A good USB-C hub turns one port on a MacBook Air or iPad into the connections people still use every day: HDMI, USB-A, USB-C data, charging, SD cards, microSD cards and wired Ethernet.
The Plugable USBC-7IN1 is the best overall hub under $40 because it combines 4K 60Hz HDMI, three USB-A ports, SD and microSD readers and up to 100W pass-through charging. The UGREEN 7-in-1 is better when Gigabit Ethernet matters, while the Anker 332 is the best simple everyday option for users who do not need card readers or Ethernet.
Compatibility and price warning: These hubs are designed for MacBook Air models and iPads with USB-C or Thunderbolt ports. They do not plug directly into older Lightning iPads. Advertised “100W charging” normally means maximum power input; the hub uses some power itself, and a compatible charger is usually sold separately.
Quick Answer
Choose the Plugable USBC-7IN1 when you want the most useful mix of ports for work, travel and photo transfers. Choose the UGREEN 7-in-1 when a wired Ethernet connection is important. Choose the Plugable USBC-4IN1 when 4K 60Hz video and 10Gbps SSD transfers matter more than card readers.

Detailed Reviews
Plugable USBC-7IN1 — Best Overall
The most useful combination of display, storage and charging ports under $40Verdict: The Plugable USBC-7IN1 is the best all-round choice because it covers the ports most MacBook Air and iPad users actually need without wasting space on outdated connections.
Its HDMI port supports up to 4K at 60Hz, which produces smoother cursor movement and scrolling than the 4K 30Hz output found on many budget hubs. That difference is noticeable when the hub is used as part of a daily desk setup rather than only for occasional presentations.
Three USB-A 3.0 ports provide room for a keyboard, mouse receiver, flash drive, audio interface or external storage. The SD and microSD slots are especially useful for photographers, drone users, action-camera owners and anyone transferring media without a separate reader.
The Power Delivery port accepts up to 100W and can provide up to 92W to the connected host after accounting for hub operation. That is more than enough for normal MacBook Air charging when paired with a suitable charger and cable.
Plugable also lists a two-year warranty and lifetime technical support. That support is valuable because hub problems are often caused by a specific display, cable, charger or host combination rather than the hub alone.
Why It Ranks First
- 4K 60Hz HDMI is uncommon at this price.
- Three USB-A ports handle several legacy accessories.
- SD and microSD readers eliminate a separate adapter.
- Up to 92W host charging provides useful power headroom.
- Two-year warranty and lifetime support reduce purchase risk.
Watch out: There is no Ethernet port and no downstream USB-C data port. Choose another model if wired networking or USB-C accessories are essential.
Pros
- Excellent port selection
- 4K 60Hz HDMI output
- Three USB-A ports
- SD and microSD readers
- Strong warranty and support
Cons
- No Ethernet
- No USB-C data output
- Charger is not included
UGREEN 7-in-1 USB-C Hub — Best With Ethernet
A complete desk hub with 4K 60Hz HDMI, card readers and Gigabit networkingVerdict: Choose the UGREEN 7-in-1 when you want one inexpensive hub to handle an external display, wired internet, accessories, charging and camera cards.
Gigabit Ethernet is the feature that separates this hub from the top pick. A wired connection can provide more consistent performance than crowded Wi-Fi in offices, hotels, dorms and homes with weak wireless coverage.
The HDMI port supports up to 4K 60Hz with a compatible host, display and cable. SD and microSD slots cover common camera and removable-storage formats, while two USB-A data ports provide connections for older accessories.
This port selection makes the UGREEN especially useful as a low-cost desktop hub for a MacBook Air. It is also practical with a compatible USB-C iPad when the user needs Ethernet, HDMI or removable storage.
The researched sale price is attractive, and its regular official price was also listed below $40. Marketplace pricing and exact model numbers can still change, so compare the listing image and port layout before adding an affiliate link.
Watch out: The Ethernet port and HDMI output share the hub’s available bandwidth and power with other connected devices. Heavy simultaneous use can create more heat and reduce peak transfer performance.
Pros
- Gigabit Ethernet
- 4K 60Hz HDMI
- SD and microSD slots
- Useful charging support
- Strong value for seven ports
Cons
- Only two USB-A data ports
- Sale price can change
- No downstream USB-C data port
Anker 341 7-in-1 USB-C Hub — Best for Photos and Everyday Accessories
A familiar-brand option with card readers, USB-A, USB-C data and chargingVerdict: The Anker 341 is a dependable choice for users who want card readers and a mix of USB-A and USB-C connections from a widely recognized accessory brand.
The two 5Gbps USB-A ports are suitable for external drives, flash storage and accessories. A separate USB-C data port is included, but it operates at USB 2.0-class speed rather than the 5Gbps or 10Gbps speed some buyers may expect from the connector shape.
