A passive Y cable is not a substitute for a hub, and a two-A-plug cable must not be used to draw extra power from two USB ports. For several low-power accessories, a bus-powered hub may be suitable; for multiple or higher-power devices, choose a powered hub and check its specifications.
What people mean by a “USB splitter”
The phrase can describe two different things:
- A USB hub: connects to one host port and provides multiple downstream ports. This is the normal way to connect several USB peripherals through one port.
- A passive splitter or Y cable: divides a cable connection without acting as a proper multiport hub. In particular, USB-IF prohibits using a two-A-plug Y cable on a USB peripheral to draw extra power. A peripheral that needs more power than its applicable USB specification permits must be self-powered. See USB-IF’s compliance policies.
So the useful safety question is not whether every device called a “splitter” is safe; it is whether the accessory is a suitable hub, correctly powered and compatible with the connected equipment.

How hub power affects safety and reliability
Bus-powered hubs
A bus-powered hub gets its power from the host connection and shares that available supply among the attached devices. It can suit low-power accessories such as a keyboard or mouse. If too many devices are connected, or a device needs more power than the hub can provide, devices may not work correctly or may not be recognized. Dell describes these limitations in its USB port guidance.
Powered hubs
A powered hub uses an external AC adapter rather than relying entirely on the host port. Dell recommends this type for multiple peripherals or devices with higher power needs. Check the hub’s own power specifications: an adapter does not mean the hub can supply unlimited power or meet every device’s requirements.

USB current limits: what the figures do and do not mean
USB-IF’s compliance policy gives a maximum of 500 mA for a peripheral on a standard USB 2.0 downstream port and 900 mA for a peripheral on a standard USB 3.0 downstream port. Those figures apply to the specified standard ports; they are not universal limits for all USB-C ports, charging arrangements, or USB Power Delivery systems. A device that requires more power than the applicable specification allows must be self-powered. The figures and qualification are stated in USB-IF’s compliance policy.
USB-C connector shape alone does not tell you how much current a port can provide. Under the USB Type-C specification, a host or downstream hub port advertises an available current level over the CC pins, and the device must manage its draw to stay within that level, scaling back if the advertised level falls. See the USB Type-C Specification Release 2.0.

- Smart Charging Ports: 2 Extra 5V/2.4A charging ports supporting 2.4A output specially designed for smart charging. Charges most USB charging equipment, regardless of large batteries such as smartphones or tablets, or mini-battery equipment such as smart portable devices, at full speed.
- Faster Speed with USB 3.0: USB 3.0 ports offer transfer speeds of up to 5Gbps, 10 times faster than USB 2.0. This 7-port USB 3.0 data hub can instantly expand 1 USB 3.0 port to 7 USB 3.0 data ports for keyboard, mouse, printer, hard drivers and other USB devices.
- TP-Link Charging technology intelligently identifies connected devices, automatically delivering the smart charge to your smartphones, tablets or devices with a USB charging connector, minimizing charging time.
- Protect Both Your Equipment and Your Data: UH720 has a sophisticated circuit design with multiple overheat, overload, overvoltage and short circuit protections. A built-in surge protector keeps both your devices and your data safe in the data transfer process.
- UH720 supports hot-swap USB ports that can be safely connected and disconnected while the computer is on and running.
USB Power Delivery supports more flexible power delivery and system-level power management, but that does not make every hub a USB PD hub or guarantee it can charge a particular host. Confirm the hub’s explicitly stated capabilities and the host’s requirements in the USB-IF overview of USB Power Delivery.

How to choose a safe, compatible hub
- Identify the devices and their power needs. A few low-power input accessories are a more natural fit for a bus-powered hub; several devices or peripherals with higher power needs point toward a powered hub.
- Check the hub’s power arrangement and specifications. Confirm whether it is bus-powered or uses an external adapter, and that its stated capabilities suit the attached devices.
- Match the host connection and USB features. Check connector compatibility and the USB version supported by both the host and the hub. A slower hub can limit the speed of connected devices even when the host and devices support faster operation, as Dell notes in its USB port guidance.
- Verify charging and data features separately. Do not infer a data rate, charging capability, or USB Power Delivery support from a USB-C connector alone; look for explicit support for the feature you need.
What to do if devices fail to work through a hub
If devices are not recognized or do not work reliably, power may be insufficient for the connected load. Try disconnecting other devices or moving higher-power peripherals to a suitable powered hub. Also check that the hub’s USB version and features match the host and peripherals; a speed limitation may be a compatibility or capability issue rather than a safety problem.
