Manufacturer description

The ProtoArc EM15 is a tri-mode wireless mouse for people who work across more than one device. You can pair up to three devices over Bluetooth, a USB-A receiver and a USB-C receiver, then switch between them with one button. Both receivers sit in a compartment on the back of the mouse, so they travel with it. At 68g, the EM15 is light enough to carry in a laptop bag and to use for long work sessions. It measures 4.9 x 2.5 inches, a full-size shape built for a palm grip in medium to large hands, so your fingers have more room than on a compact travel mouse. The clicks are silent, which suits…

SpecPicks Verdict

SpecPicks scored ProtoArc EM15 USB C Mouse using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. ProtoArc's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Can the ProtoArc EM15 connect to more than one computer at once?

Yes. It stores up to three connections: Bluetooth, a USB-A receiver and a USB-C receiver. A single button switches between them, so you can move between a laptop, a tablet and a desktop.

How long does the EM15 battery last on a charge?

ProtoArc rates it at about 15 days of use and up to 200 days of standby after a 2-hour charge with the included cable. The mouse also goes to sleep after a few minutes of inactivity to save power.

Is the ProtoArc EM15 a good fit for small hands?

It is designed for medium to large hands. At 4.9 x 2.5 inches it is a full-size mouse with a palm grip, so people with small hands may find a compact mouse more comfortable.

Does the EM15 work with a MacBook or an iPad?

Yes. In Bluetooth mode it works with MacBook Pro/Air, iMac, iPad Pro/Air/Mini, iPhone and other Bluetooth devices. It also supports Windows 7/8/10/11/XP, macOS, Android and Chromebooks.

Is the ProtoArc EM15 completely silent?

The left and right clicks are silent. ProtoArc states that the middle scroll wheel is not quiet, so scrolling still makes some sound.
