Four-Port USB Charger Pack

This two-pack supplies two 50W wall adapters, each with two USB-C and two USB-A ports for charging phones, tablets, laptops and wearables from one outlet. The compact GaN design folds flat for travel and fits tight power strips without blocking adjacent sockets. It targets users who want a single charger for multiple USB-C and USB-A devices at home or on the road.

Power Distribution Limits

One USB-C port delivers up to 30W at 20V 1.5A while the second USB-C port reaches 20W; USB-A ports also top out at 20W. When two ports are active the combined ceiling is 50W, but with three or four ports the maximum drops to 45W total. The charger negotiates PD 3.0, QC 3.0, PPS and several proprietary protocols, redistributing power briefly whenever a device is added or removed.

Pre-Purchase Checks

Confirm your devices accept 5V, 9V, 15V or 20V profiles up to the per-port limits above; some laptops need more than 30W for full-speed charging. Verify that your wall outlet provides 100–240V AC at 50 or 60 Hz and that the foldable prongs match your local socket type. Ensure the total simultaneous draw of your gear stays within the 45W or 50W multi-port caps to avoid throttling.

Questions about this item

Should I pick the 2-pack or a single unit for home and travel?

The 2-pack gives you two identical 50W 4-port chargers, so one can stay at a desk and the other travel in a bag without swapping cables.

What does the 50W maximum actually deliver to a MacBook or iPad?

One USB-C port holds 30W continuously; adding a second device splits the 50W budget, so a laptop still gets 30W while a phone takes the remaining 20W.

Which fast-charge protocols are supported over the USB-C ports?

The USB-C ports run PD 3.0 and PPS, enabling 30W and 20W steps for iPhone 15/16/17, Pixel 8/9, Galaxy S23/S24/S25 and recent iPad models.
