PowerFlex

Review by eFreeware

If your charging happens at a PowerFlex Adaptive Charging Station, this is the app that goes with it. PowerFlex is a free companion tool for electric vehicle drivers who plug in at those stations and want a say in how much energy a session draws, rather than simply accepting whatever the charger decides.

What it offers is a narrow, specific job: you tell the station how much energy you need, and you can watch the session from wherever you are. That focus is the appeal. It is not trying to be a general EV dashboard. It is built around one network of hardware and one task, and it does that task without charging you for the privilege.

The app sits in the Auto & Vehicles category and has been on Google Play since January 2018, with the most recent update landing in September 2026. It has passed 50,000 installs and holds a 4.7 average from 1,139 ratings, with 233 written reviews alongside them. Those numbers suggest a settled, used tool rather than a novelty.

Setting your energy demand before you plug in

The central idea is that you specify your energy demand for the session. In practice that means deciding how much charge you want the station to deliver and entering that figure through the app, so the hardware works to your target instead of a default.

I like the reasoning. Charging needs vary daily, and stating the number yourself puts that decision in your hands.

Its value is tied to that network, not to any charger you happen to pull up to.

Watching a session without standing next to the car

Once charging starts, the app lets you monitor the status remotely. You can check on progress from inside a building, from a waiting room or from home, instead of walking back to the parking lot to peer at a screen.

The remote view is what most drivers would open the app for day to day. It answers whether the car is drawing power and how far along it is, without needing to see the vehicle.

The developer has also fixed a detail that matters for that view: an active session now displays correctly when charging is paused. If a session stalls for any reason, you can still see it in the app rather than wondering whether it vanished.

Changing your mind mid-session

Plans move, and the app accounts for that. You can update your energy demand at any point during a session, so a request made in the morning can be revised in the afternoon without restarting anything.

That flexibility is the feature I find most convincing, because it matches how charging actually gets used. A meeting runs long, a detour appears, or you decide you need more range than you thought, and the target can be adjusted to suit.

Pop-up messages now appear reliably once loading finishes, and a failed refresh no longer hides the list of sessions. These small reliability fixes suggest the developer still tends to the product years after launch.

What it asks of you, and who it fits

The requirement here is straightforward: you need to be charging at a PowerFlex Adaptive Charging Station for any of this to apply. The app is a control layer for that hardware.

If you charge elsewhere, the app offers nothing. It is free, with no ads or in-app purchases, so there is no cost barrier.

It suits drivers who charge regularly at PowerFlex stations and want control over each session's energy. Setting a demand, checking progress remotely and revising it mid-session covers the whole job.

A focused tool for PowerFlex station users

PowerFlex does one thing and does not pretend otherwise. If you charge at PowerFlex Adaptive Charging Stations, it gives you a way to state your energy demand, follow the session remotely and change your mind while charging continues, all without paying anything or sitting through ads.

The 4.7 average from more than a thousand ratings, together with the small reliability fixes in the latest update, points to an app that has earned its users' trust over several years. I would suggest it to drivers on that network who want a say in each session rather than a passive plug-in-and-wait experience.

For everyone else, the app's usefulness depends entirely on the stations you can reach. That is not a flaw so much as the shape of the product: it is a companion for a particular charging setup, and within that boundary it looks like a tidy, dependable choice.

What's new in version 4.5.19

- Your active session now shows correctly when charging is paused. - Pop-up messages show up reliably after the app finishes loading. - The sessions list stays visible if a refresh fails.
