If the charger's output voltage is less than the gadget being charged, it won't function.

For instance, if your gadget has a 1,500mAh battery, it is advisable to go for a Battery Bank with twice or thrice power (i.e., 3,000mAh or above).


Another crucial aspect of a Battery Bank is its built quality. The Battery Bank's overall characteristic not only infers its performance but also how promptly and accurately the energy-transfer from it to the gadget being charged.

Are Battery Banks Bad for Your Phone?

Owing to the extensive usage of mobile phones these days, it is incredibly significant to keep batteries charged most of the time. Most cell phone users charge their phones multiple times a day to avoid interpretations due to battery discharge. However, it is not always possible to carry a charger, and here's where a battery bank comes to use. Today almost every smartphone user carries a portable power bank – the Battery Bank.

How Does A Battery Bank Work?

A Battery Bank is merely an energy storehouse like a battery. It has input and output ports. The input port enables the charger's connection, while the output is where the gadgets obtain the Battery Bank connection. In the case of a portable Battery Bank, the input and output connectors are USB compatible. Battery Bank stores power when it is charged. This power will be used as the power source to the gadget that uses the Battery Bank.

Portable Battery Banks is a specific battery in a particular case with a special circuit to regulate energy flow. They enable you to store electrical energy (deposit it in the bank) and then later utilize it to charge up a mobile gadget or any other gadget (withdraw it from the bank)

●Circuit Block Diagram

A Battery Bank has an input port, charging circuit, battery, discharging circuit, an output port, and pointers.

The input port is utilized to charge the Battery Bank. The charging circuit is formulated to recharge the Battery Bank from a charger. It controls the voltage and current that will supply to the battery. The battery is the energy storage facet. The discharging circuit is working almost the same as the charging circuit.
