UltraProlink UM1049U 7-IN-1 Cube Extension Board with Surge Protection (4 AC Sockets, 3 USB)

UltraProlink UM1049U 7-in-1 Cube Extension Board with Surge Protection

The UltraProlink UM1049U packs seven ways to power and charge your devices into one compact cube. Four AC sockets and three USB ports sit on different faces of the body, so a desk that once needed a strip board, a separate USB charger and a tangle of adapters can run from a single wall outlet. Built-in surge protection guards the equipment plugged into it, and a 2 metre ISI-approved heavy-duty cable connects the cube to the wall, giving you useful reach across a workstation, studio desk or TV unit.

Key features

• 7-in-1 cube design, model UM1049U, combining AC power and USB charging
• 4 AC sockets rated for a combined load of up to 2500W
• 3 USB ports for phones, tablets and accessories
• Built-in surge protection and spike guard for connected equipment
• ISI-approved heavy-duty cable, 2 metres long
• Compact cube format that suits desks, media consoles and bedside tables

Four AC sockets and three USB ports in one cube

Most desks run more devices than the wall provides sockets for: a monitor, a laptop charger, speakers, a lamp, a phone and a tablet charger all competing for two outlets. The UM1049U answers that with four AC sockets for mains-powered equipment and three USB ports for the devices that otherwise each need their own wall adapter. Phones, earbuds, smartwatches and tablets can charge from the USB side while the AC side carries the bigger loads, which keeps the whole setup on one board instead of three.

Surge protection for connected equipment

Voltage spikes from switching, storms and an unstable supply can damage chargers, monitors and audio gear without any warning. The UM1049U includes surge protection, also described as a spike guard, between the wall and everything plugged into the cube. That does not make it a voltage stabiliser or a battery backup, and it cannot keep equipment running during a power cut. What it does is add a layer of protection against the brief, sharp spikes that are a common cause of silent equipment failure in Indian homes and offices.

Why the cube shape works on a desk

On a flat strip board, sockets sit in a row, and one bulky adapter can block the socket beside it. The cube layout spreads the outlets across different faces and angles, so plugs and power bricks point away from each other instead of fighting for the same space. The result is a smaller footprint on the desk and a better chance that all four AC sockets stay usable at the same time. The format also lifts connections off the floor, which suits media consoles and workstations where a trailing strip looks untidy and collects dust.

Setting it up and loading it safely

Place the cube on a dry, stable surface with the 2 metre cable routed so nothing pulls on it, then connect your heaviest loads first. The 2500W figure is the combined limit for everything on the AC side together, not a per-socket allowance, so add up the ratings of heaters, kettles and other high-draw appliances before assuming they can share the board. This cube is intended for electronics, chargers and everyday appliances within that combined limit. Keep the cable clear of sharp edges and trapped furniture points, and switch equipment off at the wall before rearranging plugs.

For a workstation, studio desk or entertainment unit that has outgrown its wall sockets, the UltraProlink UM1049U is a tidy, protected and practical way to bring power and USB charging together in one place.
