Power banks have huge market potential, with the current market at $12.88 billion and a CAGR of 11.89%. The reason is that they allow you to use your mobile even as it charges. You can charge these devices once and use them multiple times to charge mobile phones, tablets, and any other USB chargeable device.
The batteries are lithium-ion and lithium-polymer, which can store high voltage per unit mass and volume. Moreover, they are very portable and can fit into any backpack and even handbags.
Ever wondered what pass through charging is? It is a technology that allows you to charge another gadget while it charges itself. This technology will enable you to stay connected even when your phone and power bank have no battery charge left.
You can plug the pass through power bank device into a power outlet and connect your phone to the device. It allows both devices to charge simultaneously, saving your precious time.

A series of power regulating circuits are enclosed in a pass through device. This technology sends power from the wall socket to the power bank connected to it. The power then passes through the power bank to the device connected to it. This way, both the power bank and the device are charged simultaneously.
This ensures that the connected device is charged at regular speed and the pass through device is charged at average or less than normal speed.
You may wonder, when there is a wall socket, why not charge the phone directly? The answer to that is the wall outlet can connect to only one adapter, while a pass through charging device will allow you to connect multiple devices using USB cables.
Choose the Right Power
Power banks range from 2000 milliamp-hours (mAh) to even 15000 mAh. The more the mAh, the higher the power and the more recharges for your phone. For example, a 5000 mAh battery will allow you to charge an iPhone 7 a little over once, while a 10000 mAh charges the same phone thrice, and a 15000 mAh battery will charge the device five times. You can charge kindle readers, Bluetooth speakers, headsets, and just about any gadget with a pass through charging power bank.
Wall Power Output
When charging a single device, 5 watts (1amp) or 12 watts (2.4 amp) is enough. But when you are charging multiple devices, you need at least 24 watts of energy for optimal charging.
Input and Output Cables
The device will need one input cable, usually a micro USB connected to a wall charger that charges the power bank, and two output cables that charge other devices. The gadget will have four or five small dots that flash sequentially as the device charges. When all the dots are lit up, the device is fully charged, and when only one is flashing, you need to plug it in.
Pass through charging is another win in the field of smart inventions that keep you on the go. It allows you to charge your power bank and smartphone (or another device) simultaneously, saving you a lot of time. This article should answer your questions on how the tech works.
