Razer’s Mamba Hyperflux mouse and the Firefly Hyperflux charging-pad combo seem like science fiction. It is a wireless mouse without a battery. Basically, it is a real piece of new technology that is complete with a few first-gen flaws.
Razer’s Hyperflux, at least in concept, is actually the most futuristic. In terms of usage, it is similar to Logitech’s Powerplay—a charging field basically is projected across a specially equipped version of the Razer’s LED-laden Firefly mouse pad. The mouse (an adapted Mamba) has no battery inside. A capacitor rather stores enough charge in order to power the mouse for 15 seconds approximately.
The Mamba Hyperflux, in other words, functions as long as it is on the Firefly Hyperflux mousepad. The users could notice a little green light on both the mouse and the mouse pad depicting that the Mamba is receiving power. When the two are separated, the light turns off, and the mouse would run for 15 more seconds and then automatically die.
It does sound strange at first. Dangerous, even—that does not at all appear to be reliable! Razer’s wager essentially is that anyone purchasing the Hyperflux would hook it up at a desk and never require moving it, and Razer probably is right.
The Mamba Hyperflux and the G903 essentially are identical for day-to-day use then. The users plug in the mouse pad, they put the mouse on the mouse pad, and it starts working. The Mamba Hyperflux, under the hood, is feeding the charge through a capacitor while the G903 cycles its battery in between 85 and 95 percent charge.
The problem with the Hyperflux is that when issues do arise there is absolutely nothing to fall back on. Both the Powerplay and the Hyperflux have a quirk where the charging field does not quite encompass the whole mouse pad surface. The charging field is an oval, whereas both the Powerplay and the Firefly Hyperflux mouse pads slightly are bigger rectangles. In both the cases, the charging field does not reach the corners.
But with the Powerplay that is no big deal! If the users leave a G903 accidentally on the edge of the mousepad, it switches seamlessly to running off the battery. With the Mamba Hyperflux, it just dies. Reconnecting the Mamba Hyperflux consumes a lot of time too—upwards of about six seconds to move the cursor after a full shutdown, with the mouse initially regaining power and then presumably pairing again.
So now the question is if that is going to be a common occurrence. The answer is, probably not. As long as the users make sure that the mouse is fairly well-centered on the mouse pad, the Mamba Hyperflux must work fine. The users could also lift-and-adjust the mouse to their heart’s content without worrying it would run out of charge. That action consumes a second at best, so the users are safe.
It is a great mouse too. It is a comfortable right-hand scoop shape, has a tilt-wheel, glides nicely, and despite the rubber grips on the side they still are very comfortable. The Mamba Hyperflux has an optical sensor, presumably a version of the PWM3389.
