Watch: Student builds power bank for home appliances


Almost everyone has a power bank nowadays to keep our mobile devices running all day long, and allow us to stay productive and connected wherever we are.

But what if you have a power bank that is supersized and can power home appliances? Imagine going on a summer vacation on an off-the-grid camping site or a remote island, and you only have limited or scheduled power supply. This supersized power bank could not only charge your phone through many cycles, but also provide power to your portable appliances.

19-year-old Angelo Casimiro—an Electronics and Communications Engineering student and the person behind the YouTube channel TechBuilder—created a DIY power bank that’s powerful enough to run appliances such as TVs, lamps, and electric fans. The power bank can also be configured for charging via solar panel.

The DIY power bank is made from three USB powerbanks, a DC-to-AC converter, rectifier diodes, two 3-Cell Balanced Lithium Ion Charger modules, wood, contact cement, and tape. It stores enough power to support various home appliances. It can even double the battery life of Angelo’s Lenovo Legion Y520, which is a huge feat since gaming laptops consume so much power.

Together with leading global technology brand Lenovo, Angelo shared the full tutorial on his channel. Watch it below.

The AC outlet power bank is Angelo’s first invention in partnership with Lenovo.
