2nd Place: CIO USB Rapid Charger PD20W
With your current charger, are you unable to charge your earphones or another device while charging your smartphone, feeling like you are “ultimately” wasting time waiting for charges? Especially when the batteries of multiple devices drop simultaneously while you’re out, the “trouble” of wondering which one to prioritize is a very common scenario.
I sympathize with that “trouble” of yours.
You want to make the most of your precious time, and naturally want to avoid having your activities restricted because of charging.
Ms. GadgetI want to charge multiple devices at the same time, but I’m worried the charging speed will drop.
Mr. GadgetWith CIO’s dual-port charger, you can efficiently charge multiple devices without slowing down.
This CIO USB Rapid Charger PD20W blows away that “trouble” with the unique solution of equipped USB-C and USB-A dual ports.
You gain the “freedom” to charge two devices simultaneously and efficiently—such as a smartphone and wireless earphones—using just a single wall outlet.
As someone who often carries multiple devices myself, I feel that the convenience of these dual ports is an “amazingly” huge benefit.
This compact charger truly proves its worth when wall outlets are limited, such as in accommodations or cafes.
No more “wasted” time wondering which device to charge first.

Do you still harbor vague anxieties about avoiding mistakes when choosing the wattage or standard for your smartphone charger?
Ms. GadgetHonestly, I don’t really understand the difference between 20W and 30W, nor what PD or PPS are, so I’m confused about which one to choose.
Mr. GadgetDon’t worry. Once you know how to choose the optimal one, you will never regret your charger choice again.
Here, I will thoroughly explain how to choose the perfect charger for you in a way that is easy to understand even without specialized knowledge.
I have condensed only the truly important points I learned after testing dozens of types of chargers.
Let’s read on right now to reliably make your smartphone life comfortable.
How to Choose Wattage (W): What’s the Difference Between 20W and 30W
You already know that “wattage (W)” refers to the maximum value of electrical power a charger can supply to a device, right? Generally speaking, the higher this number, the faster the charging speed.
Even for recent models like the iPhone 15 Pro Max, an output of 20W or higher is recommended for optimal rapid charging.
On the other hand, when charging certain laptops such as the MacBook Air equipped with M1/M2 chips, an output of 30W provides sufficiently practical charging speeds.
Ms. GadgetI still can’t quite picture how many watts is optimal for my smartphone.
Mr. GadgetBy matching the charger’s output to the value required by your device, you can achieve fast charging without waste.
By checking your device’s required wattage and choosing a charger with equal or greater output, you achieve the most efficient charging.
Checking Port Count: Single-Port vs. Multi-Port, When to Use Which
“Port count” refers to the number of USB connection terminals equipped on a charger.
Chargers mainly feature two types of ports: USB-C and USB-A.
USB-C ports support Power Delivery (PD) and enable high-output rapid charging for iPhones, the latest Android smartphones, iPads, and laptops.
Meanwhile, USB-A ports are suited for charging legacy devices or wireless earphones.
For example, if you want to charge your smartphone and wireless earphones simultaneously, a product with 2 or more ports is drastically more convenient.
Ms. GadgetSince I have many things other than my smartphone to charge, I get confused about which ports to choose.
Mr. GadgetOnce you choose the optimal port count and types to match your device configuration, you won’t be troubled anymore.
Choosing ports according to the types and quantities of devices you want to charge simultaneously is the secret to establishing a comfortable charging environment.
Size and Weight: Choose Based on Portability! Explanation of GaN (Gallium Nitride) Tech
“GaN (Gallium Nitride)” is a new material replacing conventional silicon. Using this material is a technology that dramatically miniaturizes chargers and makes them highly efficient.
Like the Anker 511 Charger (Nano 3, 30W) at just about 40g, chargers adopting GaN technology achieve a powerful 30W output at the weight of a single egg.
Let’s put an end to carrying around outdated chargers.
If it supports foldable prongs, it takes up even less space in your bag.
Ms. GadgetI keep hearing about GaN, but what makes it so amazing anyway?
Mr. GadgetIt’s truly next-generation technology that can deliver high output while suppressing heat generation.
By choosing a compact, lightweight charger adopting GaN, you will be freed from the stress of carrying, and your mobile life will become comfortable beyond imagination.
Supported Charging Standards: The Importance of PD (Power Delivery) and PPS Support
“PD (Power Delivery)” is a rapid charging standard utilizing USB-C ports, capable of supplying power up to 100W.
“PPS (Programmable Power Supply)” is an extended feature included in PD 3.0, referring to technology where the charging device and charger adjust voltage and current in real-time to charge with optimal power.
PD support is essential for the rapid charging of iPhones and iPads.
Furthermore, for Android smartphones such as Galaxy and Pixel, using a PPS-supported charger enables even faster and battery-friendly charging.
Cases have been reported where the presence or absence of PPS support creates up to a 20% difference in charging speed.
Will you really keep using a charger that doesn’t support PPS?
Ms. GadgetI understand PD support, but do I really need to worry about PPS as well?
Mr. GadgetIf you want the ultimate charging experience, PPS support is a point you should definitely secure.
By choosing a charger that supports both PD and PPS, you maximize charging efficiency for the diverse devices you use while reducing the load on the battery.
Safety Features: PSE Certification, Plus Alpha for What Else to Look For
“PSE certification” is a national standard indicating the safety of electrical products in Japan based on the Electrical Appliance and Material Safety Law.
In addition to this, chargers are equipped with various safety features.
Beyond PSE certification as a given, checking whether multiple safety features such as overcurrent protection, short-circuit protection, overvoltage protection, and overheat protection are installed is indispensable for choosing a trouble-free charger.
Major manufacturer products like Anker, CIO, and UGREEN are equipped with multiple layers of these protection features, protecting your precious devices in the event of an emergency.
I always check whether robust multi-protection features are included when choosing products.
Ms. GadgetIt’s hard to understand where specifically to look when it comes to safety features.
Mr. GadgetChoosing products equipped with multi-protection features provided by reliable manufacturers is the surest method.
Instead of being misled by superficial cheapness, choosing a highly reliable charger equipped with multi-layered safety features is the only way to protect your devices and, above all, your safety well into the future.
Manufacturer Reliability: Choosing a Brand for Safe, Long-Term Use
“Manufacturer reliability” refers to the comprehensive peace of mind provided by a company, including product quality, support systems, and warranty periods.
Proven manufacturers like Anker, CIO, UGREEN, and docomo thoroughly manage product quality, and it is a “fact” that support is extremely attentive when something goes wrong.
For example, Anker offers an 18-month warranty, while UGREEN and docomo offer 2-year long-term warranties, which are nothing less than an expression of confidence in their products.
In my experience, products from reliable manufacturers have fewer initial defects and are handled smoothly in the unlikely event of an issue.
Are you still going to roll the dice on a product from an unknown manufacturer?
Ms. GadgetWhen it comes to choosing a manufacturer, as long as it’s a major brand, it’s fine right?
Mr. GadgetChoosing a major brand is a wise choice, but a pro’s selection method is to also check the warranty period and support details.
To continue using products safely and for a long time, choosing products from manufacturers with a solid track record and support system holds the ultimate key to success in regret-free charger selection.
