Electric scooter charger guide: reading the label, fast chargers and safe charging
The charger is the part most riders never think about until it goes missing. Here is how to read its label, when a faster one makes sense, and why only the maker's charger belongs on your battery.

CHARGER
The short answer
No. An electric scooter charger must match your battery, and the safe choice is always the charger the maker supplies or sells for your exact model. The label shows two numbers that matter: the output voltage, which is the battery’s full charge voltage (for example 67.2V for a 60V pack), and the output current in amps, which sets how fast it charges. A maker’s fast charger with more amps can cut the wait sharply. A charger with the wrong voltage, connector or cell settings can damage the battery or start a fire.
Use only the charger the maker supplies or sells for your model. Never a universal or borrowed charger.
The output voltage on the label is the battery’s full charge voltage, a little above its nominal voltage.
More amps means a faster charge, but only a maker’s fast charger knows how hard your battery can be pushed.
Charge where you can watch it, unplug when it is done, and never charge a damaged battery.
How to read a charger label
Turn your charger over and look for the line marked Output. That line tells you almost everything you need.
Output voltage (V). This is the voltage the charger stops at when the battery is full. It sits above the battery’s nominal voltage, because lithium cells are charged to a higher voltage than they average while you ride.
Output current (A). This is how many amps the charger delivers. More amps fill the battery faster.
Input. Most chargers accept 100 to 240 volts AC, which covers a US wall outlet.
Connector. The plug that goes into the scooter. Makers use different shapes and pin layouts, and a plug that fits is not proof the charger is right.
Multiply volts by amps for a rough idea of the charger’s power in watts. Segway, for example, lists a built in 209W fast charger on the Segway Max G3 Plus and about 4 hours to charge its 717Wh battery.
Battery voltage and charger voltage
The number on the scooter and the number on the charger are different on purpose. A scooter is sold by its nominal battery voltage. The charger is labeled with the full charge voltage. Here is how they pair up on scooters in our catalog, from the makers’ listings:
36V battery, 42V charger: E-TWOW lists a 42V 2A charger for the 36V E-TWOW Booster ES, and Gyroor a 42V 2A charger for the 36V Gyroor C1 Pro.
48V battery, 54.6V charger: Kaabo includes a 54.6V 1.75A charger with the 48V Kaabo Urban, and E-TWOW lists a 54.6V 3A charger for the 48V E-TWOW GT SL.
60V battery, 67.2V charger: YUME sells 67.2V chargers for the 60V YUME Raptor2, and Kaabo includes two 67.2V 1.75A chargers with the 60V Kaabo Warrior X Max.
72V battery, 84V charger: Kaabo includes two 84V 1.75A chargers with the 72V Kaabo Wolf King GTR Max.
Never use a charger with a different voltage, even for one charge. A lower voltage charger cannot fill the battery, and a higher one can overcharge it. If you are not sure what your scooter needs, check the manual or the label on the battery, or contact us with your model before you buy anything.
Our guide to electric scooter battery voltage explains why makers choose 36V, 48V, 60V or 72V packs and what the number means for speed and power.
Amps, charging time and fast chargers
For a rough charging time, divide the battery’s amp hours by the charger’s amps, then add some time for the slow final top up. A small amp charger on a big battery takes most of a day. A higher amp charger from the maker can cut that to a few hours. Our guide to electric scooter charging time and cost walks through the math.
YUME shows the effect clearly with three chargers made for the Raptor2 and the Raptor2 13 MPH:
YUME sells matching 5A and 10A chargers for the YUME XTRON and a 2A charger for the X11+. The chargers are sold model by model, which is exactly how you should buy them.
Dual ports are the other route to a faster charge. Kaabo lists about 7.8 hours with the two included chargers on the Warrior X Max, and 2.7 hours with two 5A chargers. YUME lists 7 to 8 hours with dual ports for the Raptor2.
A fast charger is only safe when the maker designed it for your battery. The battery’s cells and management system set how much current it can take. Use a fast charger only if the maker sells or approves it for your model, and if your manual allows it.
Built in chargers
Some scooters carry the charger inside the frame, so you only need a power cord. Segway lists a built in charger on the Segway Max G2 and a built in 209W fast charger on the Max G3 Plus. There is no brick to lose or forget, which suits riders who charge at work as well as at home.
The trade off is that a fault in the charger means a repair to the scooter itself, rather than a new brick. If a built in charger stops working, stop using it and contact the maker or us; see our warranty page for covered faults.
Replacing a lost or broken charger
Buy the replacement from the maker of your scooter, for your exact model. Many listings name the charger in the specs, as Kaabo and E-TWOW do. Before you order, match:
The output voltage, exactly.
The connector shape and pin layout.
An output current your maker approves for your battery.
The model name the maker gives for the charger.
Do not buy a universal charger or borrow one from another scooter. Two chargers can share a plug and a voltage and still be set up differently. A charger that does not match can stress the cells and the battery management system.

Safe charging habits
The US Consumer Product Safety Commission (CPSC) gives clear advice for charging micromobility batteries. In short, CPSC says to:
Charge only with the charger provided or recommended by the manufacturer.
Unplug the device when charging is complete.
Stay present while it charges, and do not charge overnight while you sleep or while you are away from home.
Use replacement batteries only if they are tested and approved for your device and confirmed suitable by its maker.
Avoid batteries that were modified or repaired by unqualified people, or that contain used or repurposed cells.
A few habits from everyday ownership help too. Charge on a hard surface away from anything that burns, and keep the path to your door clear. Let a hot battery cool after a ride before you plug in. Check the charger cable and plug for cuts, bends or scorch marks, and stop using a charger that smells hot or makes noise. If the battery is swollen, leaking, damaged or smells odd, do not charge it. Power off, keep it away from people and send it to a qualified technician.
The output voltage matches your battery’s full charge voltage exactly.
The connector and pin layout match your scooter.
The charger is made or approved by your scooter’s maker for your model.
Any fast charger is one the maker sells or approves, and your manual allows.
The cable, plug and case are undamaged.

Questions riders ask
Can I use a different charger on my electric scooter?
Only if the scooter’s maker supplies or approves it for your model. A charger with the wrong voltage, connector or settings can damage the battery or start a fire, even if the plug fits.
Why does my 60V scooter have a 67.2V charger?
Lithium battery packs are named by their nominal voltage and charged to a higher full voltage. A 60V pack is full at about 67.2V, a 48V pack at about 54.6V and a 36V pack at about 42V.
Do fast chargers damage scooter batteries?
A fast charger the maker designs for your battery works within the limits the cells and battery management system allow. A third party fast charger may not, so use only the maker’s fast charger, and only if your manual allows it.
Should I leave my scooter charging overnight?
No. CPSC advises staying present while a micromobility battery charges, not charging overnight while you sleep, and unplugging when charging is complete.
What should I do if my charger stops working?
Stop using it and check the cable and plug for damage. Replace it with the maker’s charger for your model, or contact us with your model so we can help you find the right one.
