USB wall chargers are popular options for charging your smartphone and other electronic devices. They’re handy to have around the house when you need them. But just like any other technology, USB wall chargers have their drawbacks. Let’s look at some reasons to avoid a USB wall charger, but first, here’s some background on them.

Some Background on the USB Wall Charger

USB means Universal Serial Bus, an industry standard for the interfaces and protocols to connect, transfer data, and host power. USB aims to standardize connecting peripherals, like keyboards, to computers. They communicate with and between devices, as well as supplying electric power. Additionally, USBs are a common way to power or transfer data to/from cameras, game consoles, power banks, and other devices.

Four generations of USB specifications exist, with USB4 as the newest. It supports Thunderbolt 3 protocol tunneling, like PCI Express and DisplayPort. And it adds the ability for host-to-host interfaces.

When many electronics first came out, they had proprietary chargers and cables. But that added to electronic waste as devices wore out and consumers replaced them. So companies began shifting toward universal chargers as a way to eliminate e-waste.

The USB PD (power delivery) standards raise power levels to 100 watts, so more devices can now charge through USB ports. Even Nintendo Switch and portable monitors charge through USB. In addition, the new standard lets power charge both ways. One port was the power source in the past, while the other received power. But now your phone or other device can deliver power instead of only receiving it.

Reasons to Avoid a New USB Wall Charger

Long ago, in technology’s dark ages (aka 2007), the Battery Charging Specification standardized faster ways to charge USB devices through wall chargers or by sending more amps to your PC’s ports. And that made a difference in keeping wall chargers safer. But there are still valid reasons to avoid a new USB wall charger.

Quick Charging Variances

Some fast-charging USB wall chargers feature Qualcomm technology, so you get speedy device charges. But not all chargers are made equally. So check to see if your selected charger has the latest technology and a higher maxim output (V/A – volts to ampere.) For example, 5V/1A means it delivers a max power of five watts, which is slow but suitable for overnight charging.

Multiple Ports Slow Charging Down

You might like the convenience of plugging multiple devices into one charger. But that might actually slow your charging down. Generally, a USB wall charger discloses the total wattage it supplies, but that doesn’t mean each port gets the entire amount.

So if your charger has four USB ports and puts out 100 watts, each port gets 25 watts. On the other hand, single port chargers get the whole charging capability, so they work faster.

Charger Damages Your Device

In extreme cases, low quality USB wall chargers without adequate safety measures could even start fires.

There is the potential for some USB wall chargers to damage your phone or device if they don’t have current control. Additionally, some cheaper chargers don’t always meet safety standards and could start a fire if the worst happens.

So verify the wattage as well as whether the charger and cable have the required technology to protect your devices. Newer chargers can recognize your plugged-in device to provide the optimal current for fast charging.

Older Devices Might Not Charge Properly

Modern USB devices should work fine with high-amp USB ports, so you’ll benefit from fast charges. But older products (like some e-readers or older generation tablets) may not work with USB ports using the Battery Charging Specification. So you might need an old-school USB 1.0 or 2.0 PC port.

USB-C Charging Is Faster and Safer

Many smartphones no longer come with dedicated chargers, making it harder to choose the proper one. But a great reason to avoid a new USB wall charger is that USB-C charging is faster and safer. It’s the new universal charging standard, and it’s three times faster than Apple’s free older iPhone charger. But the best thing about USB-Cs is that they are inherently smart, so they recognize your device and charge accordingly.

Frequently Asked Questions

Are your USB outlets outdated?

USB outlets are not outdated. Instead, they’re growing more popular. Charging your device through a wall connector or USB port is easier than ever. There are ports on lamps, charging bases, and of course, on your laptop or PC.

Why do USB wall chargers quit working?

Here are some basic things to check when USB wall chargers stop working. Verify your wall socket is on if it is a GFCI socket. Plug something else into the socket to make sure it works. If the test device works, your charger could be damaged. Try the same with your device’s power port to ensure it is in working order.

What’s the difference between USB wall chargers?

USB chargers, connectors, and cables differ in the power supply they offer. And one laptop or PC may vary in USB power output from another similar system. High-quality products meet safety standards and use charge-managing technology. So consider your specific devices, power outputs, and the amperage of your supplies to determine the speed of a recharge.

Are cheap wall chargers safe?

Some cheap wall chargers may vary in power outage, potentially damaging your device. Hopefully, your phone will stop charging when the power is full, as intended. But in the worst-case scenario, a cheap charger may not meet safety standards, so it might give you an electric shock or potentially start a fire. Buying a cheap charger comes with risks.

Will older chargers charge more slowly?

Older five-watt chargers don’t have the newest hardware and technology, so they likely won’t deliver power at fast rates. Therefore, they will charge more slowly than an upgraded fast charger and cable.
