What to Look For in a best battery charger for rechargeable batteries?

To buy any product seems easy, but to choose the best one is not straightforward. The time you take to research its outcome is significant. The same matter also comes to best battery charger for rechargeable batteries of 2023 that we include in this article. But you can relax instead of spending too much time learning the products. It’s our duty!

Here are the main features of best battery charger for rechargeable batteries that all of you guys should keep in mind when deciding to make a purchase:

Plug Format

Make sure that your charger is compatible with local sockets. You'll have to bring an adapter if you don't want to be bothered by the inconvenience of having to take it with you on your trip.
You can change your plug with chargers that have a modular design. They are more costly and you won't be traveling a lot with them.

Charging Speeds And Standards

While the charging speed for smartphones and other devices is expressed in Watts (W), most power banks also list the voltage (V), as well as the amperage. You can easily calculate the wattage by simply multiplying voltage and amperage. The maximum charge rate depends on the device you are using, what standards your phone supports and which charging cable you use. Most smartphones (including Apple's iPhones) support Power Delivery (PD), which charges at approximately 20 W. Some phones (such as Samsung's Galaxy S series) support a supplementary PD protocol, called PPS, that can charge up to 25W. Other phones support Qualcomm's Quick Charge (QC). Other fast-charging protocols exist, but power banks will not be available unless the manufacturer of your smartphone supports them.

Charging Capacity

Four rough groups are used to package the chargers. Most basic chargers come in tiny cubes measuring one inch with one USB port and fixed prongs at one end. These chargers usually offer 18W, but they are typically half the power of an average smartphone. These next groups come in larger sizes, measuring 2x2x2inches. They have one or two ports and are rated between 30-45W. This third category is for larger tablets and laptops, and they are rated at 60W. The largest and most costly chargers can provide 100W, and they often come with several USB ports.

USB Ports

Although most products only have one USB-C port on them, there are many that offer multiple ports. You can charge older accessories with chargers that mix USB-A/USB-C ports. Some also have different USB-C power levels, so be mindful of what you plug in. The extra ports can be very restrictive in terms of use, as you must share power between multiple devices. This makes it less convenient to have a fast charger.


Amperes are the units of current in a charger. This value is used to measure the speed of the charger's charging. Chargers with the highest quality can charge at 2.5A, or more for more powerful models. A high-amperage charger will not cause damage to your mobile phone.
Voltage is a variable. It affects charging speed and also the charge time. But unlike amperage it must match the voltage on the phone. This will avoid any irreparable harm. The voltages vary from 5V to 12V.

Wireless Charging

Wireless charging is also very popular. It allows compatible devices to be powered up without the use of a cable. All you have to do is place them on top the battery. Some battery packs can support Qi, which is the standard used for compatible Apple phones and Samsung smartphones. Apple's MagSafe charging technology was introduced with the iPhone 12. A range of MagSafe compatible batteries packs can be charged at up to 7.5W.


Although absolute size does not matter, smaller chargers are preferred over bigger ones. You can accept smaller chargers if your device requires more power, ports or both, however, smaller is always better.

Fast Charging

Amperage and voltage are the two main measurements of battery output. The voltage and amperage are the amounts of energy in the battery. Wattage is the measurement of total power. It's calculated by multiplying volts with amps. Manufacturers can increase the wattage to make the device charge more quickly.

Charging Circuitry

Chargers have used silicon-based circuits for years to connect with portable devices. Modern devices use gallium nitride, or GaN as their base. It has two major advantages. First, it conducts electricity better than silicon. Second, it heats less. This means that chargers are smaller and can deliver the same power, but they run cooler. It is especially important for large-power models. The GaN chargers may be more expensive, but they are worth the extra money if you have the option. Anker says they're now working on the third generation of GaN chargers.

Charger Cable

A charger that has a very short cable is the most dangerous thing you could do. It is very annoying to need to search for a safe place to leave your phone charging.
Some chargers allow you to separate the charging cable from the adapter. If you require a longer cable, these chargers can be separated from the power adapter. Make sure that the cable you choose is high quality.
It is important to ensure that the cable you purchase has a high quality finish.


How do I know when my rechargeable battery is fully charged?

Most battery chargers have an indicator light that will show when the battery is fully charged.

How often should I charge my rechargeable battery?

It is recommended to charge a rechargeable battery when about 70% to 75% of the capacity has been consumed. Rechargeable batteries are damaged by over-discharging them, which will have an impact on the service life of the batteries and could cause leakage.

Is it safe to leave a battery charger plugged in all the time?

It is not recommended to leave a battery charger plugged in all the time as this can cause damage to the battery or the charger. It is best to unplug the battery charger after use.

How long should I charge my batteries?

The amount of time required to fully charge your batteries will depend on the type and capacity of the batteries you are using. Refer to the instructions that came with your battery charger for specific charging instructions.
