Wattsaving US10 EV Charging Station Review
It's got a nice design and a great charging cable, but there are still some improvements to be made.
Table of Contents:
There's an established electric vehicle charging brand in China called Wattsaving, and they provide charging equipment for many established EV manufacturers—like BYD, Zeeker, Xpeng, BMW, Nissan, and NIO. Founded in 2016, the company prides itself on producing a wide variety of products, including AC and DC charging equipment and bi-directional charging modules, with power output ranging from 1.5kW to 1200kW. They also hold over 50 patents and run more than 20 production lines. So this isn't a fly-by-night company.
The Wattsaving US10 is manufactured in China. This unit comes with a peak power output of 9.6 kW and a fixed 40-amp current, perfect for those who want a no-fuss charger for their EV. The Wattsaving US10 is intended to be a simple and affordable charging unit, two features that make it a compelling option for my comprehensive testing. Plus, it comes in four colors: purple, black, white, and blue. As the least expensive EVSE to be included in State Of Charge's reviews, I was eager to see how it would do.
Misses
- Not safety certified
- Poorly constructed wall bracket
- 2-year warranty
The Wattsaving US10 comes with the body of the unit, a mounting plate, a 24.6-foot charging cable with a nice, rubberized jacket and a quality SAE J1772 connector, a cable hook (though no connector holster), screws and drywall anchors, two RFID keys, and an installation guide. The unit can be ordered with either a NEMA 6-50 or a NEMA 14-50 plug.
The mounting plate has four holes to attach it to the wall, and you'll want to ensure that the flared ends of the openings are at the top so you can slide the bolts on the back of the unit into place. There's a single set screw on the side of the mounting plate, which you screw into place once the unit is hanging, meant to prevent it from sliding off. However, it doesn't work! I found that with any amount of force, I could slide the unit right past the set screw. If I owned this, I'd figure out another way of mounting it more securely because it could slide off and fall when you pull on the cable. I'd also not want to install this in a public place where it could be easily stolen.
Should you decide to hardwire the Wattsaving US10, I suggest that you do so with a professional electrician to reduce the possibility of a dangerous electrical failure. I personally recommend my YouTube channel sponsor Qmerit for that kind of job. As North America's leading provider of installation services for EV charging, home energy storage, and other electrification technologies, you can count on them to get the job done right.
The Wattsaving US10 is a 40-amp unit that can put out 9.6 kW of power. Unlike most modern Level 2 EVSEs, the US10 does not have an adjustable current. According to the manufacturer, you can expect to add up to 37 miles of range per hour, depending on your vehicle's efficiency.
Its IP65-rated enclosure means that the unit is dust-tight and watertight against light-pressure water spray. The US10 also has RFID access control, meaning you can control user access using the included RFID cards. Its operating temperature ranges from -22° F to 131° F (-30° to 55° C). Unfortunately, the unit isn't safety certified, and it only has a 2-year warranty.
Since the Wattsaving US10 doesn't come with a connector holster, I suggest checking out this inexpensive Lectron dock and hook combo to organize and protect your cable and connector.

Testing
Next comes the most important part of my review process: testing. My process emulates situations you might encounter during an EV charging station's everyday use, so you know what you're getting into when you buy one. Even a relatively inexpensive charger like the Wattsaving US10 costs a few hundred dollars, and that's a lot of money to waste should something break or not work as intended. Let's see how the US10 held up.
The Cable Deep Freeze Test
To check for cable pliability in extremely cold environments, I wound the Wattsaving US10 in tight loops and put it in a commercial ice cream freezer for more than 24 hours. When I took it out, the temperature measured -8° F (-22.2° C), well within the unit's operating temperatures. After remounting the unit, the cable remained nice and floppy, meaning that it should be a really good cold-weather cable. That's a pass from me.
The Connector Drop Test
While the connector was still frozen, I moved on to my Cold Connector Drop Test, where I dropped it repeatedly to the concrete floor of my garage from about waist height. I prefer metal tabs on my connectors, and the US10 reminded me why when I saw that its plastic tab had taken a little damage from the fall. It didn't break, though, so it earned a passing grade.
The Extreme Heat Test
While an EV charging station's ability to handle cold weather is important, those living in hotter climates know that the opposite is also true. To test the Wattsaving US10's ability to handle potential overheating, I put it in front of a heat lamp for about two hours, maintaining a surface temperature of about 120° F (48.89° C). Then, I plugged my Ford F-150 Lightning into the baking charger for another two hours. The Wattsaving US10 delivered its full 40 amps without issue, even though it reached a temperature of 155° F (68.3° C). That's another pass.
The Automatic Restart Test
With my Lightning still plugged in, I moved on to test the charger's ability to re-engage after losing power. Some EV charging stations get stuck in a fault state after an abrupt power cut, meaning your vehicle won't get charged. After cutting off power to the circuit and turning it back on, the Wattsaving US10 began charging again without any problems, meaning it also passed this test.
I gave the Wattsaving US10 3.45 stars out of 5 stars because of its terrible mounting plate, lack of safety certifications, and rather short warranty. It has a nice design and a great charging cable, but some improvements still need to be made.
The Wattsaving US10 is currently available for $199.99 on Amazon (as of January 21, 2026). Check out my full review in the video embedded above, and let me know what you think in the comments below.
