Frequently Asked Questions
How long does it take to charge?
About 4–6 hours. Watch for the LED to turn solid green.
Can I use a fast charger?
Use a standard 5V USB adapter. Higher wattage won’t help and can add unnecessary heat.
Will it work while charging?
Yes, but letting it charge uninterrupted is better for battery health.
What if the LED never turns on?
Try another cable/adapter, reseat connections, and inspect the port. If it persists, the battery or cable may need replacement.
