Mobile power bank ni gaw wan n-gun hpe gara hku shinggyin tawn da ai kun?

Mobile power bank ni a madung gaw lithium-ion (sh) lithium polymer battery ni (60% jan manu jahpu a matu jahpan galaw ai). Charge galaw ai shaloi, shinggan na n-gun npawt ( mobile phone charger zawn re ai ni) gaw 5V DC hpe Micro-USB hku nna bang ai shaloi, PCB control board gaw wan n-gun hpe shinggyin tawn na matu chemical n-gun de galai shai kau ya ai:

. Voltage 4.2V du wa ai shaloi, grai n-gun n-jaw na matu, n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-rawng hkra galai shai mat ai.

2. Wan n-gun hpe shinggyin tawn da ai: Lithium ions ni gaw kaja ai electrode (lithium cobalt oxide, etc.) hte n kaja ai electrode (graphe) lapran hta n-gun hpe shinggyin la lu ai. Battery cell langai a nominal voltage gaw 3.7V rai nna, n-gun gaw 5000mAh-20000mAh (data source: IEC 61960 standard) rai nga ai.
