Needs improvement

I confess I have had some issues with this app, such as not being able to use it to start charging sessions and some issues with logging in. It should have a support line 24/7 taking into consideration the nature of the service they provide however there’s not even a phone number available. They answer emails in business hours in an efficient and relatable manner.

Hello João. Thank you for your feedback, we really appreciate it 🙏 We understand how important reliability is when planning your trips. While the app is designed to allow remote activation, some charging stations may still require a physical card depending on the operator.

Ripoff

I've been using this app for two months. While the service is quick and reliable, the pricing is completely unreasonable. I recently switched to a local app; at the exact same charging station, I now pay €0.14 per kWh, whereas Miio was trying to charge me €3.98. This price difference is unacceptable.

Fiddly

There’s always some issue with this app, and the ‘auto’ topup never works. The app never locates the charger I’m standing RIGHT next to, and there are no clues about which charger is which. I don’t know how apps can still be this bad - surely just run the customer feedback through Claude code?!?

Response from developer

Hello! Thank you for your feedback. We’re sorry to hear you’ve had trouble using the app, especially with auto top-up and finding the right charger. We understand how frustrating that can be when you just want to start charging. We’ll take your feedback into account as we keep improving the app. If you’d like to share more details, please contact us at support@miio.pt. See you soon!

No refund from wallet

They dont offer a way to get money back from the wallet, if you dont want to use miio any more. That seems on purpose. I asked the customer support, they went silent, no response

Response from developer

Hi! First of all, thank you for your feedback. We’re sorry to hear that your experience wasn’t perfect. Regarding wallet top-ups, please note that, according to miio’s Terms and Conditions, wallet balances are intended to be used for charging sessions and are not refundable. That said, we’re sorry if you didn’t receive a timely response from our support team. If you still need assistance or clarification, please send us an email at support@miio.pt, and we’ll be happy to help. See you soon!

It works

Out of the 7 different apps I’ve tried In Portugal to charge a car this is the one that actually only worked without a physical card. They do charge a premium but worth it if you’re in a bind.

That’s it

An ordeal to use this app

Both times I have use Miio it has been a nightmare. Instructions and usability are incredibly bad.
We couldn’t connect to the fast charger because it didn’t work so had to go to slow charger.
I was with two of my very tech savvy sons but they were also finding it very difficult to use.
On the last charger it didn’t even make it clear which port related to which reference number

This is a real obstacle to renting electric cars in Portugal

The app doesn’t work

This is the least bad of all the apps available in Portugal for EV charging. The app allows you to find a charging station but don’t bet your travels on it unless you have a physical card to activate the station. I use ViaVerde as a backup, which at least lets you activate the station without a physical token.

Top Charger

Perfect charger, excellent restaurant, breathtaking view

Response from developer

Hello, Thank you for your kind feedback!

Almost tripple the price of the local provider in Portugal

Hello, I have used the App for a Hotel charger in Lagos Portugal. The Hotel Charger expect only local bank cards so I followed ChatGPTs proposal. In the end miio charged instead of the local price on 25€cents almost the tripple price of 70€cents. Probably I feel liked hundreds other miio customer. There should be more one star ratings.

Response from developer

Hello Frank. We’re truly sorry to hear that the price you paid at the hotel charger wasn’t what you expected. To clarify, the final price of a public charging session is determined by several components set by different entities: the energy supplier (miio), the charging point operator (CPO), the Network Access Tariff, and the IEC contribution. These values can vary significantly depending on the CPO and the type of station you use. In some locations, the CPO charges per minute instead of per kWh, which can lead to higher costs, especially if the vehicle stays connected after the charge is completed. Because pricing may differ from station to station, we always recommend using the price simulation feature in the miio app before starting a session. This helps ensure full transparency and allows you to choose the most economical option available. If you’d like, our support team is always available to review your session in detail and assist further. You can contact us at support@miio.com.

muito chato

Muito chato de usar, extremamente complicado. E burocrático. E pretendendo vigiar todos os seus passos. Um inferno.

Overcharging v advertised price

Advertisers as 18cents charged me 61cents per KWH. Also stopped my active session when i topped up (still had 8 euro left), so had to go back to car plug out cable , plug in and restart another session. So frustrating.

Response from developer

Hello. Thank you for your feedback. To give you some context, public charging prices include several components: energy (miio), Network Access Tariff (TAR), CPO fees and the IEC contribution. These vary depending on the station, operator, pricing model (per kWh or per minute) and charger type. Some CPOs charge per minute, so costs continue if the car stays plugged in after charging. We recommend checking the Prices section and using Simulate in the app to estimate your session cost before starting. User comments can also help you choose the best station. Public charging is naturally more expensive than home charging due to infrastructure and service costs, but we work to offer competitive and transparent options while maintaining a high-quality app and experience. If you feel that you have been charged unfairly, please contact us at support@miio.com, and we will be happy to help you! See you soon!

Avoid if you can

I’ve been using miio for a while now, and unfortunately the experience has been incredibly frustrating. After trying several charging stations—none of which worked through the app—I finally found one that did, but only after a couple of weeks. When I eventually managed to charge, the cable wouldn’t disconnect, and customer support offered no real help.

A few weeks later, I happened to pass by the same charger and saw my cable lying on the side of the road. It seems someone had disconnected it without telling me, and I received no communication or explanation from miio.

To try to avoid issues with the app, I ordered a fob. It never arrived—twice. Now I’m being told it will take 21 days from my original payment date, which is far from acceptable.

Overall, everything with miio feels like unnecessarily hard work. From unreliable chargers to poor communication and extremely slow service, the entire experience has been disappointing. Not recommended

Some situations depend on the charging operator, but our support should always guide you better. We’d like to review your case and resolve the pending issues . If you can, please contact us at support@miio.com with your account email. See you soon!

Useless

What kind of fools developed this app? It forces me to give a phone number as part of the signup process, but as soon as I try and enter my phone number the submit button disappears so I can't submit my phone number. Using an iPhone 15. Standing on the side of the road trying to get a charge for my car. Thanks for nothing

Defaults to 200 Euros when I clearly selected 20 Euros

The default reload is 20 euros, but it automatically charged me 200 Euros, what a scam?!

Response from developer

Hello, We are sorry to hear that you have been charged more than expected. In order to help you with this, please contact us at support@miio.com, and we will be happy to help you solve this situation.

Avoid

Don’t recommend. The app takes non refundable deposit and while not used just disappear in their system.

Didn‘t work

When I enter my email address and telephone number in the app under Settings, I can no longer return to the app itself.

It works fine but you need the card.

When I try to use only the app, it usually doesn’t work, but the card works perfectly. The problem is that if you don’t live in the country or don’t own an EV, you can’t get the card. Miio should solve this by making the card available locally — in stores, supermarkets, and even at rental agencies.

Will not respond to emails

I used the app for a short holiday where I had to charge an EV. At the end I emailed them twice requesting them to refund my balance but never heard back from them. Extremely poor service.
