SpecPicks Verdict

SpecPicks scored BaseNew USB A Type C Male to 3 USB Female Multi-Port OTG Adapter Cable using a rating × review-volume × price-fit model applied to published specs and reviews across the expansion cards category. BaseNew's expansion cards lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for expansion cards of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Will this adapter work with both my old laptop and my new MacBook?

Yes. The plug combines USB-A and USB-C, so it fits USB-A computers as well as USB-C devices like MacBook Pro, MacBook Air, iPad Pro, Dell XPS 13/15, Surface Book 2 and Galaxy S20-S22 phones.

How fast is data transfer through the three ports?

It is a USB 2.0 splitter, with transfer speeds up to 480 Mbps. That is fine for keyboards, mice, controllers and moving files to a flash drive, but slower than USB 3.x for large file copies.

Can I connect a monitor or HDMI display through it?

No. The listing says the adapter supports data transfer only and cannot carry HDMI, video or audio signals. For a display, use a USB-C video adapter or a dock.

Can I charge my phone or laptop through this cable?

Only lightly. The ports share a rated 5V/2A output, and each port drops below 1A when all three charge at once. The adapter does not accept input power, so it cannot pass-through charge the host device.

Do I need to install drivers?

No. The adapter is plug and play. Connect it to your computer, tablet or phone, and supported USB accessories are detected without extra software.
