For most scooter owners, the time it takes to fully charge their electric scooter’s battery is the biggest nuisance. Every serious scooter out there, with a range actually useful for transport and commuting, will take several hours to charge.
Exactly how much time does it take to charge an electric scooters?
Electric Scooter Charging Time
The average electric scooter charging time is 5 and a half hours. Most consumer-grade electric scooters will take between 3 and 8 hours to get fully charged. The scooters with the shortest charging times take less than 1 hour to charge. The scooter with the longest charging time will take more than one full day to charge.
There are a few important factors to consider for knowing the real charge time.
Let’s see exactly how long it will take to charge your scooter to the minute. We will go through the most important principles involved in charging batteries. Also, we will learn how to figure charge times out ourselves.
How to calculate how long it takes to charge an electric scooter
Before we start, you can check out the electric scooter charge time calculator for a simple way to figure out how long you should charge your scooter, although most of the charge times for electric scooters are covered in the table further down in this guide.
In case you are unable to find out the exact charging time for your electric scooter in this guide or anywhere else on the Internet, fear not. Calculating it is very easy.
All you need to know are three things:
- the type of your battery (usually Lithium-Ion a.k.a. Li-Ion, sometimes Sealed Lead Acid, a.k.a. SLA, with other battery types being very rare)
- the energy storage capacity of the battery of your scooter, expressed in Ampere-hours (Ah)
- the output current of your charger, expressed in Amperes (A)
Sometimes these values may be expressed in different units. For example, current may be expressed in mili-Ampere-hours (mAh). In that case, you need to convert them to the units we need. In this concrete example, converting mili-Ampere-hours to Ampere-hours only requires dividing the first value by 1000.
Most batteries of the electric scooters today will be Lithium-Ion (Li-ion), but some older models can have sealed lead-acid (SLA) batteries. Depending on the type, the calculations for the charging time will be different.
The difference occurs because of the different charging efficiencies that these two types of batteries have. Li-ion batteries have a charging efficiency between 80% and 90%, and typically that number is actually 90% (source). On the other hand, SLA batteries have anywhere between 50% and 95% charging efficiency, usually considered to be 70% (source).
The charging efficiency comes into play when calculating the charging time.
Once you have all the data needed, we are ready to do a very simple calculation. The formula for calculating the charging time of your electric scooter is the following:
Charging time (h) = Battery energy capacity (Ah) / [Charger current (A) * Charging efficiency (%)]The formula for calculating the charging time for your electric scooter
Let’s take the famous Xiaomi M365 Pro as an example, and plug its values into the formula. It has a Lithium-Ion battery with an energy storage capacity of 13 Ampere-hours. Its charger has an output current of 1.7 Amperes.
The time it would take to charge it should then be:
13 Ah / [1.7 A * 90%] = 8.49.
That is almost exactly the same as the charging time reported by the manufacturers, myself, and many users worldwide, which is 8.5 hours.
So, while the charging time of the scooter is a widely available specification, it can still be wise to check this for yourself and make sure you are getting the real deal.
Electric scooter charging times
In order to learn everything we can about charging times, let’s take a look into the data available and see what’s going on. The charging times reported are when using the regular chargers of the scooters (some scooters also have fast chargers), and not using the fast charging mode when available. Charging your scooter that way is usually optimal for longer battery life, and it is considered the default.

Electric scooter charging times are sometimes specified in the user manual. Often, they are specified on the websites of the scooter brands or manufacturers.
Also, a lot of the time, this piece of data is available as anecdotal evidence from long-time users that have tested this themselves.
Some models, however, don’t have this information available. For a part of them, the battery energy storage capacity and the current of the charger were available. Therefore, I was able to calculate the charging time by using the formula above.
For a small minority of electric scooters, neither of these data points were available, so they were omitted from the list.
When there were many data points available from multiple sources, I always went with the data reported from users. That most likely to be closest to the truth. The manufacturer data was the second preferred method, and calculating it was the last resort.
Which electric scooter charges the fastest?
As we can see, this title goes to several models of the Micro brand. Four of their electric scooters share the title. They all go from zero to fully charged in one hour, as per the company’s claims. These scooters are the four at the very top of the list:
- Micro e Micro one
- Micro Eagle X3
- Micro Falcon X3
- Micro Peugeot Kick x2
Which electric scooter charges the slowest?
