Is the OREI M8 Max's USB-C port fast enough to charge a laptop?

No. At 18W, it's enough to fast-charge a phone but well below the 45 to 100W most laptop chargers need. For a laptop, plug its own charging brick into the M8 Max's grounded AC outlet instead of trying to charge through the USB-C port directly.

Does the OREI M8 Max work in the UK and continental Europe?

Yes. It ships with interchangeable plug attachments covering Type G (UK, Ireland) and Type C/E/F (continental Europe), along with attachments for other common regions including Australia, China, and parts of Africa and Asia.

How many devices charge at once on the M8 Max?

Up to six simultaneously: two grounded US AC outlets, three USB-A ports, and one USB-C PD port. Charging all six at once shares the unit's total output, so individual charging speed drops somewhat versus charging just one or two devices.

Is the M8 Max grounded?

Yes, its AC outlets use a grounded 3-prong design, which matters for laptop chargers and other devices that require a ground connection rather than a simple 2-prong plug.

OREI M8 Max Travel Adapter Review: The Best for Charging Several Devices

The OREI World Travel Plug Adapter M8 Max packs 2 US outlets, 3 USB-A ports, and an 18W USB-C PD port into one grounded, interchangeable-head unit for around $22. Full review with charging speed test results.

Most hotel rooms have exactly one accessible outlet, and most travelers carry more than one device that needs charging overnight.

The OREI M8 Max addresses that directly with six total charging points, two grounded AC outlets, three USB-A ports, and an 18W USB-C PD port, all behind interchangeable plug heads covering 150-plus countries.

At around $22, it undercuts the price of some competitors offering fewer ports.

Its main limit is the 18W USB-C port, plenty for a phone but not enough to meaningfully charge a laptop, which should instead use the grounded AC outlets with its own charging brick.

What You Are Buying

The OREI World Travel Plug Adapter M8 Max is a universal travel adapter with interchangeable plug attachments and six built-in charging points across two grounded US-standard AC outlets, three USB-A ports, and one USB-C PD port rated at 18W.

It typically sells for around $20 to $24.

Performance

Plug head fit: attachments for continental Europe, the UK, Australia, and China all seated securely in standard outlets, with a firm lock rather than friction-only fit.

AC outlet fit: both grounded outlets accepted a standard laptop brick and a second grounded device simultaneously without issue.

USB-C charging speed: the 18W PD port charged a compatible phone from 20 percent to 80 percent in a time comparable to that phone's stock charger, a clear step up from plain USB-A ports.

Simultaneous load: charging all six points at once (two AC devices, three USB-A devices, one USB-C device) worked without tripping the internal fuse, though individual charging speeds slowed somewhat under full simultaneous load, as expected with any shared-capacity adapter.

What It Does Well

The sheer number of charging points relative to its compact size is the standout. For a couple or family sharing one hotel outlet, this is the most practical option tested in this category. The grounded AC outlets are a meaningful safety plus over ungrounded competitors.

What Falls Short

The 18W USB-C port, while faster than USB-A, still isn't laptop-charging territory. Travelers hoping to skip carrying their laptop's own brick and just use this adapter's USB-C port directly will be disappointed; the AC outlet with the original brick remains the right approach.

Who Should Buy It

Buy the OREI M8 Max if: you're charging multiple devices overnight, want a grounded design for laptop chargers, and want a faster USB-C port than basic USB-A-only adapters.

Consider alternatives if: you need actual voltage conversion for a single-voltage appliance, in which case the BESTEK is the better fit.
