A 100 W charger does not push 100 W into everything you plug in. Your phone, tablet or laptop tells the charger how much power it can take, and the charger delivers exactly that. What 100 W gives you is headroom: one charger that is enough for a laptop and still charges a phone at the fastest speed the phone allows.
Here is what that means in minutes for the devices people use most, using each maker's own figures, and the two things that decide whether you actually get those speeds: the cable and the charging standard.
How fast Atlas charges the devices you use most
Every figure below is the manufacturer's own claim for fast charging, together with the adapter it requires. Atlas 100W delivers up to 100 W from one USB-C port and supports USB Power Delivery 3.2 with AVS and PPS.
| Device | What the maker requires | Maker's figure |
|---|---|---|
| iPhone 18 Pro, iPhone 18 Pro Max | 60 W or more, USB-PD 3.2 with AVS | up to 50% in about 15 minutes |
| iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max | 40 W or more | up to 50% in about 20 minutes |
| iPhone Air, iPhone 17e | 20 W or more | up to 50% in about 30 minutes |
| Samsung Galaxy S26 Ultra | Samsung's 60 W charger | up to 75% in 30 minutes |
| iPad Pro (M5) | USB-C, 60 W or more | up to 50% in about 30 minutes |
| MacBook Air (2022 and later) | Apple 70 W adapter or higher | up to 50% in about 30 minutes |
| 14-inch MacBook Pro (2021 and later) | Apple 96 W adapter or higher | up to 50% in about 30 minutes |
How to read the table. For the iPhones and the iPad Pro, Apple's requirement is a USB-C adapter of a given wattage, and Atlas meets it. For the iPhone 18 Pro models, Apple also asks for AVS and USB-PD 3.2, which Atlas supports. For MacBooks, Apple quotes its own adapters; Atlas supplies more than the 70 W and 96 W thresholds, so the laptop can draw as much as it takes over USB-C. Samsung's figure is for its own 60 W charger; Atlas supports PPS, the standard Samsung uses for its super-fast charging.
One laptop sits outside the list: the 16-inch MacBook Pro fast charges only with Apple's 140 W adapter. Atlas charges it, but more slowly, and under heavy load it may only hold the battery level.
Why makers quote 50%, not 100%
Fast charging is fastest when the battery is low. As it fills up, the device slows the charge to protect the battery, so the last part takes noticeably longer than the first half. That is why every maker quotes a figure like 50% in 20 minutes. It is also the part that matters day to day: a short stop at the charger before you leave the house.
Above 60 W, the cable decides
A standard USB-C cable is rated for 3 amps, which caps it at 60 W. To carry more, a cable has to be rated for 5 amps and contain a small chip, an e-marker, that tells the charger it is safe to go higher. The phones in the table stay at or below 60 W, so any decent USB-C cable will do for them. For a MacBook Pro, or anything else that takes more than 60 W, use a 100 W cable, like the braided 100 W cable we offer with Atlas.
One port, one device at full speed
Atlas has a single USB-C port. That is how it stays a 35 mm cube and still delivers 100 W, and it means the full power goes to one device at a time. If you charge a laptop and a phone side by side every night, a charger with more ports, like our 67 W three-port charger, fits better. If you want one small charger for whatever needs power right now, one port is the point.
AVS and PPS, in plain words
Older fast chargers jump between a few fixed voltages. PPS and AVS let the charger adjust the voltage in small steps, so the device gets close to exactly what it asks for. Less wasted energy means less heat, and less heat lets the device keep charging fast for longer. Samsung uses PPS for its super-fast charging, and Apple names AVS as a requirement for the fastest iPhone 18 Pro charging.
Frequently asked questions
Can a 100 W charger damage my phone?
No. The phone and the charger agree on the power before charging starts, and the phone never takes more than it is built for. Atlas also has protection against overvoltage, overcurrent, overheating and short circuit.
Does Atlas fast charge the iPhone 17?
Yes. Apple asks for an adapter of 40 W or more for its figure of 50% in about 20 minutes, and Atlas delivers up to 100 W.
Will Atlas charge a MacBook Pro?
Yes. The 14-inch MacBook Pro fast charges with 96 W or more, and Atlas supplies up to 100 W. The 16-inch model charges too, but not at fast-charge speed, which needs Apple's 140 W adapter.
Do I need a special cable?
For phones, no. For anything that takes more than 60 W, use a USB-C cable rated for 5 A and 100 W.
One charger for the desk, the bag and the trip
Atlas 100W comes on its own or together with the braided 100 W cable. Every Adda Collins product has a 2-year warranty, extendable to 5 years when you register it.
