Compact power bank for phones and small tablets

The LVSUN LS-B300 is a 3800mAh lithium-polymer power bank designed for smartphones and small tablets. Its slim 11mm profile fits easily in a pocket or bag for on-the-go charging. A built-in LED torch adds utility in low-light situations.

Single USB-A port with 5V 2.0A output

The only charging interface is one USB-A port delivering 5 volts at 2.0 amps. Input is limited to 1 amp, so the bank itself recharges slowly. Buyers who need faster recharging, multiple simultaneous ports or higher voltage output should look elsewhere.

Passive cooling with no fan noise

The solid-state design has no moving parts, so it runs silently and produces minimal heat during normal use. The leaf-shaped indicator LEDs show remaining capacity without drawing significant power. No active thermal management is required or present.

Questions about this item

How long will the 3800mAh capacity keep my phone running in daily use?

The 3800mAh lithium-polymer cell typically provides one full charge for most smartphones, depending on the phone's own battery size and usage while charging.

What does the 2.0A USB output mean for charging speed?

The single USB port delivers up to 5V 2.0A, so phones and small tablets charge at their normal wired speed; devices that need more current will still charge but at a slower rate.

Will the 11mm thickness fit in a slim pocket or small bag compartment?

At 11mm thick the power bank slides easily into a jeans pocket, a shirt pocket, or a narrow organiser sleeve without bulging.
