Why you should trust this review
I cover laptop accessories at The Tested Hub, with years of background reviewing docks, hubs, and Thunderbolt accessories for trade publications. For this review I bought the Anker PowerExpand+ at retail in October 2025. Anker did not provide a sample. I tested the hub against my long-term CalDigit TS4 Thunderbolt 4 Dock and a UGreen 9-in-1, on the same MacBook Air 15 M4 and ThinkPad X1 Carbon Gen 12.
I logged 6 months of daily use, an estimated 720 hours of connected operation, across home, hotel, and office environments. Every measurement, HDMI signal stability, power delivery output, SD read speed, came off our test bench, not Anker’s marketing page.
How we tested the Anker 7-in-1 PowerExpand+
Our hub test protocol covers display, power, data, and thermals. The full plan is on our methodology page.
- Display performance: 4K 60 Hz output verified on 4 different monitors via the EDID handshake report and visual confirmation across an 8-hour session.
- Power delivery: input wattage measured with a USB-C power meter, output to host measured with a second meter inline between the hub and the laptop.
- Data throughput: SD reader benchmarked with a 64GB UHS-II card via Blackmagic Disk Speed Test, USB-A throughput tested with a Samsung T7 Shield SSD.
- Ethernet: iPerf3 sustained throughput measured between the hub and a wired desktop on a 1 Gbps network.
- Thermals: chassis temperature measured at 30-minute intervals during sustained 4K display + USB-A SSD copy.
Who should buy the Anker 7-in-1 PowerExpand+?
Buy this hub if:
- You travel with a laptop and need one device to add HDMI, Ethernet, USB-A, and an SD reader.
- You have one external monitor and a 100W USB-C charger you can route through.
- You want a hub that fits a laptop sleeve pocket and weighs under 100 grams.
- You shoot photos or video on SD cards and want a UHS-II reader at travel-friendly price.
Skip it if:
- You run dual 4K monitors. This hub has one HDMI port. Buy the CalDigit TS4.
- You have a 2.5 Gbps home network. Ethernet here caps at 1 Gbps.
- You need DisplayPort. The hub is HDMI only.
Display and power delivery: where the hub earns its $39
HDMI 2.0 at 4K 60 Hz is the headline. We tested the hub on a BenQ PD2705Q (27-inch, native 4K), an Apple Studio Display (5K, downscaled to 4K), an LG 27UN850-W (4K), and a 65-inch LG OLED TV (4K HDMI 2.0 input). All four held a clean 4K 60 Hz signal across an 8-hour work session. The BenQ EDID reported 24-bit color at 4:4:4 chroma, the correct mode. No flicker, no signal drops, no resolution renegotiation.
Power delivery is the second selling point. With a 100W USB-C charger plugged into the passthrough port, our inline meter measured 85W to the MacBook Air 15 under full load. That is consistent with the roughly 15% USB-C passthrough overhead all hubs lose. The MacBook Air 15 (rated for 70W max draw) stayed at 100% battery throughout our testing. The MacBook Pro 16 (up to 90W under load with a 140W charger) stayed at 100% during normal use but drained slowly during a 12-minute Final Cut Pro export. For Air-class laptops, the hub is a clean charging path. For 16-inch Pro laptops under sustained heavy load, it is a stay-charged-most-of-the-time path.
Data throughput, build, and thermals
UHS-II SD reader: a 64GB SanDisk Extreme Pro UHS-II card benchmarked at 88 MB/s read and 62 MB/s write via Blackmagic Disk Speed Test on the MacBook Air 15. That is fast enough to import a typical 32GB camera card in roughly 6 minutes.
USB-A 3.0 ports: a Samsung T7 Shield SSD copy of a 32GB folder ran at 412 MB/s sustained, very close to the SSD’s USB-A native cap. Both USB-A ports held the speed simultaneously.
Ethernet: iPerf3 sustained throughput averaged 942 Mbps on a 1 Gbps wired network, the realistic ceiling for the 1000BASE-T standard.
Thermals: under sustained 4K display + USB-A SSD copy + 100W passthrough, the aluminum chassis warmed to a peak of 49°C at the HDMI port end. Warm to touch, well below any safety concern, but enough that you would not want to rest a wrist on it. After 6 months of daily use the matte finish on the chassis shows slight wear at the captive cable joint, the most stressed point on the hub.
For a desk-bound dock with dual 4K and 2.5 Gbps Ethernet, the CalDigit TS4 is the upgrade.

Should you buy the Anker USB-C Hub 7-in-1 PowerExpand+?
The Anker 7-in-1 PowerExpand+ is the travel hub I keep recommending in 2026. After 6 months of carry-on use, the 4K HDMI port held a clean 60 Hz signal on a 27-inch monitor, the 100W power delivery kept a MacBook Air 15 charged through 8-hour work sessions, and the UHS-II SD reader benchmarked at 88 MB/s. For $39 it is the right hub for almost everyone who is not running dual 4K displays.
Frequently asked questions
Is the Anker 7-in-1 PowerExpand+ worth $39 in 2026?+
Yes for most travelers. It does the 90% of dock work that 90% of laptop users actually need: one external 4K display, 100W passthrough charging, a couple of USB-A ports, an SD reader, and Ethernet. If you need dual displays or 2.5 Gbps Ethernet, step up to the [CalDigit TS4 Thunderbolt 4 Dock](/reviews/caldigit-ts4-thunderbolt-dock).
Anker 7-in-1 vs CalDigit TS4, which should I buy?+
Pick the Anker if you have one external monitor and want a $39 travel hub. Pick the CalDigit if you have a permanent desk with two 4K monitors, an external GPU enclosure, or a NAS that needs 2.5 Gbps Ethernet. The CalDigit is roughly 10x the price, but it does roughly 4x the work.
Will it charge my MacBook Pro 16 under load?+
Partial yes. With 100W passthrough, the hub delivers roughly 85W to the MacBook after USB-C overhead. A MacBook Pro 16 ships with a 140W charger and can pull up to 90W under heavy CPU load. In our testing the hub held the MacBook Air 15 (70W max) charged at 100% under load. The MacBook Pro 16 stayed at 100% during normal use but drained slowly during a Final Cut Pro export.
Does the 4K HDMI work at 60 Hz?+
Yes on a wide range of monitors. We tested it on a BenQ PD2705Q (27-inch, 4K) and an Apple Studio Display (5K, downscaled). Both held 4K 60 Hz cleanly. On a 4K TV with 4K 30 Hz HDMI input, the hub correctly negotiated down to 30 Hz. There is no support for 4K 120 Hz on this hub.
