might sound. When two devices are pressed together, it is not always obvious which one is draining and which one is filling up, and the indicator gives you that answer in real time.

The interface is simple and user-friendly, with clear instructions and minimal setup. You open it, check, align the phones, and watch the status.

What it asks of you and what it costs

The main requirement is hardware. Both phones need to support wireless power sharing for a transfer to take place, and the compatibility checker exists precisely because that is not something you can assume. If your device does not have the necessary hardware, the app can tell you so, but it cannot add the capability.

The app is free to download and carries ads. It does not offer in-app purchases, so there is no paid tier to consider and nothing to unlock through spending. The trade-off for a free utility of this kind is the advertising, which is worth factoring in if you prefer a completely clean interface.

The app is a checker and a status readout rather than a manager of your files or accounts. The practical cost is your attention: you still have to place the phones correctly and keep them aligned while the transfer runs.

Getting a useful result out of it

The most reliable way to use an app like this is to check first and place second. Run the compatibility test on both handsets before you bring them together, so you know whether to expect anything at all. If one device fails the check, you have saved yourself a minute of holding two phones in an awkward position.

Alignment matters when you do proceed. The app describes placing one phone on the rear face of the other, so a small shift can interrupt the connection. Watch the status indicator; it tells you whether power is moving at all.

It also helps to think about direction before you start. Decide which phone is giving and which is receiving, and keep an eye on the indicator to confirm that is what is happening. If you are lending charge to a friend, this is the difference between helping and accidentally draining your own battery.

The scenario the developer highlights is a familiar one: your battery is low, or a friend's is, and you want to pass some charge across. The app is designed for exactly that moment, not for routine overnight charging or for managing power over long periods.

A narrow tool that does one job

Wireless Reverse Charging is a single-purpose utility. It checks whether your hardware can share power, guides you through placing two phones together, and shows which way the charge is flowing. It does not pretend to be a battery manager or a charging optimizer, and it stays within those bounds.

That narrowness is the point. If you have ever stood with two phones pressed together wondering whether anything was happening, the combination of a compatibility check and a live status indicator addresses a real gap. The 3.9 average from 610 ratings suggests a mixed but generally positive reception.

The ads are the main cost of entry, and the hardware requirement is the main limit. Neither is unusual for a free tool in this category, but both are worth knowing before you install. If your phone lacks power-sharing hardware, the app will confirm that rather than work around it.

For anyone whose device supports wireless power sharing and who wants a clear answer about whether a transfer is possible, this is a focused, low-commitment download. It is not a reason to buy a new phone, and it will not turn a device without the right hardware into one that can share power. Within those bounds, it does the job it sets out to do.
