Frequently Asked Questions

At what age is my child ready for a belt-positioning booster like the Tanza?

The Tanza is intended for children who have outgrown their forward-facing harnessed car seat and weigh between 18 and 45 kg (40–100 lbs) while measuring 110 to 145 cm (43–57 in) tall. Most children reach this stage around age four to five, but always check your current car seat's outgrown limits first.

Can I install the Tanza without the UAS connectors?

The Tanza is designed to be used with its rigid UAS connectors for a secure fit. Refer to the product manual for your specific vehicle compatibility and installation guidance.

Is the Tanza allowed on airplanes?

Belt-positioning boosters rely on the vehicle's lap-and-shoulder belt and are generally not certified for aircraft use. Check airline policies before travelling.

Perfect, affordable solution for a second home-office setup
I work from home and occasionally like to office out of a different area of the house, but I didn't want to tear down my entire main rig just to move to another room. I picked this up as a secondary docking station for a more casual monitor setup, and it works perfectly for my needs. Setup & Performance: I have this hooked up to my work laptop and two monitors via HDMI. One thing to keep in mind: you’ll need to provide your own USB-C cable and power brick to juice it up. Just make sure you’re using a high-quality charging block to ensure the dock gets consistent power for all your peripherals. The Value: Compared to the price of a name-brand Dell docking station, the value here is incredible. While the more expensive docks might offer a few extra bells and whistles, this is exactly what I needed without the hefty price tag. Pros: Simple Setup: Very straightforward to get running. Dual Monitor Support: Handles two HDMI monitors with no issues. Compact: Great for a secondary or portable "mini" workstation. Bottom Line: If you’re looking for an easy, inexpensive way to run dual monitors from your laptop in another part of the house, this is the way to go. Great performance for the price!

Works well but pay attention **REVISED**
The device has worked well for me. However potential buyers should note that the 2nd USB C port is reserved for power input from a separately purchased power supply. So the device provides only a single USB C port for attaching devices. I use the device on power from my own computer. So undocking my computer requires some careful steps in the correct sequence: (1) eject all external drives; (2) power down the external display; (3) unplug Anker from computer; (4) remove power from the computer. The device comes at a great price, though, so excellent value. *REVISION* After four months of use, the HDMI port seemed to fail--the monitor was indicating that it was not connected. I wrote to Anker support and received a reply within two hours. The reply told me how to reset the docking station. It worked. Kudoes to Anker Support!

Quality multi display hub
Works as intended, good value for the money and reasonably sized. I am currently running two 4K HDMI monitors on it without an issue. Ready to go out of the box and has a sturdy design, would recommend.

Anker support comes through
Update: Anker support contacted me and provided a new unit. On this one, the video works fine, both via HDMI and DisplayPort. I'm much happier now that the unit, which I do like, works properly. There is still one video-related quirk that can be annoying, though, if you often unplug the external monitor from the hub but leave the hub connected to the computer. When I unplug the external monitor from the hub, the hub doesn't tell the computer that the monitor is no longer connected (the same thing happened with the original faulty unit). Since the external monitor is my primary monitor when connected, this leads to an irritating set of steps ending up with disconnecting the hub. I reported this issue to Anker support and they forwarded it to their engineering group. Initial review: I like the form factor and the many connection options. They all work fine EXCEPT that the video (whether DisplayPort or HDMI) keeps dropping out. The computer (MacBook Pro M1 14" running MacOS 13.0.1) thinks the external monitor is there, but nothing shows on the screen for a few seconds, then it comes back on, then off again. Anker support says to try updating the firmware, but to do that requires a Windows computer with a USB-C port. I do not have access to such a machine, so I'm stuck. Since one of the primary reasons I want a hub is to handle the video, I have to return the unit. This is a real disappointment since I otherwise have been very happy with Anker products.