Both SD and microSD slots are included, making the hub useful for photographers and content creators. The HDMI port supports up to 4K 30Hz, which is adequate for movies, presentations and static office work but less fluid than 4K 60Hz for a full-time monitor.
The hub accepts up to 100W input and reserves approximately 15W for its own operation, allowing up to 85W to reach the connected laptop. A charger is not included.
Anker’s published compatibility information focuses heavily on MacBook models. Standard hub functions may also work with compatible USB-C iPads, but buyers should verify the exact iPad model and intended HDMI or storage use.
Watch out: The downstream USB-C data port is limited to 480Mbps. Do not buy this hub specifically for high-speed USB-C SSD transfers.
Pros
- SD and microSD readers
- Two 5Gbps USB-A ports
- Separate USB-C data port
- Up to 85W host charging
- Recognized accessory brand
Cons
- HDMI is limited to 4K 30Hz
- USB-C data is only 480Mbps

Plugable USBC-4IN1 — Best for 4K 60Hz and Fast External SSDs
Fewer ports, but better speed and display specifications than most budget hubsVerdict: The Plugable USBC-4IN1 is the better choice when display smoothness and fast storage matter more than having seven or eight different ports.
The HDMI 2.0 connection supports up to 4K 60Hz and HDR with compatible hardware. This makes the hub more suitable for a permanent monitor than inexpensive 4K 30Hz adapters.
One USB-A port supports data transfers up to 10Gbps, making it a useful match for a fast external SSD or high-speed card reader. The second USB-A port is limited to 480Mbps and is better reserved for a mouse, keyboard, printer or receiver.
The USB-C combo port can serve as a Power Delivery input or as a 10Gbps data connection, depending on the connected device. It should not be treated as two separate ports, and its exact behavior should be considered when planning a setup.
There are no built-in card readers or Ethernet. Buyers who need those features will get more convenience from the Plugable 7-in-1 or UGREEN 7-in-1.
Watch out: The USB-C combo port may be used for charging or USB-C data depending on the setup. Make sure the remaining ports are enough when the hub is connected to power.
Pros
- 4K 60Hz HDMI with HDR
- 10Gbps USB-A data
- 10Gbps USB-C data option
- 100W-class charging support
- Two-year warranty
Cons
- No card readers

UGREEN Revodok 6-in-1 — Best Budget Hub With Ethernet
A low-cost desktop option with three USB-A ports and wired networkingVerdict: The Revodok 6-in-1 provides exceptional value when you need Ethernet and several USB-A ports but do not need memory-card readers.
The hub includes three 5Gbps USB-A ports, giving it more room for older accessories than many similarly priced models. That layout works well for a keyboard, mouse receiver, webcam, flash drive or external storage.
Its Gigabit Ethernet port is useful for stable video calls, large downloads and work environments where Wi-Fi performance is inconsistent. The HDMI connection reaches up to 4K 30Hz and does not support HDR according to UGREEN.
The charging port accepts up to 100W and can provide up to approximately 85W to the host, with power reserved for hub operation. That USB-C port is charging-only and does not support data or video.
UGREEN explicitly lists compatibility with Apple-silicon Macs and iPad. The exact functions still depend on the host device, operating system and whether the USB-C port supports video output.
Watch out: There are no SD or microSD slots, and the HDMI connection is limited to 4K 30Hz. The USB-C port is for power input only.
Pros
- Very competitive price
- Three 5Gbps USB-A ports
- Gigabit Ethernet
- Up to 85W host charging
- Official iPad compatibility listed
Cons
- 4K output is limited to 30Hz
- No memory-card readers
- USB-C port is charging-only
Anker 332 5-in-1 USB-C Hub — Best Simple Everyday Hub
A compact adapter with HDMI, three data ports and chargingVerdict: The Anker 332 is the best straightforward option when you need HDMI, fast USB data and charging but have no use for Ethernet or card readers.
Two USB-A ports and one downstream USB-C data port all support speeds up to 5Gbps. That makes the hub more flexible than models with several USB-A 2.0 connections intended only for keyboards and mice.
The HDMI port reaches up to 4K 30Hz. This is sufficient for presentations, streaming and a secondary office display, although users spending an entire workday on an external 4K monitor may prefer the smoother 60Hz output of the Plugable alternatives.
The Power Delivery input supports up to 100W, with up to approximately 85W available to the host after hub operation. The hub does not include a wall charger.
Its main strength is simplicity. There are fewer ports to manage, the body is compact, and every data port is fast enough for common flash drives and portable storage.
Watch out: There is no Ethernet and no SD or microSD reader. Adding separate adapters later may cost more than buying a seven-port hub now.
