A power bank is used as a portable charger that replenishes your electronic gadgets. Not only because of its portability, but a power bank is one advisable device to have for emergency preparedness.
It’s a must-have in your survival kit in case of a power outage. In fact, this isn’t just an essential device for busy working people, but also for preppers. For this reason, carrying a power bank around for use as a portable charger is usually necessary in all circumstances.
However, having the right power bank is essential. So, let’s find out how a power bank works and how to choose the right one.
Cable Charging vs Power Bank
Cable Charging:
- Charges devices directly from a wall outlet or USB port using a charging cable.
- Typically provides faster charging speeds compared to power banks.
- Convenient when an electrical outlet is available.
- Requires bringing the charging cable with you.
- Device must be near the power source during charging.
Power Banks:
- Portable battery packs that can be charged and then used to charge other devices on-the-go.
- Provide flexibility to charge devices without needing access to a wall outlet.
- Can charge multiple devices in succession before needing to be recharged.
- Typically provide slower charging speeds compared to cable charging.
- Need to remember to keep the power bank charged.
- Additional device to carry around.
The best option depends on your specific needs and usage scenario. Cable charging is best when you have reliable access to power outlets, while power banks are more convenient for charging on-the-go without access to wall outlets. Many people use a combination of both methods for maximum flexibility.
How Power Banks Work
The main parts of a power bank usually consist of:
- Battery (lithium-ion or lithium-polymer). These are the power bank’s most important parts. Batteries made of lithium-ion or lithium-polymer are frequently utilized because of their high energy density and lightweight nature.
- Charging circuit. A charger circuit receives power from a power source. Its main job is to charge and discharge the power bank.
- Output ports (USB). USB ports allow you to connect your gadgets to the power bank so they can be charged. One or more USB ports on the power bank may be available to support several devices at once.
Charging and Discharging Process
Three steps make up the process: storing, releasing, and absorbing energy. A power bank’s internal battery stores energy in chemical form after being charged by an external power source, like a wall outlet.
The battery uses the output port to transfer electrical energy to the linked device when needed. Meanwhile, if your device is already full you can just disconnect it from the power bank’s port, and the power bank’s battery itself will discharge the supply on your device.
Choosing the Right Power Bank
Here are what you need to think about when choosing a power bank:
Capacity (mAh)
Though you would usually choose a power bank’s mAh depending on your needs the common capacity is at least 5,000mAh. And as always, of course, larger capacity like 20,000mAh-40,000mAh has its best advantage.
Output ports and Power Delivery (PD)
This is really essential. The charging speed of a power bank is dependent on its type of port. Additionally, multi-port chargers and power banks can be used to charge your laptop.
Size and Weight
Portability is a big deal. A power bank that is slim and small yet powerful is really a nice choice. A portable power bank won’t be a hassle for travel.
Additional Features
A wireless and fast-charging power bank really changes the game. If you’re a prepper or a person with a fast lifestyle, a wireless and fast-charging power bank is really a factor to look into.
