TOPGREENER USB wall outlet chargers are quickly becoming a household necessity for home owners who want to improve their quality of living. These outlets allow you to charge smartphones, tablets, cameras, music players, and other small devices without the use of bulky adapters. One of the top models, TU21548A, was recently featured in an As Seen on TV commercial. You can view the commercial and read more about it in our previous article.
Most technical savvy individuals are up to date on the benefits of having USB outlet receptacles installed throughout the homes, but even the most well-informed users still have technical questions about choosing the right USB wall outlet. The following help guide lists the most common questions users ask before purchasing one of Top Greener’s Usb Outlets.
Do TOPGREENER USB outlets support fast charging or quick charging?
This is the most popular questions by consumers looking to purchase a USB outlet from Top Greener. The answer is “Yes, Top Greener USB outlets support fast Charging and quick charging”. These charging methods both achieve the same goal, but function differently. Because of the ambiguity of their names they can be mistaken as being one in the same. The next section of this guide aims to clarify the difference between the two.
What is Fast Charging?
Understanding fast charging and how it works requires some knowledge of electrical terms such as voltage (volts), amperage (amps), and wattage (watts). Volts are the measure of electrical pressure, amps are the measure of electrical current, and watts are a measure of electrical power that is determined by multiplying the volts and amps together. An easy way of understanding how they work is to compare them to a garden hose. The water pressure in the hose would be equivalent to the volts; the flow rate would be the amps, and the volume of the water exiting the hose would be the watts.
A USB outlet that is capable of fast charging delivers more amperage than the standard USB output of 0.5A. For example, TOPGREENER’s TU21548A amperage power rating is 2.4 amps per USB port. It is important to note that while an outlet like TU21548A provides 2.4 amperage output, the total power
drawn from the receptacle will still depend on the device limitations. For example, if an Apple iPhone is connected to the a 2.4A outlet, but has an amperage limit of 2.1A then that unit will only draw the (2.1A) amount dictated by the phone’s software. Device makers can an also place limitations on when Fast Charging starts and ends during a charging cycle. For example, Apple has safety limitations that allow fast charging when a battery is between 0 and 79 percent, but this stops once it reaches 80 percent.

What is Quick Charging?
The chipmaker Qualcomm developed the Quick Charge technology to work with Snapdragon processors. What makes this different than Fast Charging technology is the power that Quick Charge dictates to be used by the devices during the charging cycle. A Quick Charge USB receptacle allows 5v, 9V, or 12V to be drawn. The maximum power output is 18W. Using Intelligent Negotiation for Optimum Voltage (INOV) the charger pushes power to the device as needed to reach the charging time. Qualcomm Quick Charge 3.0 enabled devices reach a 50 percent charge in half an hour, and full charge in one hour. Most smartphones take about 2 hours to charge when using standard USB charging.
When comparing Fast Charge and Quick Charge it is important to identify which type is being described. Since the words fast and quick both imply the same thing you will come across sellers who label a Fast Charge outlet as being a Quick Charging one and vice versa. The best way to differentiate between the two is by looking for the Qualcomm Branding on the device. TOPGREENER Quick Charge USB outlets clearly show the branding on the front.

How fast will TOPGREENER USB outlets charge my device?
Charging time for devices will vary depending on the manufacturer specifications, battery capacity, and adapter. Generally, you can expect a USB wall outlet with Fast Charging or Quick Charging technology to get your battery to 60-80% charge in half of the time as a normal USB charger.
What is USB Power Delivery?
USB Power Delivery or USB-PD is a growing industry standard for power management through USB charging. The evolution of USB ports from 1.0 to 2.0 to 3.0 and finally 3.1 was primarily focused on achieving faster data transfer. With each new addition, power was increased to meet the data transfer goal. As more devices became dependent on USB charging rather than data transfer, specifications were needed to determine what the optimum output should be for USB powered devices. Manufacturers have typically stayed closer to low level power outputs to prevent overcharge accidents, but back in 2016 the USB Implementers Forum (USB-IF) released the Power Delivery Specifications. These new guidelines made way for manufactures to make USB ports capable of powering devices that required up to 100 watts. Small devices don’t require this amount of juice, but with USB-PD an outlet could safely charge a smartphone, and still be powerful enough to charge a laptop. But how could a laptop be charged using the same adapter, outlet, or cable as a smartphone? The answer came with the introduction of USB Type-C. The design behind USB Type-C combined all previous styles into one that would support high data and power output.
In short, USB-PD is technology used in devices that support USB TYPE-C to achieve a universal way of transferring data and powering multiple devices. For example: if you have an Apple iPhone 8, but your laptop is a Google Chromebook, you could charge both these devices through a USB TYPE-C cable that supported USB power delivery.
What other methods of USB charging are available?
The marketplace is not limited to Fast Charging and Quick Charging technology. Many manufacturers have created their own versions of these high-speed options. Here is a list of some of the most popular ones:
Apple Fast Charging
Samsung Adaptive Fast Charging
MediaTek Pump Express
OnePlus Dash Charge
These alternatives work on the same concepts of Fast Charging and Quick Charging, but have different voltage, amperage, and wattage regulations. Manufacturers have developed their own proprietary charging methods too so that consumers will only purchase chargers that are compatible with their technology. This can be a downside for consumers. It is best to look for a phone or device that is universally compatible with faster charging methods. The Fast Charge technology in Top Greener’s TU21548A is accepted by virtually every small device on the market.
How easy is it to install TOPGREENER USB outlets?
Customers who have purchased outlets such as the TU21548A have found that installation can be quick for a novice. Many have shared their experiences through Amazon reviews. Here are some of the Top Reviews:
Very easy to install! – By Rodel
Work great! Installed them myself… – By Surfer Girl
No Power Draw when USB Unplugged – By Kelliar (TOP 500 REVIEWER)
These are great. They charge phones fast – By Walter Dzierga
These customers were able to install the outlets themselves using the included instructions, or online videos. It is still recommended to consult with a qualified electrician before performing any home improvements involving electrical wiring.
Are TOPGREENER USB outlets safe to use in my home?
TOPGREENER USB wall charger outlets are safe to use in residential settings, and commercial ones like airport charging stations, lobbies, and waiting rooms. They are UL listed, and meet 2011 NEC code compliance for tamper-resistant receptacles. Learn more about tamper-resistant outlets in my previous article about “How to make your home more child safe”.
The USB outlets from TOPGREENER also have several built-in safety features such as temperature control, overcharging protection, short circuit protection, overvoltage protection, current stabilizer, and surge protection. The back cases for the outlets are also fire resistant.
Additional information to consider
When buying electronics most consumers rely on blind faith that the seller has provided all the necessary information they need. This assumption is true for most, but there are many companies that do not fully disclose all the information that helps in the decision making process. TOPGREENER is dedicated to assisting all product inquiries. You can get fast technical support through their social media accounts, or at the website www.topgreener.com.
