The higher the performance I sought, the more expensive they tended to be, and I couldn’t easily find the perfect unit.

Ms.ガジェット

I hear about GaN (Gallium Nitride), but I don’t really understand why it’s good.

Mr.ガジェット

GaN is the latest technology that achieves miniaturization and higher efficiency in chargers.

The UGREEN Nexode Mini 30W PD Charger solves such “troubles” of yours with the clear answer of being “equipped with a GaN II (Gallium Nitride) chip.”
Thanks to this next-generation technology, it achieves high power efficiency while suppressing heat generation, despite being amazingly compact.
I guarantee that for those of you who want to get the perfect balance of performance and price, there is no better choice than this.

Aren’t there too many types of chargers on the market, leaving you wondering which one is “actually” safe and “certain” to choose? Especially since you charge your smartphone every day, the “trouble” of wanting to choose a reliable product to avoid any unexpected trouble is a natural “fact.”

I understand your “trouble” very well.
Precisely because you are charging your precious device, the feeling of not wanting to “fail” with a cheap, low-quality product is “natural.”

I also feel that the “peace of mind” of genuine products is very important.
Especially if you are willing to pay “money” to get “certain” safety, you don’t need to hesitate.

The [Docomo Genuine] Portable AC Adapter OW03 brings you “unwavering peace of mind” through the strict quality standards and thorough after-sales support unique to NTT Docomo genuine products.

No More Guesswork! The Ultimate Guide and Truth About Choosing a 30W or Under Charger

Are you still harboring vague anxieties about which wattage or standard to choose so you don’t make a mistake when choosing a smartphone charger?

Ms.ガジェット

Honestly, I don’t really understand the difference between 20W and 30W, or what PD and PPS are, so I’m lost on which one to choose.

Mr.ガジェット

That’s okay. If you know the optimal way to choose, you won’t regret your charger selection again.

Here, I will thoroughly explain the way to choose the perfect charger for you in a way that can be understood without specialized knowledge.
I have condensed only the truly important points that I learned after testing dozens of chargers myself.

To definitely make your smartphone life comfortable, read on right now.

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

You know that “wattage (W)” refers to the maximum power that a charger can supply to a device, right? Generally, the higher this number, the faster the charging speed.

Even for the latest models like the iPhone 15 Pro Max, an output of 20W or more is recommended for optimal rapid charging.
On the other hand, when charging some laptops like the MacBook Air equipped with M1/M2 chips, if you have 30W of output, you can charge at a sufficiently practical speed.

Ms.ガジェット

I don’t really get what the optimal wattage output is for my smartphone.

Mr.ガジェット

If you match the charger’s output to the value required by the device, you can achieve high-speed charging without waste.

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

Checking the number of ports: Single port vs. multi-port, points for proper use

“Number of ports” refers to the number of USB connection terminals mounted on the charger.
There are mainly two types of ports on chargers: USB-C and USB-A.

USB-C ports support Power Delivery (PD) and allow for high-output rapid charging for iPhones, the latest Android smartphones, iPads, and laptops.
On the other hand, USB-A ports are suitable for charging conventional devices, wireless earphones, etc.
For example, if you want to charge your smartphone and wireless earphones at the same time, a product with 2 or more ports is definitely more convenient.

Ms.ガジェット

I have many things to charge other than my smartphone, so I’m confused about which port to choose.

Mr.ガジェット

If you choose the optimal number and type of ports to match your device configuration, you won’t be troubled anymore.

Choosing ports according to the type and number of devices you want to charge at the same time is the secret to establishing a comfortable charging environment.

Size and weight: Choosing based on portability! Explanation of GaN (Gallium Nitride) technology

“GaN (Gallium Nitride)” is a new material that replaces conventional silicon, and it is a technology that uses this material to dramatically miniaturize chargers and make them highly efficient.

Like the Anker 511 Charger (Nano 3, 30W), which is only about 40g, chargers that adopt GaN technology realize a powerful output of 30W with the weight of one egg.
Let’s end the practice of carrying around old chargers.
If it supports a foldable plug, it won’t take up any more space in your bag.

Ms.ガジェット

I hear about GaN often, but what is so great about it?

Mr.ガジェット

It’s truly next-generation technology that can provide high output while suppressing heat generation.

By choosing a small and lightweight charger that adopts GaN, you will be freed from the stress of carrying it, and your mobile life will be more comfortable than you can imagine.

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

“PD (Power Delivery)” is a rapid charging standard that uses a USB-C port and can supply power up to 100W.
“PPS (Programmable Power Supply)” is an extended feature included in PD 3.0, referring to a technology where the device being charged and the charger adjust voltage and current in real-time, charging with optimal power.

PD support is essential for rapid charging of iPhones and iPads.
Furthermore, for Android smartphones such as Galaxy and Pixel, using a PPS-supported charger enables faster and battery-friendly charging.
Cases have been reported where there is up to a 20% difference in charging speed depending on whether PPS is supported or not.
Are you still going to continue using a charger that doesn’t support PPS?

Ms.ガジェット

I understand PD support, but is it necessary to worry about PPS too?

Mr.ガジェット

If you want the best charging experience, PPS support is a point you should definitely grasp.

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

Safety features: Beyond PSE certification, points to look out for as an added plus

“PSE certification” is a national standard that indicates the safety of electrical appliances in Japan based on the Electrical Appliance and Material Safety Act.
In addition to this, various safety features are installed in chargers.

Taking PSE certification as a given, checking whether multiple safety features such as overcurrent protection, short-circuit protection, overvoltage protection, and overheating protection are installed is essential for choosing a charger without mistakes.
Products from major manufacturers such as Anker, CIO, and UGREEN have multiple layers of these protection features installed, protecting your precious devices even in the unlikely event of an incident.
I also always select products by checking if they are well-equipped with multiple protection features.

Ms.ガジェット

It’s hard to understand exactly what to look for when it comes to safety features.

Mr.ガジェット

Choosing a product equipped with multiple protection features provided by a reliable manufacturer is the most certain method.

Without being deceived by superficial cheapness, choosing a highly reliable charger equipped with multiple safety features is the only method to protect your device, and above all, your safety forever.

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

“Manufacturer reliability” refers to the comprehensive peace of mind provided by a company, such as product quality, support systems, and warranty periods.

It is a fact that proven manufacturers like Anker, CIO, UGREEN, and Docomo have thorough product quality control, and their support in case of any issues is very generous.
For example, Anker offers an 18-month warranty, and UGREEN and Docomo offer 2-year long-term warranties, which is nothing but an expression of confidence in their products.
Based on my experience, products from reliable manufacturers have fewer initial defects, and even in the unlikely event of an issue, they will respond smoothly.
Are you still going to gamble on a product from an unknown manufacturer?

Ms.ガジェット

Manufacturer selection just means it’s okay if it’s a major brand, right?

Mr.ガジェット

Choosing a major brand is a wise choice, but checking the warranty period and support content is the professional way to choose.

In order to continue using it with peace of mind for a long time, choosing a product from a manufacturer with a solid track record and support system holds the ultimate key to success in choosing a charger you won’t regret.
