Frequently Asked Questions - Isound-2140 DREAMGEAR

How do I know when the Isound-2140 is fully charged?

The four LED indicators will all be solid when the power bank is fully charged. Each LED represents approximately 25% charge.

Can I charge my tablet with this power bank?

Yes, the 5V/2.1A USB output can charge most tablets, but charging speed may be slower than the original charger. It is compatible with smartphones, Bluetooth headphones, and other USB devices.

How long does it take to charge the power bank itself?

Using the included Micro USB cable and a 5V/1A adapter, charging time is approximately 4 hours. Using a lower current adapter will take longer.

Is it safe to leave the power bank charging overnight?

Yes, the Isound-2140 has overcharge protection, so it will stop charging automatically once full. However, it's always best to unplug it once fully charged to preserve battery health.

Why are the LED lights not turning on?

If the LEDs do not light up when pressing the power button, the battery may be completely discharged. Connect it to a charger for a few minutes, then try again. If still not working, check the cable connection.

Can I use the power bank while it is charging?

Yes, the pass-through charging feature allows you to charge the power bank and simultaneously charge a device connected to the output port. However, this may generate more heat and slightly extend charging time.

What devices are compatible with this power bank?

Any device that charges via USB with a current requirement up to 2.1A is compatible. This includes most smartphones, tablets, Bluetooth speakers, e-readers, and portable gaming consoles.

How do I clean and maintain the power bank?

Wipe the exterior with a dry, soft cloth. Do not use liquids or abrasive cleaners. Avoid exposing the power bank to water, extreme temperatures, or dropping. Charge it at least once every 3 months to maintain battery health.

What does the power bank indicator mean when it blinks?

When charging, blinking LEDs indicate the current battery level: 1 blink = 0-25%, 2 blinks = 25-50%, 3 blinks = 50-75%, 4 blinks = 75-100%. When the device is charging from the power bank, the LEDs show remaining capacity.

Is the DreamGEAR Isound-2140 covered by a warranty?

Yes, DreamGEAR typically offers a 1-year limited warranty against defects. Keep your purchase receipt and contact DreamGEAR customer support for warranty claims.
