Most devices have an indicator to show that your battery level is low. Naturally, this varies from brand to brand, but here are a few general guidelines:
- If your device has a coloured LED this will turn red when your battery level is running low (typically 30% capacity or less).
- If your device has a single-colour LED this will typically flash several times to alert you that you're low on charge.
- If your device has a display screen, it will have a small battery icon showing your current level.
Most devices will have a lower output when they are running low on battery. This means you may find the flavour or amount of vapour is thinner or not as strong. This tends to be a good indicator your device needs a quick charge. This does not apply to devices with a 'fixed wattage' feature.
