Portable Walnut Wood Power Bank with 2000mAh 18650 Battery and 95% Conversion Rate

This portable power bank offers a practical solution for keeping your devices charged while away from a mains socket. Unlike ordinary plastic alternatives, it features a solid walnut wood shell that provides a natural grip and a distinctive look. The internal 18650 liquid lithium ion battery delivers a capacity of 2000mAh, enough to give a typical smartphone a partial or full top-up depending on its battery size. With a conversion rate of 95%, more of the stored energy reaches your device rather than being lost as heat. The unit supports smart charging and discharging, which helps protect connected devices from overcharging or excessive discharge.

Features and Construction

This power bank is built around a cylindrical 18650 battery housed in a walnut wood shell. The design is compact and lightweight, making it easy to slip into a pocket or bag.

Material and Build

The outer shell is made from walnut wood, giving the power bank a solid, natural feel that differs from plastic or metal casings. The battery is a liquid lithium ion type (18650) with a cylindrical aluminium shell inside. The entire unit measures 100mm by 25mm by 25mm, and weighs 190g including its gift box packaging.

Size and Practical Fit

At just 100mm long and 25mm thick, this power bank fits easily into a small pocket, handbag, or pencil case. The slim cylindrical shape is comfortable to hold and does not add significant bulk to your daily carry.

Everyday Home Use
