UGREEN sells chargers from pocket-size phone adapters to multi-port laptop units. The biggest number is not automatically the best purchase. A 100W charger used only with a 20W phone adds cost and size; a 20W brick cannot replace a laptop adapter.
The short answer: 20W is a clean phone-first choice, 30W adds flexibility for larger phones and tablets, 65W is the practical one-charger option for many ultrabooks, and 100W suits high-power laptops or several devices. Protocol and port allocation still matter.
Four useful power classes
| Class | Best fit | Watch for |
|---|---|---|
| 20W | Supported iPhones and everyday phones | May not maximize faster tablets or Samsung modes |
| 30W | Phones, small tablets, light travel | Some laptops need more |
| 65W | Many USB-C laptops plus phones | Power may split when two ports are used |
| 100W | Laptops and multi-device desks | Requires a high-rated cable and correct top-output port |
For iPhone
Apple says supported models fast-charge with a compatible USB-C adapter, with iPhone 12, iPhone SE (3rd generation) and later requiring at least 20W. A reputable UGREEN 20W adapter is therefore a sensible compact choice. Going to 30W may provide flexibility for another USB-C device, but the phone will draw only what it negotiates.
For Samsung
Samsung’s Super Fast Charging modes depend on USB PD with PPS and vary by phone. Match the charger’s PPS profiles and wattage to the exact Galaxy model. A charger merely displaying “45W” is not enough if the required protocol or cable is missing.
For tablets and laptops
Tablets often benefit from 30W or more. Many thin USB-C laptops are comfortable around 45W to 65W, while larger models may request 100W or beyond. Check the original adapter and manufacturer guidance. Some gaming laptops accept USB-C power only for light use and still need their proprietary adapter for full performance.
Why a 100W multi-port charger may not give 100W everywhere
The headline wattage normally describes the maximum total or one primary USB-C port under a particular configuration. When you connect a second device, the charger follows a power-sharing table. On the UGREEN X564 100W four-port charger, use the highest-output USB-C port for the laptop and verify the allocation shown in the product specification.
Do not forget the cable
High-power charging needs a USB-C cable rated for the job; above 60W, look for the appropriate electronically marked cable. Charging power does not imply fast data. Read our complete USB-C cable guide.
Simple recommendations
- Buy 20W when compact phone charging is the whole job.
- Buy 30W for a phone-plus-tablet travel kit.
- Buy 65W when one USB-C laptop and phone share a bag.
- Buy 100W when you understand the port split and need the headroom.

Frequently asked questions
Can I use a UGREEN 100W charger with an iPhone?
Yes if the charger is standards-compliant and you use the correct cable; the phone negotiates a lower supported level.
Do I need PPS for Samsung?
Compatible Galaxy Super Fast Charging modes use PPS. Confirm the exact phone and charger profiles.
Is 65W enough for a laptop?
For many ultrabooks, yes; larger or gaming laptops may need more or their original adapter.
Why did charging slow when I connected another device?
Multi-port chargers redistribute their total power. The product’s allocation table explains each combination.
How we prepared this guide: We mapped UGREEN charger classes to current Apple, Samsung and USB-C charging requirements. Check the exact model’s port table because similarly named chargers can differ. We do not claim laboratory or long-term hands-on testing unless a page explicitly says so. Product availability and specifications can change, so confirm the current listing before ordering.
