How long do Kado Bars need to charge? There is no single answer, because charging time depends on the specific model, its battery size and the charger you use. The safest approach is to follow the instructions on the packaging or the manufacturer’s page, watch the indicator light, and unplug the device as soon as it is full. This guide is for adults only and focuses on general battery safety.
Key takeaways
- Charging time depends on the model; check the packaging, leaflet or official product page first.
- Use a suitable USB cable and a low-power, reputable source, and never leave the device charging unattended or overnight.
- Stop using any device that is swollen, hot, leaking or damaged.
- In the UK, single-use vapes can no longer be sold, so recycle old devices through proper channels.
How long do Kado Bars need to charge?
Small vape batteries usually charge much faster than a phone, often within a short time rather than many hours, but the real figure depends on the device. Because manufacturers use different battery capacities and charging circuits, any number you see on a forum is only a rough guess. The reliable sources are, in order:
- The printed instructions on the box or leaflet.
- The official product page for your exact model.
- The retailer or manufacturer’s customer service.
- The indicator light on the device itself.
If none of these give a clear answer, treat the indicator light as your guide, and do not guess by leaving it plugged in for hours.
Check what type of device you actually have
Not every vape-style product is rechargeable. Some are sold as single-use and have no charging port at all, while others have a built-in battery and a USB-C or micro-USB port. Look closely at the base or side of the device.
| What you see | What it usually means | What to do |
|---|---|---|
| A visible USB-C or micro-USB port | The battery is designed to be recharged | Follow the model’s charging instructions |
| No port at all | Not designed to be recharged | Do not try to open or force-charge it |
| Light flashes when plugged in | Charging is in progress, though patterns differ | Check the manual for what each pattern means |
| Light turns off or changes colour | Often indicates full charge on many devices | Unplug the cable |
General safe charging steps
- Use the cable and port type recommended for the device, typically a standard USB cable in good condition.
- Plug into a reputable low-power USB source, such as a laptop USB port or a certified wall adapter.
- Watch the indicator light for the first few minutes to confirm it behaves as expected.
- Unplug once the light shows the device is full.
- Charge on a hard, non-flammable surface away from bedding, curtains, sofas and clutter.
- Let the device cool to room temperature before using or storing it.
Why overcharging and bad chargers are a risk
Most vape devices use lithium-ion batteries, the same family of batteries found in phones and laptops. These batteries are very safe when used as designed, but they can overheat if they are damaged, charged with the wrong equipment or left unattended. You can read more about the technology in the Lithium-ion battery article on Wikipedia.
Things you should not do
- Do not charge overnight or leave the device unattended.
- Do not use damaged cables, high-output fast chargers of unknown quality or cheap unbranded adapters.
- Do not charge a device in a pocket, bag or hot car.
- Do not puncture, crush, open or burn a device or its battery.
- Do not keep using a device that is swollen, very hot, leaking or smells unusual.
Troubleshooting charging problems
| Problem | Possible cause | What to try |
|---|---|---|
| Light does not come on | Faulty cable, dirty port or flat battery that needs a few minutes | Try a different known-good cable and clean the port gently with a dry, non-metal tool |
| Light flashes but device will not work | Battery protection or empty liquid | Check the manual; contact the seller |
| Device gets hot while charging | Damaged battery or unsuitable charger | Unplug at once, move to a safe hard surface and stop using it |
| Battery drains very fast | Ageing battery or heavy use | Replace the product rather than trying repairs |
If a device is hot, swollen or smoking, unplug it only if it is safe to do so, move away and call the emergency services if there is a fire. Never try to put out a lithium-ion fire with a small amount of water or by yourself if it is spreading.
Storing and disposing of devices responsibly
Store devices at normal room temperature, out of direct sunlight and away from children and pets. Batteries and electronics should never go in household rubbish or normal recycling bins. In the UK, the sale of single-use vapes has been banned since 1 June 2025, and retailers and council recycling centres have collection points for electrical waste. Check your local council website for the nearest drop-off.
Adults only, and getting support
Vapes contain nicotine in most cases, which is addictive, and they should only be used by adults who already smoke or vape. It is illegal to sell them to anyone under 18 in the UK. If you want to cut down or stop, the NHS website has free quit support, and a local pharmacy can advise on stop-smoking aids.

Frequently asked questions
Can I charge a Kado Bar overnight?
No. Leaving any lithium-ion device charging unattended or overnight increases risk. Charge it while you are awake and nearby, then unplug it when full.
What cable should I use?
Use the cable type that matches the port on your device, usually USB-C or micro-USB, and make sure it is undamaged. A reputable cable from a known brand is a safer choice than an unbranded one.
What does the light mean when charging?
Light patterns differ between models. Many devices show a steady or flashing light while charging and change colour or turn off when full, but check your packaging for your exact model.
Is it safe to use a phone fast charger?
It is better to use a low-power USB source. Many small devices are designed for modest charging currents, and a quality charger will usually negotiate safe levels, but a low-power port avoids unnecessary risk.
What should I do with a dead device?
Do not throw it in normal bins. Take it to a retailer collection point or your council’s electrical recycling facility so the battery is handled safely.
Conclusion
How long Kado Bars need to charge depends on the model, so rely on the manufacturer’s instructions and the indicator light rather than a fixed number. Use a good cable and a low-power source, charge on a hard surface while you are present, and unplug when full. If anything looks or feels wrong, stop using the device and dispose of it through proper electrical recycling.