Pros
- Three 5Gbps data ports
- USB-A and USB-C accessories
- Useful charging support
- Compact for travel
- Reasonable regular price
Cons
- No card readers
- No Ethernet
- 4K HDMI is limited to 30Hz
Satechi 4-Port USB-C Hub With Power Delivery — Best for USB-C Accessories
Four modern USB-C connections for SSDs, card readers and other data devicesVerdict: This Satechi hub is the right choice for users who have moved away from USB-A and need several fast USB-C data connections rather than HDMI, Ethernet or card readers.
All four downstream connections use USB-C. One port supports up to 100W Power Delivery input and 10Gbps data, while the remaining three ports support data transfers up to 10Gbps.
This layout is useful for USB-C SSDs, card readers, audio interfaces and other modern accessories. It is especially relevant to iPad users because many tablet-sized hubs still provide mostly USB-A connections.
Satechi lists compatibility with macOS and iPadOS. The aluminum enclosure, braided host cable and reinforced connector also make it a more premium physical design than many inexpensive plastic hubs.
None of the downstream ports support video output. The three data-only ports also do not charge connected devices. Buyers needing HDMI should choose another product in this guide.
Watch out: This is not a display hub. The downstream USB-C ports do not output HDMI or DisplayPort video, and only one port handles Power Delivery input.
Pros
- Four USB-C connections
- Up to 10Gbps data
- 100W Power Delivery support
- Explicit iPadOS compatibility
- Compact aluminum construction
Cons
- No HDMI or video output
- No USB-A ports
- No card reader or Ethernet
MacBook Air and iPad Compatibility Guide
MacBook Air
USB-C and Thunderbolt-equipped MacBook Air models can use standard USB-C hubs for HDMI, charging, storage, card readers and Ethernet. Display resolution and the maximum number of external displays depend on the exact MacBook Air model.
USB-C iPad
Compatible iPad Pro, iPad Air, iPad mini and standard iPad models with USB-C can use hubs for displays, storage, keyboards, Ethernet and charging. Available features depend on the iPad model and iPadOS.
Lightning iPad
These hubs do not plug directly into a Lightning connector. A Lightning-to-USB camera or display adapter may support limited accessories, but it does not turn an older iPad into a full USB-C host.
Before Buying, Check These Four Details
- Confirm that the device has a USB-C or Thunderbolt port.
- Check whether the host port supports video output.
- Confirm the external-display resolution supported by the exact MacBook Air or iPad model.
- Use a charger and USB-C cable with enough wattage for the device and connected accessories.
HDMI and External-Display Limits
A USB-C hub cannot create display support that the MacBook Air or iPad does not already provide. The hub carries the video signal supported by the host device; it does not replace the device’s graphics hardware.
Some MacBook Air models support one external display, while newer models can support additional displays under specific resolution and refresh-rate limits. A hub does not increase the maximum number supported by the Mac.
On iPad, HDMI output also varies by model. Several recent iPad Pro, iPad Air, iPad mini and standard iPad models can output up to 4K 60Hz with a suitable HDMI 2.0 adapter. Older USB-C iPads may be limited to 4K 30Hz.
Video mirroring and a fully extended desktop are not the same thing. Some iPads and apps mirror the internal screen, while supported Stage Manager configurations can use a separate external workspace.
Mac dual-monitor warning: Cheap hubs advertising two HDMI ports do not automatically provide two independent extended desktops on macOS. Many rely on MST, which macOS may mirror rather than extend. DisplayLink-based docks require software and normally cost more than $40.
How to Choose a USB-C Hub Under $40
1List the Ports You Actually Need
Choose HDMI for a monitor, Ethernet for stable networking, card readers for cameras and enough USB data ports for your regular accessories.
2Choose 4K 60Hz for Daily Monitor Use
A 4K 30Hz connection can look acceptable for video and presentations, but 60Hz feels smoother for scrolling, cursor movement and general productivity.
3Do Not Confuse Input With Output
A hub marked “100W PD” may accept 100W but send 85W or 92W to the host after reserving power for its internal electronics.
4Check Whether a Charger Is Included
Most hubs under $40 do not include a wall charger. Use the MacBook or iPad charger, or buy a suitable USB-C Power Delivery charger separately.
5Match Data Speed to the Device
USB 2.0 at 480Mbps is fine for keyboards and mice. Use 5Gbps or 10Gbps ports for external SSDs, large backups and high-speed card readers.
6Read the USB-C Port Description
A USB-C-shaped port may support charging only, data only or both. It does not automatically support video output.
7Use Ethernet for Stability
Gigabit Ethernet is useful for large downloads, cloud backups, online meetings and locations with congested or unreliable Wi-Fi.
8Choose the Correct Card Slots
Photographers often need full-size SD, while drones, dash cams and action cameras commonly use microSD. Some hubs include both.
