Are you tired of waiting forever for your device’s battery to get whole? A fast-charge battery is your answer. Slow charging can be agonizingly painful if you are busy, in a rush, or do not have time to wait for hours.

Fortunately, technology has gradually evolved to develop batteries for fast-charging gadgets. The following article outlines the top 10 fast-charge batteries that will dominate the market this year.

So, let’s get started.

Part 1. Types of fast charge batteries

Knowing the variety of fast-charge batteries is essential for choosing the right one. Each type works best with a particular device and need. The main ones are:

Lithium-ion Batteries

Li-ion batteries are the most common type found on smartphones and laptops. They can store a great amount of energy, charge faster, and are combined with many fast charging systems, such as Qualcomm Quick Charge and USB Power Delivery.

Lithium Polymer Batteries

LiPo is very similar to Li-ion but is thinner and lighter. Its main usage would be in wearables and drones. While it charges fast, it may not last as long as Li-ion batteries.

Solid-State Batteries

The solid-state battery is newer compared to it; it charges faster, is much safer, and is longer-lasting. It uses a solid material instead of liquid, making it more energy-efficient and safer. However, it is not yet commercially available since it is still developing.

Nickel-Metal Hydride Batteries

The majority of NiMH batteries are found in older devices or household apparatus. They charge faster than regular alkaline batteries. However, they may not be as efficient in longevity as Li-ion and LiPo batteries.

Supercapacitor

Supercapacitors differ in function from conventional batteries because they charge and release energy much faster. They are intended for quick charging. They do permanent duty for other batteries and special devices where a fast charge is needed.
