The EC Technology 22400 is a large, low cost USB-A power bank. It works well charging your Switch while asleep. But its performance is limited during play. It is good for Switch owners who want high capacity at a low cost where time isn’t a concern.

First Impression

The EC Technology 22400 has the same form factor as other 20,000mAh power banks. It is a bit longer and wider, but thinner than Anker’s 20100 models. A side button lights up four LED lights, which are a bit dim against the black matte finish. The three USB-A ports limit power output for the Switch. But USB-A vs USB-C of the same capacity is cheaper. On the side are two micro-USB ports, allowing for dual input charging of the power bank.

Power meter readings


The EC Technology 22400 is a typical 20,000+mAh USB-A power bank. It works as well with the Switch as any other USB-A power bank. It’s selling point is its price. Especially if you catch it on sale.

Like most any other USB-A power source it’ll charge the Switch fine while asleep. From 0-80% it charged the Switch’s battery 10% every 18 minutes. After 80% charging slows down, typical of lithium ion batteries. When the Switch was idle charging took twice as long, but still charged. With a game running it most likely won’t keep up with the power usage of the Switch. Reducing screen brightness and disabling Wi-Fi helps. With its high capacity it’ll provide about 5 hours of extended playtime.

Unlike most USB-A power banks, this one has two micro-USB ports. They work together, allowing you to double the charge into the power bank. You’ll need to use a multi-port USB charger or two USB chargers to use both input ports. But doing so reduces the power bank’s charge time by half.

Its USB-A ports are upside down. That doesn’t impact function. But I did catch myself having to flip the USB-A end of my cable every time I went to plug it in.

The Amazon listing has incorrect pictures. They are of the 2nd gen model, with a single micro-USB port and built-in flashlight. There are two micro-USB ports and no flashlight. The actual power bank looks like the pictures for the “26800mAH Black” model.

IEC Technology has U.S. based support contacts (web, email, phone) and warranty service.

Bottom Line

The EC Technology 22400 is as good as any other USB-A power bank for the Switch. It is best for Switch owners who want high capacity at a low cost, at the expense of a slower charge.
