Numark Mixstream Pro Go

The Numark Mixstream Pro Go is a standalone, battery-powered DJ controller listed at £655.00 and rated 4.3 out of 5 from 311 ratings. It sits 8th in this guide. The listing describes 6-inch jog wheels, a 7-inch touchscreen with adjustable brightness, onboard speakers with their own volume control, Wi-Fi streaming from Amazon Music Unlimited, Apple Music, TIDAL, Beatport, Beatsource and SoundCloud Go+, SD card and USB drive slots for playing without a computer, and wireless control of Philips Hue, Nanoleaf and DMX lights.

The gap on this page is the battery. The first bullet calls it a "battery-powered standalone DJ controller", the spec sheet confirms the power source as Battery Powered and says one Lithium Ion battery is included — but no playtime is given anywhere in the listing. The only runtime figure in the data we hold is a reviewer's "5hr+ battery life". Two other numbers are worth reading twice. The listing gives 4.2 kg as the item weight and repeats 4.2 kg in the dimensions line, 30 x 56.5 x 7.4 cm, which is worth knowing before you describe it as portable. And the five bars of the rating breakdown add up to exactly 100 while the same page reports 311 ratings, so those bars read as percentages rather than counts: eight of that hundred are one-star. There is also a small conflict worth flagging — the listing lists FX among its Serato DJ and Virtual DJ integrations, while one of the reviews shown on the page says the lack of effects is its only issue. Everything below comes from the Amazon listing, not from a test of our own.
