Power Banks have become one of the most important mobile phone accessories nowadays. Big screen smartphones, tablet PCs, notebook computers, digital cameras and other electronic are equipped to do diverse functions, leading to more frequent use, especially for business users and people who travel frequently.
Power Banks are critical to extending usage.
There are hundreds of power banks you can find online, but we are here to help you to choose the best one for your needs.
What you need to know about Power Bank capacity.
Power Bank capacity refers to how long the power bank battery can charge the gadget.
It is measured in mAh or milliamps for an hour. When a power bank is charging a phone, some of the charge is lost in the transfer of power. In simple terms, it takes energy to transfer energy. So, the real capacity is about 60% of the battery capacity listed on the Power Bank which has a high quality battery.
For cheaper Power Banks with inferior batteries, the real capacity is lower because the battery does not work efficiently.
Our Power Bank Recommendations
Sony CP-E3 3000mAH
Coolnut CMPBSUN-25 5200mAh

Between Lithium18650 and Polymer Li-ion batteries, always choose Polymer Li-ion batteries.
- They are lighter than Lithium18650,
- Not prone to explosion,
- More charging capacity than the average brand 18650,
- Discharge characteristics are better, stable and have higher discharge platform as they use gel electrolyte rather than a liquid electrolyte
- More safety and guarantee
- Lithium18650 is of more weight, more heat produced.
Look at the conversion rate.
The level of mobile power conversion rate is one of the core measures. The amount of energy that can be converted into charging is them conversion rate which counts on the circuit board efficiency and the capacity of the battery.
Based on rated specification of the gadget’s battery, the number of “full charges” for that particular gadget can be determined. The more the conversion ratio and/or the capacity of the battery the more will be full charge cycles.
Try & assess the quality of the materials.
Check the Power bank internal structure to check whether the key parts are imported or domestic made ex: Boosting systems, Capacitors etc.
Check the product charge management system.
Power banks have an in-built charge management system. It adjusts the charging current according to the voltage of the Lithium namely pre-charge, constant voltage charging and floating charge.
Today Power banks mostly are of ordinary linear charge management, which is an old technology. It takes more than 15-20 hours for high-capacity rechargeable source to be full.
Smartphones use a pulse charge management which has multiple advantages such as low temperature, long battery life etc.
Check the product’s features.
There are respective features specified such as anti-reverse circuit design which can protect from damage. Dual interface design facilitating multiple electronic products to be used simultaneously is an obvious choice.
Figure out your needs.
For example, if you take a lot of long trips or are on the road a lot, consider buying high-capacity products otherwise a medium-capacity compact product would be your best choice. You can also choose phones with big batteries from our list of upcoming phones in India.
Pay attention on the weight of the product.
Usually, try and go for a power bank that weighs around 600g-700g.
