The chargers that come with laptops are often the size of a small brick. A modern 65W GaN charger can power the same laptop from a block barely larger than a matchbox, and it will charge your phone and tablet too. If you travel with a bag full of cables, that is a very welcome upgrade. This guide explains what GaN is, five things to check before you buy, and a comparison of two of the smallest 65W chargers that Android Central recently tested.

What Is a GaN Charger?
GaN stands for gallium nitride, a semiconductor material used in power electronics. Compared with the silicon used in older chargers, GaN handles higher power with less wasted energy as heat. This lets manufacturers shrink the components inside the charger and use a smaller case. Android Central’s author notes that both chargers they highlight are about half the size and under a third of the weight of a regular non-GaN charger.

5 Things to Check Before You Buy
1. Power: is 65W enough?
A 65W charger suits most phones, tablets and many thin laptops. If your laptop needs more power, it may charge slowly or not at all while under load. Check the wattage printed on your laptop’s original charger.
2. Charging standards
Look for USB Power Delivery (PD), the standard that most modern devices use. Some phones also use PPS (Programmable Power Supply), which is common on Samsung phones, and newer PD 3.2 AVS (Adjustable Voltage Supply), which some iPhones and laptops use for faster charging. A charger that supports more profiles is more likely to charge your devices at full speed.
3. Number of ports
Single-port chargers are the smallest, but they can only charge one device at a time. If you want to charge a laptop and phone together, look for a model with two ports and check how it splits the power when both are in use.
4. Plug design
Folding prongs save space in a bag and prevent scratches. Fixed prongs can be bulky and may poke out, especially on some international versions.
5. Heat and safety
Small chargers can get warm. Buy from reputable brands that publish safety certifications, and avoid unknown, ultra-cheap chargers that may not meet safety standards. Use a good-quality USB-C cable rated for the power you need.
Two Standout Tiny 65W Chargers
Android Central’s tests of the smallest 65W GaN chargers highlighted two single-port models. Here is a side-by-side look, with details from their report. Read the full test at Android Central’s smallest 65W GaN chargers.
| Spec | UGREEN Nexode Air 65W | Rolling Square Tiny 65W |
| Price (at the time of the report) | $24, down from $39 retail | $49 |
| Weight | 77 g | 70 g (US prongs), 73 g (EU prongs) |
| Size | Roughly the same as the Rolling Square; exact dimensions not listed | 60.5 mm long, 35 mm high and wide |
| Ports | One USB-C | One USB-C |
| Charging profiles | USB PD 3.0 at 65W, plus PD 3.2 AVS | Standard USB PD 3.0 profiles up to 20V/3.25A (65W), plus PPS |
| Cable included | USB-C to USB-C | Not mentioned |
| Colours | Four | Not mentioned |
| Material | Plastic | Plastic |
UGREEN Nexode Air 65W
- Pros: lowest price of the two; four colour options; AVS support, which the author says speeds charging on the iPhone 17 Pro; switches to trickle charging when left plugged in overnight
- Cons: slightly heavier than the Rolling Square; only one port
Rolling Square Tiny 65W
- Pros: textured sides make it easier to find in a bag and to hold while plugging in; lighter; US prongs fold into the body; PPS support, which the author says works well with Samsung phones
- Cons: about twice the price; EU prongs stick out noticeably; only one port; the claimed cooler operation showed little difference in the author’s side-by-side test
The Android Central author said they would choose the Nexode Air for its price. If you own a Samsung phone and value the textured design, the Rolling Square may be worth the extra cost. Check current prices, because deals change quickly.
Which One Fits Your Devices?
| If you have | Consider |
| An iPhone and a USB-C laptop | A charger with PD 3.2 AVS, such as the UGREEN model, according to the Android Central test |
| A Samsung phone | A charger with PPS, such as the Rolling Square |
| A budget limit | The cheaper model with the features you need |
| A need for two devices at once | A two-port charger, which neither of these is |
| Frequent international travel | A model with folding prongs or swappable plugs, and check that prongs fit your destinations |
Get the Most Out of a Small Charger
- Use a cable rated for your charger’s power
- Charge laptops with the laptop turned off or idle if you want the fastest result
- Do not cover the charger while it works
- Unplug it if it becomes unusually hot
- Keep a short cable for travel and a longer one for desk use
- Protect your battery with good habits; our guide to phone battery habits that matter explains how
Charging speed is only half the story. How you charge affects battery life too, so see our article on phone battery habits that actually matter for evidence-based tips.
Common Mistakes
- Buying on wattage alone without checking compatibility with your phone or laptop
- Using a low-quality cable that limits charging speed
- Assuming a single-port 65W charger can charge two devices
- Buying cheap, uncertified chargers
- Forgetting to compare the total price including the cable and plug adapters
How to Test a Charger at Home
- Plug the charger in with a certified cable and connect your device
- Check the charging speed in the device’s battery menu, which may say fast charging or show wattage
- Feel the charger after 20 minutes; warm is normal, hot is a warning
- Compare charging time against your old charger for the same percentage range
- Test with each device you plan to use, including your laptop and phone
- Keep the receipt so that you can return the charger if it does not work with your devices
Safety and Certification
Chargers sit between your home’s mains supply and your expensive electronics, so quality matters. Look for recognised safety marks in your country, buy from authorised sellers and avoid unbranded chargers sold at suspiciously low prices. If a charger smells strange, buzzes loudly, overheats or shows damage, stop using it immediately.
Packing Tips for Travel
- Carry one compact charger and two short cables for most trips
- Check the voltage range printed on the charger; most modern GaN chargers accept a wide range for international travel
- Bring a plug adapter if your destination uses different sockets
- Keep the charger in an easy-to-reach pocket for security checks
- Label your charger so that it is not left behind in a hotel or airport lounge
When a Bigger Charger Is the Better Choice
A tiny single-port charger is perfect for travel, but at a desk you may prefer a multi-port charger that can power a laptop, phone and earbuds at once. If your laptop needs more than 65W, or you want to run several fast-charging devices together, choose a higher-wattage model with more ports. Size is a bonus, not the only measure of a good charger.
Also think about the cable. A short, well-made USB-C cable keeps the whole setup compact, and a cheap cable can limit speed or fail early.
Frequently Asked Questions
Is a 65W charger safe for my phone?
Yes. Your phone only draws the power it can handle. A certified USB Power Delivery charger negotiates the right voltage and current with the device.
Can a 65W charger charge my laptop?
Often yes, if your laptop needs 65W or less. Laptops that need more power may charge slowly.
Why are GaN chargers smaller?
GaN handles power more efficiently and wastes less energy as heat, so manufacturers can use smaller components.
Do I need a two-port charger?
Only if you want to charge two devices at the same time. Single-port models are smaller and cheaper.
The Bottom Line
A tiny 65W GaN charger can replace several chargers in your bag, as long as it matches your devices. Check the charging standards you need, think about ports and plug design, and buy from a reputable brand. Of the two chargers Android Central tested, the UGREEN Nexode Air looks like the better value, while the Rolling Square Tiny is the pick if you prefer its design and PPS support. Whichever you choose, you will be carrying far less weight.