9Consider Cable Length and Port Strain
A short attached cable is compact, but a heavy hub can pull on an iPad port. Place the hub on the desk rather than letting it hang.
10Plan for Power-Hungry Accessories
Several external hard drives, audio interfaces or capture devices may exceed the power available from an unpowered hub. Connect a charger when needed.
Common USB-C Hub Problems and Quick Fixes
The External Display Is Not Detected
Confirm that the host USB-C port supports video, reconnect the hub, select the correct monitor input and test a different HDMI cable.
The MacBook Charges Slowly
Use a higher-wattage charger and cable. Remember that the hub reserves power, so the laptop receives less than the advertised PD input.
An External Drive Disconnects
Connect power to the hub, test one drive at a time and avoid running several bus-powered storage devices from a single inexpensive hub.
The iPad Says the Accessory Uses Too Much Power
Connect a USB-C charger to the hub’s Power Delivery port or use a separately powered accessory.
Ethernet Is Slower Than Expected
Use a Cat 5e or better cable, check the router or switch port and confirm that other hub activity is not saturating the shared USB connection.
The Hub Feels Warm
Moderate warmth is common during charging, HDMI output and large transfers. Disconnect it if it becomes unusually hot, smells abnormal or repeatedly loses connection.
What to Avoid
USB-C Hub Buying Mistakes
- Buying only by port count: ten slow or duplicated ports may be less useful than four well-chosen connections.
- Assuming every USB-C port is identical: some support only charging, while others support data or video.
- Expecting 100W at the MacBook: the hub keeps part of the input power for operation.
- Ignoring 30Hz vs 60Hz: 4K 30Hz may feel noticeably less smooth during desktop work.
- Expecting dual extended monitors: inexpensive MST hubs often mirror displays on macOS.
- Using a Lightning iPad: these hubs require a USB-C or Thunderbolt host connection.
- Connecting several unpowered hard drives: the host port may not provide enough power.
- Letting the hub hang from an iPad: the weight can strain the tablet’s USB-C port.
- Using a low-quality HDMI cable: the cable can prevent stable 4K 60Hz output.
- Choosing a case-blocking direct-fit hub: hubs that attach flush to an iPad may not fit over protective cases.

Frequently Asked Questions
What is the best USB-C hub under $40 for MacBook Air and iPad?
The Plugable USBC-7IN1 is the best overall choice because it combines 4K 60Hz HDMI, three USB-A ports, SD and microSD readers and up to 100W pass-through charging.
Will any USB-C hub work with an iPad?
No. The iPad needs a USB-C or Thunderbolt port, and individual functions such as HDMI output depend on the exact iPad model, iPadOS version and connected accessory.
Can I use these hubs with a Lightning iPad?
Not directly. These hubs use a USB-C host connector. Older Lightning iPads require a compatible Lightning adapter and usually provide more limited accessory support.
Do USB-C hubs charge the MacBook Air?
Models with a Power Delivery input can pass power from a compatible USB-C charger to the MacBook Air. The charger is normally not included.
Does a 100W USB-C hub deliver 100W to the laptop?
Usually not. The 100W figure commonly describes maximum input. The hub reserves power for its electronics, so host output may be approximately 85W or 92W.
Is 4K 30Hz good enough?
It is adequate for presentations, movies and occasional use. A 4K 60Hz connection feels smoother for cursor movement, scrolling and full-time desktop work.
Can a cheap USB-C hub run two external monitors on a MacBook Air?
Not necessarily. Display support depends on the MacBook Air model, and many inexpensive dual-HDMI hubs use MST, which macOS may mirror instead of providing two independent desktops.
Will a USB-C hub increase the MacBook Air display limit?
No. A standard hub does not increase the number of external displays supported by the Mac. DisplayLink docks may add software-driven displays but require drivers and usually cost more.
Can I connect an external SSD to an iPad through a hub?
Yes, on compatible USB-C iPads. A fast 5Gbps or 10Gbps port is preferable, and power may need to be connected if the SSD draws more energy than the iPad can provide.
Why does my iPad say the accessory requires too much power?
The connected drive or accessory may need more power than the iPad supplies. Connect a compatible charger to the hub’s Power Delivery port.
Do USB-C hubs slow down external drives?
They can. Performance is limited by the hub port speed, the host connection, the drive and other devices sharing the same USB bandwidth.
Is Ethernet useful on an iPad?
Yes. A compatible USB-C Ethernet hub can provide a stable wired network connection for downloads, cloud work, streaming and video calls.
Can the SD and microSD slots be used at the same time?
It depends on the hub controller. Some hubs allow simultaneous access, while others read only one card at a time. Check the exact product documentation.
Is it normal for a USB-C hub to become warm?
Moderate warmth is normal during charging, HDMI output and file transfers. Stop using the hub if it becomes unusually hot, smells abnormal or repeatedly disconnects.
