Key Takeaways
A device that will not fire is usually a power or contact problem rather than a broken one. Work through the cable, the contacts and the activation method before concluding anything is wrong.
Start with the cable and the power source, then clean the charging contacts, then check how the device is meant to activate. Most no-fire complaints resolve at one of those three steps.
Is It the Cable or the Device?
Test the cable on something else first, because a failed cable looks exactly like a failed device.
Charging cables fail far more often than the devices they serve, and they fail invisibly. Swapping in a cable you know works takes a moment and rules out the most common culprit.
The power source matters too. Some low-output ports do not deliver enough to charge a small device reliably, so it is worth trying a different one.
Could It Be the Contacts?
Often, yes. Lint, dust and residue collect on the charging contacts and interrupt the connection.
A device carried loose in a pocket picks up debris quickly, and the contacts are exactly where it settles. A dry wipe across them is often the entire fix.
Keep liquids away from this area. Moisture around contacts causes more faults than it clears, which is why a dry cloth is the right tool.
How Is the Device Meant to Activate?
Some fire when you draw on them, others need a button, and a few need several rapid presses to wake up.
This catches people out constantly, particularly when switching between devices. The table below covers the usual suspects in the order worth trying them.
| Symptom | Most likely cause | What to try |
|---|---|---|
| No light when charging | Cable or power source | Swap the cable, change the port |
| Charges intermittently | Dirty contacts | Dry wipe across the contacts |
| Light on, no vapour | Activation method | Check whether a button is needed |
| Fires briefly then stops | Protection cut-out | Take shorter draws |
| Nothing at all, ever | End of life or a fault | Contact the retailer |
What If It Fires but Stops Part Way Through a Draw?
That is usually a built-in cut-out doing its job rather than a fault.
Many devices limit how long they will fire in one go, as a protection measure. Long draws hit that limit and stop, which feels like a failure but is not one.
Shorter draws usually solve it, and they tend to taste better anyway. Our guide on vaping technique covers this in more detail.
When Is It Genuinely Faulty?
When a known-good cable, clean contacts and the correct activation method still produce nothing at all.
If you have worked through those and the device is still dead, it is either at the end of its life or genuinely faulty. Either way, further troubleshooting will not help.
A device that fails early should be raised with whoever sold it. Contact our team about anything from the disposables range, all third-party lab-tested by Pure Standard Extracts.

Frequently Asked Questions
Why is there no light when I plug my vape in?
Most often the cable or the power source. Test the cable on another device before assuming the vape has failed.
How do I clean the charging contacts?
A dry wipe across them. Keep liquids away from that area, since moisture near contacts causes more faults than it fixes.
My vape lights up but produces nothing. Why?
Check how it is meant to activate. Some fire on the draw, others need a button, and a few need several rapid presses.
Why does it cut out mid-draw?
Many devices limit how long they will fire in one go as a protection measure. Shorter draws usually solve it.
Can a dead battery be revived?
If the cable and contacts are fine and it still will not take charge, there is no reliable way to bring it back.
Does cold weather stop a vape firing?
Cold thickens the extract and can reduce battery performance, so a chilled device often improves once it warms to room temperature.
Should I try a different charger?
Yes, that is worth doing early. Low-output ports sometimes fail to deliver enough for a small device.
When should I contact the retailer?
When a known-good cable, clean contacts and the correct activation method still produce nothing, particularly if the device is new.
