Quick summary

Always use the correct Razor charger for your exact model (wrong charger = poor charging or damage).
Charge indoors, dry, and supervised — keep the scooter and charger well-ventilated.
Don’t “run it completely dead” every time. Topping up after rides is usually better for everyday use.
If it won’t charge: check the wall socket, then the charger LED, then the charge port fit/condition.

Before you plug anything in (30 seconds that prevents most problems)

Let it cool down first: if it’s just been ridden hard, leave it 15–30 minutes.
Dry only: never charge a scooter that’s damp. Wipe down and let it air out.
Use a safe charging spot: hard floor, away from soft furnishings, curtains, or clutter.
Check the charge port: make sure it’s clean and the plug fits snugly (no forcing).

Step-by-step: the safest way to charge

Turn the scooter OFF (if your model has a power switch).
Plug the charger into the scooter first (firm, correct orientation).
Then plug the charger into the wall socket.
Check the charger light (most chargers show one colour while charging and switch when full).
Let it charge fully for a proper first charge and for best day-to-day reliability.
Unplug from the wall first, then unplug from the scooter.
Refit the charge port cover (if your model has one) to keep dust out.
Store it indoors at normal room temperature if possible.

Small habit that helps battery life

If it’s not being used for a while, avoid leaving it fully flat. A short top-up every few weeks (or per the manual) is usually better than forgetting it for months.

Common charging questions (and what usually fixes it)

1) “The charger light is green straight away”

Try a different wall socket (sounds basic — it’s genuinely common).
Reseat the plug at the scooter charge port (firm, no forcing).
Check the charge port for dust/debris and confirm the charger is the correct one for the model.

2) “The charger light never changes”

Give it more time for a full charge (many kids scooters take several hours).
Make sure the scooter is OFF while charging.
If the charger or cables feel unusually hot, stop charging and inspect for damage.

3) “It charges, but the ride time is suddenly much shorter”

Cold weather reduces battery performance — indoor charging/storage helps.
Check tyre pressure (soft tyres can feel like a weak battery).
Heavier riders, hills, and stop-start riding will reduce run time.

4) “It won’t charge at all”

Confirm the socket works (plug in something else).
Inspect the charger plug and cable for kinks/cuts.
Check the scooter’s charge port is not loose or damaged.
If you need help, start with the exact model you have so support can match the right charger/spec.
