The 4 in 1 Retractable USB C Charger is one of those rare gadgets that actually solves a real problem: the drawer (or bag pocket) full of tangled cables you never want to deal with at an airport gate or a coffee shop. Four devices, one charger, no loose cables to lose. That pitch sold me, and after looking closely at what this thing actually delivers, I think it holds up.
It sits in a price range where chargers are usually either underpowered or poorly built. This one leans on GaN6 technology and a 40W total output to push past those expectations. Here is what you need to know before buying.
What You Actually Get Out of the Box
The package is simple: one charger block and a user manual. The charger itself is white, compact, and built around a foldable plug design that keeps the prongs tucked away when not in use. That detail matters more than it sounds. Foldable prongs mean the charger slides into a bag pocket without snagging or scratching anything around it.
The four charging options are laid out cleanly. You get two built-in retractable USB-C cables that pull out when you need them and snap back when you do not. Alongside those, there is a QC 18W USB-A port and a PD 20W USB-C port. So you can run two devices off the retractable cables and two more off the fixed ports, all at the same time.
The full listing title for exact reference: 4 in 1 Retractable USB C Charger, 40W Retractable Phone Charger Wall Plug.
GaN6 Technology: Does It Actually Matter?
Yes, and here is the short version of why. Traditional chargers use silicon-based components that generate more heat as they push more power. GaN (gallium nitride) chips run more efficiently, which means less wasted energy and a cooler charger body during use. GaN6 is the latest generation of that technology, and the result is a charger that can push 40W total without turning into a small space heater on your wall.
The built-in protections back this up practically: overcharge, overcurrent, overvoltage, and short-circuit protection are all listed. That covers the failure modes that actually kill devices over time. The certifications, UL, CE, FCC, and RoHS, are not just marketing checkboxes. They mean the charger has passed independent safety testing, which matters when you are leaving it plugged in overnight.
Charging Speed: Real Numbers
The claim that stands out most is the 30-minute benchmark. According to the product data, this charger can take an iPhone 17, 16, or 15 (and Galaxy S23/S22 Pro Max) from 15% to 65% battery in 30 minutes. That is a meaningful real-world number because it maps to the situations where you actually need fast charging: a short layover, a quick stop before heading out, a lunch break.
The comparison to a 5W charger is framed as significantly faster. A 5W charger is the old standard brick that used to ship with basic phones. Comparing to that sets a low bar, but the underlying point is solid: 40W PD charging is dramatically faster than what most people still have sitting in a drawer at home.
The total output is 40W, split across all four ports. When you run all four simultaneously, power is distributed across the devices, so peak speeds will be lower per device than if you are charging one thing solo. That is a normal trade-off for any multi-port charger, and worth keeping in mind if you need maximum speed for one specific device.
Who This Charger Is Built For
I keep coming back to the travel use case because it is where this charger makes the most sense. If you regularly pack a phone, wireless earbuds, a tablet, and a second phone (or a partner’s phone), this charger replaces four separate cables and potentially multiple wall adapters. That is real bag space and real weight saved.
It also works well for a desk setup at home or in an office. The retractable cables stay out of the way when not in use, which is a small but genuine quality-of-life improvement if you are someone who hates cable clutter on a desk.
Compatibility is broad: iPhone 17/16/15/14/13, Samsung Galaxy S26/S25/S24/S23, Google Pixel 9/8/7/6/5, Nintendo Switch, and other USB-C devices. If you are still on a Micro-USB device, this will not help you. But for anyone in a mostly USB-C household, coverage is solid.
Practical Trade-Offs to Know
The retractable cable length is not specified in the product data, and that is worth flagging. If your wall outlet is awkwardly positioned relative to a nightstand or desk, a short cable could be a friction point. Retractable cables are almost always shorter than standard cables by design, so set expectations accordingly before you buy.
The charger is US Standard socket only, so international travelers will need an adapter for non-US outlets. The 240V input voltage means the charger itself can handle international power, but the physical plug is US-style.
Running all four ports at once does distribute the 40W across devices, so if you need the fastest possible charge for a single device, plug just that device in alone and let it pull the full available wattage. Not a flaw, just how physics works with shared power budgets.
Build Quality and Everyday Feel
The white finish is clean and neutral, which fits most setups without looking out of place. The foldable prong mechanism and retractable cables are the moving parts that take the most wear over time, and how those hold up over months of daily use is something only long-term owners can confirm. Early real-world sentiment suggests the charger is meeting expectations. The Amazon’s Choice badge adds another signal that the charger is meeting baseline expectations at this price point.
The Value Proposition
For what you get, this charger sits in a strong value position. A single GaN wall charger with one USB-C PD port often runs in a similar range on its own. Getting two additional retractable cables and a QC USB-A port on top of that, with GaN6 efficiency and safety certifications included, is a solid package.
If you are someone who has been carrying a tangle of separate cables and chargers, this 4 in 1 Retractable USB C Charger is worth a look. It is not trying to do anything exotic. It just consolidates what you already need into a smaller, smarter package.

Frequently asked questions
Can the 4 in 1 Retractable USB C Charger charge an iPhone and Android phone at the same time?
Yes. The charger supports up to 4 devices simultaneously across its two retractable USB-C cables, a QC 18W USB-A port, and a PD 20W USB-C port. You can mix iPhone, Android, and other USB-C devices without any compatibility issues.
How fast does it charge an iPhone 15 or 16?
According to the product data, it can charge an iPhone 15 or 16 from 15% to 65% in 30 minutes. That applies when using the PD 20W port or a retractable cable with a compatible device.
Is this charger safe to leave plugged in overnight?
The charger includes built-in overcharge, overcurrent, overvoltage, and short-circuit protection. It also carries UL, CE, FCC, and RoHS certifications, which are independent safety standards. Those protections are specifically designed to handle overnight and unattended charging scenarios.
Does it work outside the United States?
The charger supports 240V input, so it can handle international power systems electrically. However, the physical plug is US Standard, so you would need a plug adapter for non-US outlets. It does not come with one.
What devices are compatible with this charger?
Compatibility includes iPhone 17/16/15/14/13, Samsung Galaxy S26/S25/S24/S23, Google Pixel 9/8/7/6/5, Nintendo Switch, and other USB-C devices. It does not support Micro-USB devices without a separate adapter.
