What are the differences between the SureCall Fusion5s 2.0 and SureCall Fusion5X 2.0?

Updated September 8, 2026

SureCall Fusion5s 2.0 (SC-Fusion5s2) vs. SureCall Fusion5X 2.0 (SC-FUSION5X2)

SureCall’s Fusion5s and Fusion5X cell phone signal boosters may look similar, but key differences between them will determine which will work best in your home or office.

Price

• SureCall Fusion5s: starts at $850
• SureCall Fusion5X 2.0: starts at $1,899

These boosters are separated by a $1,049 price difference, which puts them in different market segments: The Fusion5s is priced for large homes and small offices, while the Fusion5X is a commercial booster for small to mid-sized offices and buildings.

Booster design

• SureCall Fusion5s: Metal case
• SureCall Fusion5X 2.0: Metal case

The Fusion5s and Fusion5X share the same durable metal case with integrated heat sink.

Both boosters receive power from the same 12V/3A switching power supply, plugged into a 120V AC wall outlet.

Gain

Gain is the booster’s increase in the signal strength it receives from the outside antenna, measured in dB (decibels).

• SureCall Fusion5s: +72 dB maximum gain
• SureCall Fusion5X: +72 dB maximum gain

The Fusion5s and Fusion5X are both rated at the maximum gain the FCC allows for carrier-preapproved five-band cell signal boosters.

Uplink power

Uplink is the power output, expressed decibel milliwatts (dBm), that the booster uses to communicate with cell towers. The more uplink power, the greater the booster’s ability to communicate with distant towers.

• SureCall Fusion5s: 20.2 dBm average across all bands
• SureCall Fusion5X: 22.1 dBm average across all bands

The Fusion5X has 55% (1.9 dB) more uplink power than the Fusion5s. This makes the Fusion5X the better choice in areas where outside cell signal is weak.

Downlink power

Downlink is the power output, expressed decibel milliwatts (dBm), that the booster uses to communicate with cellphones and other cellular devices inside the building.

• SureCall Fusion5s: 9.2 dBm average across all bands
• SureCall Fusion5X: 14.9 dBm average across all bands

The Fusion5X has 5.7 dB more downlink power than the Fusion5s, about 3.7 times as much—a bigger “pipeline” that handles more simultaneous users and heavier data demands, which matters for busier offices.

Indicator lights

• SureCall Fusion5s: LED lights
• SureCall Fusion5X: LED lights

The Fusion5s and Fusion5X both have LED lights on the front to indicate the amplifier’s status on different cellular frequencies. (The user manuals for the Fusion5s and Fusion5X explain how to interpret the lights.)

Gain controls

• SureCall Fusion5s: Automatic gain control and manual gain control by band
• SureCall Fusion5X: Automatic gain control

Both the Fusion5X and the Fusion5s will automatically increase and decrease the gain on individual cellular bands to deal with overly strong or weak outside signal. The Fusion5s, however, also has five small knobs that can manually turn down or turn off the gain on individual bands of signal.

It’s not often that you need to manually adjust the gain of a cell signal booster, but if this capability is important in your situation, the Fusion5s is the better option.

Connectors

• SureCall Fusion5s: N connectors
• SureCall Fusion5X 2.0: N connectors

Both boosters attach to outside and inside antennas with commercial-grade N connectors.

Coax cable

• SureCall Fusion5s: 400-type (−3.7 dB signal loss per 100 feet)
• SureCall Fusion5X: 400-type (−3.7 dB signal loss per 100 feet)

The Fusion5s and the Fusion5X 2.0 are both 50-ohm systems that come standard with 400-type coax cable. Powerful Signal also offers upgraded half-inch coax cable with nearly half the signal loss of 400 cable, allowing for longer runs of cable in large buildings.

See our Complete Guide to Coax Cable for more information about types of cable for cell signal booster systems.

Antennas

• SureCall Fusion5s: Outside omni or directional, inside EDGE dome or EDGE panel (1–2)
• SureCall Fusion5X 2.0: Outside omni or directional, inside EDGE dome (1–4)

Powerful Signal’s standard Fusion5s kit includes your choice of 1 or 2 inside Top Signal EDGE dome or EDGE panel antennas. Our Fusion5X kit features 1 to 4 Top Signal EDGE dome antennas, since domes work best in most offices. Both antennas look neat and professional, regardless of the building type.

Best uses

• SureCall Fusion5s: Small offices with a handful of users and most large homes
• SureCall Fusion5X 2.0: Offices with more users and homes with weaker outside signal

The Fusion5s is usually the better solution for homeowners and for small offices with a handful of employees and/or customers who need improved cell signal. It’s also the best choice if you’re in the unusual circumstance of needing to turn down or turn off a specific band of cellular signal.

The Fusion5X is more powerful than the Fusion5s; it can cover more square footage and connect to more distant cell towers. This makes the Fusion5X the better solution for larger offices and for homes that are in remote areas with very weak outside cell signal.
