TESSAN Surge Protector Power Strip 900J, 8 AC with 3 USB Ports (1 USB C), Flat Plug Review (2026)

Who this power strip fits

This TESSAN strip is built for a desk or dorm room that has run out of outlets, the common problem once a PC, two monitors, a lamp and a set of speakers are all plugged in around the same spot. Eight AC outlets is a generous count for a single strip, enough to cover a full desk setup with room to spare for the odd charger or fan. The flat plug head, just under a third of an inch thick, is specifically designed to slide behind furniture pushed close to the wall, a small detail that solves a real annoyance for anyone whose desk sits flush against a baseboard outlet. It suits home offices, dorm rooms and any desk in a tight spot more than a garage or workshop where fewer, higher-power outlets would matter more.

What 900 joules and the USB ports mean

The 900 joule rating describes how much energy the surge protector can absorb before it needs replacing, a mid-range figure that covers everyday power spikes well without reaching the highest joule ratings sold for sensitive server or AV equipment. Alongside the eight AC outlets, the strip includes three USB ports, two USB-A rated at 2.4 amps and one USB-C rated at 3 amps with power delivery, enough to fast charge a phone or lightly power a tablet. An on and off switch lets the whole strip cut power at once, useful for anyone who unplugs a desk setup at night rather than reaching behind furniture for each cord. Two mounting holes on the body also allow it to be screwed to a wall or the underside of a desk if a hanging strip is preferred.

Using it on a real desk

Outlet spacing on this strip runs close to two inches apart, wide enough that most standard wall-wart chargers and power bricks do not block their neighboring outlets, a common annoyance on cheaper strips with tightly packed sockets. Because the plug itself is flat, it is worth checking cord orientation when first plugging it into the wall, since flat plugs sometimes need to be flipped to sit correctly depending on the outlet. The strip should be kept away from standing water or damp areas, standard practice for any surge protector, and it is worth periodically checking that the surge protection light, where present, still indicates the unit is actively protecting connected devices rather than just passing power through unprotected.

How it stacks up against other strips

Among the surge protectors in this guide, the TESSAN sits mid-pack, behind options like the ALESTOR strip with 12 outlets and a much higher 2700 joule rating, or the HANYCONY strip which pairs a similar flat plug design with two USB-C ports instead of one. Those rivals suit setups with more devices or a preference for charging multiple USB-C gadgets at once. The TESSAN holds its own on value and the specific combination of eight generously spaced outlets with a flat, wall-hugging plug, a pairing not every rival offers together. For a typical single desk rather than a rack of equipment, the 900 joule rating and eight outlets are more than sufficient, even if the raw numbers look modest next to the highest ranked strips.

Verdict on whether to buy this strip

Choose this TESSAN strip if the desk setup needs several AC outlets plus basic USB charging, and if the flat plug design solving a tight-space outlet problem is a real consideration. Eight outlets with generous spacing cover a full desk of gear without crowding, and the on and off switch adds a convenient way to power everything down at once. Buyers who plan to charge more than one USB-C device at a time, or who want the highest possible joule rating for sensitive electronics, should look at the ALESTOR or HANYCONY strips ranked above it in this guide instead. For most everyday desk setups, though, this strip covers the basics well.
