Don’t Get Lost! The Ultimate Guide to Choosing a 30W or Less Smartphone Charger and the Truth

Are you still feeling uncertain about which smartphone charger to choose, and wondering what you should consider to avoid “failure”?

Here, I will thoroughly explain the “selection method” that will help you find the perfect charger, even if you don’t have any specialized knowledge.
I have condensed only the most important points that I have learned by trying dozens of chargers myself.

Read on now to surely make your smartphone life more comfortable.

How to choose wattage (W): What’s the difference between 20W and 30W?

“Wattage (W)” refers to the maximum power that a charger can supply to a device.
The higher this value, the faster the charging speed generally becomes.

Even with the latest models such as the iPhone 15 Pro Max, 20W or more of output is recommended for optimal fast charging.
On the other hand, if you are charging some notebooks such as the MacBook Air with M1/M2 chips, 30W of output is sufficient to charge at a practical speed.
You will no longer have to worry about battery life when you are out and about.

By choosing a charger with an output greater than or equal to the device’s required wattage, you can achieve the most efficient charging.

Check the number of ports: Single port vs. multi-port, points to consider when choosing

“Number of ports” refers to the number of USB connection terminals on the charger.
Chargers mainly have two types of ports: USB-C and USB-A.

USB-C ports support Power Delivery (PD) and can deliver high-power fast charging to iPhone, the latest Android smartphones, iPads, and notebooks.
On the other hand, USB-A ports are suitable for charging conventional devices and wireless earphones.
For example, if you want to charge a smartphone and wireless earphones simultaneously, a product with two or more ports is definitely more convenient.

Choosing a charger with the appropriate number of ports based on the type and number of devices you want to charge simultaneously is the key to establishing a comfortable charging environment.

Size and weight: Choose for portability! Explanation of GaN (Gallium Nitride) technology

“GaN (Gallium Nitride)” is a new material that replaces conventional silicon, and using this material allows you to dramatically miniaturize the charger and increase efficiency.

The Anker 511 Charger (Nano 3, 30W), which uses GaN technology, weighs only about 40g and is palm-sized, delivering 30W of powerful output.
Stop carrying your old charger.
If it also supports a foldable plug, it will be even more compact in your bag.

By choosing a small and lightweight charger that uses GaN, you can free yourself from the stress of carrying it around and make your mobile life more comfortable than you ever imagined.

Supported charging standards: Importance of PD (Power Delivery) and PPS support

“PD (Power Delivery)” is a fast charging standard that uses the USB-C port and can supply up to 100W of power.
“PPS (Programmable Power Supply)” is an extension included in PD 3.0 that allows the device and charger to adjust the voltage and current in real time, and is a technology that charges at the optimal power.

PD support is essential for fast charging iPhones and iPads.
Furthermore, with Android smartphones such as Galaxy and Pixel, using a PPS-compatible charger allows for faster and more battery-friendly charging.
There are also reports that the charging speed can differ by up to 20% depending on whether PPS is supported.
Will you continue to use a charger that does not support PPS?

By choosing a charger that supports not only PD but also PPS, you can maximize the charging efficiency of the various devices you use and reduce the load on the battery.

Safety features: Not only PSE certification, but also points to note

“PSE certification” is a national standard in Japan that indicates the safety of electrical products based on the Electrical Appliance and Materials Safety Law.

In addition to PSE certification, it is essential to check whether the charger is equipped with various safety features such as overcurrent protection, short circuit protection, overvoltage protection, and overheating protection.
Products from major manufacturers such as Anker, CIO, and UGREEN are equipped with multiple protection features, so they can protect your valuable devices in the event of an emergency.
I always check whether multiple protection features are in place when choosing a product.

Don’t be misled by superficial cheapness, and choose a charger with multiple safety features and a reliable manufacturer, which is the only way to protect your devices and your safety into the future.

Manufacturer reliability: Choosing a manufacturer for long-term peace of mind

“Manufacturer reliability” refers to the comprehensive peace of mind that a company provides, including product quality, support system, and warranty period.

Established manufacturers such as Anker, CIO, UGREEN, and Docomo have thorough quality control of their products, and their support is very generous in the event of a problem.
For example, Anker offers an 18-month warranty, while UGREEN and Docomo offer a 2-year long warranty, which is a demonstration of confidence in the product.
In my experience, products from reliable manufacturers have fewer initial defects, and you can get smooth support even if something goes wrong.

To use it with peace of mind for a long period of time, choosing a product from a manufacturer with a proven track record and a solid support system is the final key to success in choosing a charger that you won’t regret.
