The ZMI zPower USB-C and Dual USB-A Wall Charger looks like ZMI’s single USB-C port USB-C charger at a glance. But this newer model offers two USB-A ports, besides the same USB PD output. Once you pick it up you’ll find it weighs a bit more, too.
The enclosure is matte white with a smooth and rounded finish. A circulate LED indicates power with a soft, white light. Visible across the room. But not so bright it’ll reflect off the wall in the dark. The USB ports have plenty of space between them. Bringing them closer might have made the charger smaller. But the space allows one to disconnect one cable without disturbing the rest.

USB Power Delivery & Quick Charge 4+ Phones
- Apple iPhone 8/X/XR/XS
- Essential Phone
- Google Pixel
- LG ThinQ/V30
- Samsung Galaxy S8/S9/S10
- Samsung Galaxy Note 8/9
- Xiaomi Mi 8/9
- ZTE Axon Pro 9/10
Using an iPhone 8 for testing we find USB PD phones will fast charge over the USB-C port. iPhones will need to use a USB-C to Lightning cable, not included. And Android phones will need a USB-C to USB-C cable, which is included.
For iPhones the USB-A ports supports Apple 2.4A. An older, but still functional fast charging standard. Older iPhones (4-7) can fast charge using USB-A. Newer iPhones will charge ~15 minutes faster using USB-C.
Quick Charge 3.0 Phones
- Samsung Galaxy
- Xiaomi Mi 5/6
Using a Moto G6 for testing we see Quick Charge will fast charge over either of the USB-A ports. Any QC supporting Android phone with USB-C can use the included USB-C to USB-A cable.
Quick Charge is disabled if both USB-A ports are in use. In which case charging drops to half the speed fast charging provides.
The Nintendo Switch charges at its max rate, up to 18W. It’ll fast charge while you play. Its charge rate while sleeping is also normal. This charger can also power the Switch’s dock. Learn more about charging the Switch.
Using a 13-inch MacBook Pro for testing we can draw up to 42W from this charger. That’s expected, after accounting for efficiency loss.
Different model laptops have different power demands. But in general a 45W charger can support 12-inch, 13-inch, and 14-inch laptops. It can power a larger laptop in a pinch. It will charge while sleeping. But may only extend runtime if used while the larger laptop is active.
Dual USB-A Ports
Each of the USB-A ports is capable of providing up to 18W output. Using Quick Charge 3.0, Samsung Adaptive Fast Charging, Huawei FCP, or Apple 2.4A. You’ll get full output when using only one of the USB-A ports.
When both USB-A ports are in use all fast charging is not available, except for Apple 2.4A. There is also an 18W max output limit between the two ports. Leaving some cables plugged in, even if not connected on the other end, will have the same effect. Most notably Lightning cables for iPhones and iPad.
Connecting to the USB-C port has no impact on the output of the USB-A ports. So you can fast charge two devices at once (USB-C & USB-A). Or fast charge one device (USB-C) and normal charge two other devices (USB-A).
Quick Charge 3.0 Over USB-C
The presence of Quick Charge over USB-C is against USB-C specifications. That said such chargers have been around for years without issue.
Under section 4.8.2 of USB-C specifications a proprietary charging method cannot change the voltage of USB-C output (between 4.40V and 5.25V) in a manner not defined by USB methods. Quick Charge operates at higher than default voltages. And so goes against the specifications. USB Power Delivery is an open source charging method. Created alongside USB-C, it is with specs even though it also increases voltage. The big difference is USB PD uses communication lines to negotiate power transfer. While proprietary methods take over the data lines for their negotiation. They do so because legacy USB connections, such as USB-A, don’t have comm lines.
There is no known risk with running proprietary charging standards over USB-C. Manipulating the data lines does disrupt data transfers. But when plugging into a wall charger or power bank there is no data transfer anyway. A few USB-C focused engineers warn against using any USB-C product against specs. Their concern is unforeseen consequences. And we have seen bad USB-C products in the past. But since the first QC over USB-C charger came out in 2016 we haven’t seen any systemic issues emerge.
I have not run into any issues with these fast charging standards on this or any other charger. But as it is a spec violation I want you to be informed. If you’re a stickler for meeting USB-C specifications this isn’t a good charger for you. If you’re more pragmatic it works fine and has no known issues.
The ZMI zPower USB-C and Dual USB-A Wall Charger makes for a reliable travel charger. Or as a small, multi-port charger around the home or office. Ideal for those who focus on their larger USB-C devices over Quick Charging phones. Regardless of the connections the USB-C output remains available up to 45W. So connecting two phones won’t slow down the charging of your laptop. Or disable the dock of a Nintendo Switch.
The power output compromise is with the USB-A ports. Using a single USB-A port enables Quick Charge, Samsung Adaptive Fast Charging, Huawei FCP, and Apple 2.4A. Using both USB-A ports disables all but Apple 2.4A. And splits the 18W output between the two devices. Still more than enough to charge a pair of phones overnight. And if you need to fast charge two Quick Charge compatible phones you can still do so. Plug one into USB-C (which also supports Quick Charge). And the other into the USB-A port. The only exception is Motorola phones won’t fast charge over USB-C.
For phones it fast charges iPhone 8/X/XR/XS, Samsung Galaxy, and Google Pixel via USB-C. And older iPhones, LG, and Motorola phones via USB-A, provided only one USB-A port is in use.
For the Nintendo Switch it charges in handheld mode as fast as any other option. And can power a docked Switch.
It is bigger and heavier than most 45W USB-C single port chargers. But it makes for a better travel charger than what came with most of your devices. The 45W output is enough for a 13-inch MacBook Pro under most conditions. And unlike Apple’s charger it can charge an iPhone, too.
All at a price less than similarly specced charger. And with a long USB-C to USB-C cable included.

The ZMI zPower USB-C and Dual USB-A Wall Charger should be among your finalizes for a travel charger. Especially if you carry a Nintendo Switch (with or without dock) and/or a 12 to 14-inch laptop. The ability to charge your larger devices along with your phone is essential for a lighter load on the road.

- Need to charge 2-3 devices at a time, either at home, work, or while away
- Are looking for a budget friendly, multi-port charger

Don’t buy if you:
