Compare the ProMaster GaN 65W 3-port charger and the USB-A wall charger on price, ports, and travel practicality. See which one belongs in your camera bag.
Quick answer
Pack the ProMaster GaN USB Charger 3-Port 65 Watt when you need to charge a camera, phone, and accessory from one outlet. Choose the ProMaster USB-A Wall Charger when you want the lowest-cost spare for a single USB-A device.
What the price difference actually buys
The GaN charger lists at USD 28.76 against a USD 39.95 comparison price, while the USB-A wall charger lists at USD 7.56 against USD 10.95. That gap is the clearest trade-off in this comparison: the USB-A unit is a low-cost single-purpose brick, and the GaN unit costs more because it is a three-port charger.
Neither listing supplies wattage per port, cable contents, or foldable-plug details, so treat the port count and price as the reliable differences and verify the rest against the product page before you rely on a specific device.
Why port count matters on location
A multi-port charger for camera gear reduces the number of wall adapters you carry, but only if your devices match its ports. The GaN model is listed as a 3-port USB charger, so it can serve several devices from one outlet; the USB-A wall charger is a single USB-A adapter, which means one device at a time.
If you routinely charge a phone and a camera accessory overnight, the single-port USB-A charger forces you to rotate devices or bring a second adapter. That is the practical cost hidden behind its lower price.
The USB-C question neither listing answers
The GaN product name includes USB, but the supplied catalog facts do not confirm USB-C Power Delivery output. If your camera or phone requires USB-C PD, check the product page for the exact port types and power profile before buying; do not assume a 65-watt rating is delivered on every port.
The USB-A wall charger is clearly a USB-A output, so it suits devices that charge from a USB-A cable. For newer camera bodies or phones that expect USB-C PD, that is a real limitation rather than a minor inconvenience.
Trade-offs to weigh before you pack
- Cost vs. outlet count: The USB-A wall charger costs far less but gives you one USB-A port; the GaN charger costs more and gives you three ports. Count how many devices you charge at once before deciding. If you regularly charge two or more devices overnight, the single-port charger will likely force a second adapter.
- Port type vs. device compatibility: The USB-A charger is a USB-A output. The GaN charger is listed as USB, but the supplied facts do not confirm USB-C PD, so verify port types on the product page if your camera or phone needs USB-C PD.
- Travel bulk vs. backup simplicity: A three-port charger replaces multiple bricks in a camera bag, while a single USB-A wall charger is the simpler low-cost backup. Neither listing confirms cable contents or plug style, so check before relying on it as your only charger.
