When it comes to tech, not much can be achieved without speed & power. Even though battery tech in 2025 is better than ever, you won't want to find yourself with a dead battery and no outlet in sight. Or are you stuck with a charger that's slower than a snail? We've all been there. As battery capacities improve, so does charging tech. I'm excited to show you three incredible charging solutions from CukTech that will improve how you power up your devices in 2025.

We're talking about a beast of a power bank, which is surprisingly small given its incredible capacity, a super-fast Gan 3 100-watt wall charger, and a miniaturised, pocketable 65-watt Gan 3 powerhouse. So, if you are ready to say goodbye to battery anxiety and hello to ultimate charging freedom, Let's get into it.

20000mAh 140W Power Bank

First up, we have the CukTech 15 power bank Ultra. It's a 20,000mAh monster with a whopping 210W combined output. But what might surprise you is how compact this one is. It's roughly the size of a red bull can. And it's also a unique feature I've never seen before. The official model code name on this one is PB200U. Most phones have a battery size of around 5000mah. This means that this power bank can charge your phone from empty to 100% around 4 times. And thanks to its peak 140-watt charging speed on a single USB C port, it can also charge larger devices such as your laptop.

There are 3 ports on board, 2 USB C and a USB A, all of which can be used simultaneously. In this scenario, the combined split output will max at 210 Watts. This could be perfect for charging your laptop, tablet and phone simultaneously, and it does it FAST. I tested this with my Huawei Matebook laptop and it took it from zero to 24% in just 30 minutes and used around 40% of its battery. So this makes the CukTech 15 Ultra perfect for travellers or business trips, also digital nomads, or anyone who needs serious power on the go. Let’s say you got a steam deck or something. Plus, check this out. That unique feature I mentioned.

Now, every power bank can be recharged via cable. Well, this once, of course, can too. But let me know if you've seen one that can do this before… If you plug in a second USB C cable from a wall outlet, the 15 Ultra engages its unique recharging, 'Beast Mode,' and can max out at a 165 Watts recharge speed. This is definitely a stand-out feature, in my opinion. And this one does have a button up front. That allows you to toggle through three modes by pushing and holding for 2 seconds. But something that I love about CukTech power banks is their heads-up displays.

So here you can see exactly how much wattage is being used by each port & the overall percentage of battery reserves left & it even shows recharging speeds and the exact time needed to fully recharge. So, this power bank ticks a lot of boxes. It's great for recharging multiple devices simultaneously, or rapid charging individual devices. It comes with a nice carry pouch and capable cable for maximum speed. It's compact, keeps you visually informed, has specific modes, and is one of the best-looking 20,000mAh I've ever seen. The only downside, if you can call it that, is its weight. Which is a small burden to endure for so much portable power. The price of the CukTech 15 Power Bank Ultra is £89.95 at the time of this video.

GaN 3 100W Wall Socket Charger

Next, we have the game-changer for travel and for at home. The CukTech 100W wall charger is powered by GaN 3 technology, codenamed 2C1A. What is GaN? It stands for Gallium Nitride, and it basically means this charger is smaller, faster, and more efficient than traditional chargers. Just look how compact this thing is! It's like a phone charger we used to get in the box with a phone, but it can output 100W. Which is enough to quickly charge most laptops while still having juice left over to charge your phone. Like the 15 Ultra power bank, It has three ports, so you can free up sockets on a power strip that you might be using or just maximise that single wall outlet.

Plus, it's got 8 different safety features built in to protect you and your devices, as you'd expect. So you rest assured that you won't end up like Marv in Home Alone. So, lots of upsides to a charger like this. If wall sockets are few and far between, you can make the most of a single socket. It's compact, lightweight and easy to travel with. It delivers fast speeds & high power output without risking your devices. Now, the fact that this is harnessing the latest GaN 3 charger tech does mean that it's a little more pricey than regular slow chargers. The price of this one in Europe at the time of this video is 25.99 Euros & it is well worth it. It also ships with a 240W cable in the box.

Tiny 65W GaN 3 Wall Charger

Last but not least, This one is for anyone who likes to travel as light as possible & for anyone who needs a charger that hits optimal phone charging speeds of up to 65W. At the same time, it can still charge bigger devices like a laptop. This one is the CukTech 65 GaN fast charger, codenamed AD653CEU. Like the other two products, it has three ports but a lower 65W peak charging speed due to its smaller stature. But It's still perfect for charging multiple devices.

So it can charge a laptop at 65 watts, or you could charge your phone, your tablet and your earbuds simultaneously, for example, but obviously at slightly slower speeds. That said, most popular phones often cap charging speeds to under 45 watts, so you can still get peak phone charging speeds whilst charging multiple devices. It really depends on what you're charging. But what makes this one great is that it's small enough to just throw it in your bag or even your pocket. So, don't let the size fool you.

Once again, it does have all the safety protocols onboard & just like its bigger brother, it's pretty stylish too. I do like this matted grey & blue version. This one is also available in white. The pros and cons of the CukTechs 65 GaN wall charger are that it's small, lightweight, portable, has multiple ports & it's capable of charging bigger devices at 65 Watts, and it does come with a capable cable in the box. However, if you might frequently need even faster speeds for more power-hungry devices or gaming devices, I'd recommend spending a little more for the 100-watt Cuktech GaN wall charger.

Comparison & Recommendations

Which charger would be right for you? Here's my thoughts on that. If you need maximum power on the go, the 20,000mAh power bank is awesome. You get super-fast charging and recharging speeds thanks to beast mode. The display is quite unique and very useful.

However, if versatility and powerful output are top priorities, the CukTech GaN 100-watt wall charger is the way to go. But if portability is your top priority, you can't beat the compact 65W charger. Ultimately, the best charger depends on your individual needs and device use. Consider how many devices you need to charge at once, how much power those devices require, and whether you prioritise portability or maximum power.

Conclusion

Now, listen, I have checked out other CukTech chargers and power banks here on the channel & I love what they're doing in the charging space. When it comes to speed and power delivery. When shopping around, you should ask the question, " Is it too much to ask for both?" Well, CukTech doesn't think so. That's why I like their products.
