The various embodiments herein disclose a charging adapter to enhance a battery backup capacity of a load device. The charging adapter comprises an adapter circuit, and a supplementary power supply unit. The adapter circuit comprises a voltage translator and a current converter. The supplementary power supply unit comprises a processor, a secondary power source, a charger display, a Global Subscriber Module (GSM) and a GSM activation switch. The secondary power source charges simultaneously during a charging cycle of the load device. The secondary power source act as a primary power source when the main power supply is switched off. The secondary power source supplies the stored power to the load device when a voltage of the load device is lower than the voltage of the secondary power source. |