The Dualtron X takes 25 hours to get fully charged!
Still, that charging time is well justified, as the Dualtron X is clearly an elite level scooter. It is one of the electric scooters with the longest range, one of the fastest scooters ever, and one of the best hill-climbing scooters too.
In my opinion, the Dualtron X might be the best electric scooter money can buy. If you wish to check it out, see my complete review of the Dualtron X2, which is the latest version of this scooter.
What is the average charging time for electric scooters?
Finally, we can provide a true, data-driven answer to this question.
The average of the charging times from the list above is 6 hours and 40 minutes. That list contains every possible electric scooter that offers a way to find out its charging time, so this is the true average.
That answer, however, is a little naive and skewed. That average gets largely inflated by the most powerful and most expensive electric scooters out there. They are the most rarely used scooters as well.
If we look for the average among a sample of the most popular, widely used electric scooters, like the following models:
- Xiaomi M365
- Xiaomi M365 Pro
- Ninebot ES1
- Ninebot ES2
- GoTrax GXL Commuter / GoTrax GXL V2 Commuter
- Swagtron Swagger
- Razor EPrime
- Glion Dolly
- Mercane Widewheel
- Zero 9
- NanRobot D4+
- NanRobot D5+
We can clearly see that the average would be much smaller, at 5 hours and 37 minutes. This is a clearly data-driven approach that looks at 12 massively popular scooters. It gives you a very good idea about how fast you can expect your average scooter to charge.
For the vast majority of electric scooter owners, that will be the actual average.
The charge time for more than half of the electric scooters is less than 6 hours. We can safely say that most of the budget or medium-priced scooters will take between 3 and 8 hours to get fully charged.
Can I decrease my electric scooter charging time?
There is one effective way to speed up the charging of your scooter. That is to use a faster charger with a higher current. When you get a charger with more Amperes of current, you will, in effect, cut the charging time by the same factor you increase your current. We can see that from the formula we examined above.
If you are considering this option, only go for it if the scooter’s manufacturer provides a faster charger. Only look at chargers for that specific scooter.
In theory, you could use another charger with a higher current level. However, that might be inviting some trouble, as the charger may not fit the battery perfectly.
The best practice is to only use chargers meant to be used with your scooter and nothing else.
In any case, make sure that the input voltage of the battery is the same as the output voltage of the charger. Otherwise, you risk damaging your battery.
Also, you should be aware that this option can come with a tradeoff. If your scooter doesn’t fully support a faster charger, your battery life will be shortened. You will have to replace your battery a lot sooner than you otherwise would.
Some scooters come with the option to double-charge them, or to plug in two chargers at the same time. This will also speed up the charging, although scooters with this feature are not common. Usually, only powerful scooters with big battery capacities have this option.
Factors that affect charging time
As we already mentioned, the most important factors when it comes to charging time are:
- the type of the battery (Li-Ion are more efficient and get charged faster)
- the energy storage capacity of the battery (the bigger the capacity, the slower the charge)
- the output current of the charger (the bigger the current, the faster the charge)
However, those are not the only factors at play.
One important factor will be the overall condition and degradation level of the battery. Batteries lose their performances over time, and after a while, they become so weak, they are almost useless. Naturally, the older the battery is and closer to its end of life, the longer it will take to get fully charged.
Another factor that impacts the charging time is the temperature of the room where the scooter is charged. The ideal charging temperature for Lithium-Ion batteries is between 10°C and 30°C. The acceptable range is slightly larger, between 5°C and 45°C. As a result, charging in temperatures outside of that range will be slower, and it will also reduce the lifespan of the battery.
How to charge an electric scooter
This is a whole other different big topic, but there are a few key bullet points to always keep in mind so that you get the most out of your battery:
- only use chargers that the manufacturer has created for your specific scooter
- fully charge your battery as often as you can
- avoid leaving your scooter on the charger after the battery is full
- avoid getting your battery completely drained
- charge your scooter in temperatures between 10°C and 30°C, and never in temperatures below 5°C or above 45°C
- don’t plug the charger immediately after riding as the battery is still hot
- don’t ride immediately after charging
