What is a portable charger?

A portable charger, also known as a Power Bank, is a compact charging solution that stores energy for when you need it most. Think of it as your phone’s backup plan. No wall charger in sight? No worries. Just plug your device into a Power Bank and power up on the spot.

Most portable chargers are powered via a USB-C cable, USB-A, or micro-USB connector. Once charged up, they can top up your phone, tablet, earbuds, Apple Watch, or even your laptop — depending on the model and its battery capacity. Some even offer wireless charging for cable-free convenience.

Portable Power Banks come in all shapes and sizes, from sleek mini chargers that fit in your pocket to high-capacity beasts with multiple output ports. Many feature USB-A and USB-C ports, while others include built-in cables or magnetic compatibility for MagSafe-enabled iPhones and Samsung Galaxy devices.

Why lightweight portable chargers are a must-have

If you’ve ever carried a bulky Power Bank all day just to charge your phone once, you already know the pain. Weight matters. Size matters. And when you’re on the move, every gram in your bag counts. That’s where lightweight portable chargers come in.

Here’s why they’re must-haves:

They won’t weigh you down: Perfect for travel, city commutes, hikes, or working remotely — anywhere that space and weight matter.

They’re built for busy lives: Great for digital nomads, students, commuters, hikers, gym-goers, and festival fans.

Mini but mighty: Most lightweight options pack serious power with up to 10K mAh capacity. Some models even support fast charging.

Loaded with features: Different models of Power Banks include USB-C ports, USB-A ports, dual connectors, built-in charging cables, and magnetic wireless charging for MagSafe-compatible devices.

Charge multiple devices: Heaps of multi port options that let you charge multiple devices at once, from smartphones to AirPods, smartwatches, and even tablets and iPads.

They fit anywhere: Pop one in your pocket, handbag, or clip it to your keys. They’re made to move with you.

Our top picks for lightweight charging on the go

With so many options out there, it can be tricky to know which Power Bank actually fits your lifestyle. That’s why we’ve rounded up our lightest, sleekest, and most practical chargers that keep your devices juiced without weighing you down. Here are our top picks for everyday charging on the move.

1. Thumboost Power Bank 5K + USB-C Cable Combo

This one’s tiny but mighty. We’re talking 112 grams of lightweight magic with a 5,000 mAh capacity. It’s perfect for topping up your phone while commuting or smashing out steps on your walk. It comes with a semi-integrated silicone USB-C cable that wraps neatly around the Power Bank, so you’re never left searching for cords. Dual USB-C ports let you charge and recharge with ease — it’s fast, too, thanks to 20W Power Delivery.

2. Prime Power Bank 10K

Small in size, big on output. The Prime 10,000 mAh Power Bank is built for fast charging with 20W output, and supports both USB-A and USB-C ports. Despite its solid capacity, it’s just 177 grams and slips easily into any bag or jacket pocket.

3. MagSlim Magnetic Wireless Power Bank 5K

Wireless, magnetic, and feather-light at 112 grams. The MagSlim 5K offers 10W wireless charging with a strong MagSafe-compatible magnetic snap. Great for iPhone 12 and up, it keeps your phone powered without the clutter of cables. You’ll barely notice it’s in your bag.

4. MagSlim Magnetic Wireless Power Bank 10K

Love the MagSlim 5K but want more juice? This 10,000mAh version still delivers wireless charging (10W), but also gives you up to 2 full charges wired or 1.5 phone charges wirelessly (based on iPhone 15). It’s just 189 grams and carry-on approved, making it ideal for longer days out or weekends away.

5. ChargeUp Boost 4th Generation Power Bank 5K

This one’s all about value. Lightweight (127 grams), compact, and great for topping up phones, earbuds, and other small devices. It’s got dual charging ports (USB-C & USB-A), so you can charge two devices at once. Bonus: $3 from each pink edition goes to the McGrath Foundation.

6. ChargeUp Reserve 3rd Generation Power Bank 10K

With 20W fast charging and the ability to charge up to three devices at once, this pocket-sized champ punches well above its weight. It’s got two USB-C ports and one USB-A, all wrapped up in a slim 193-gram design. Ideal for busy days where you’re juggling your phone, earbuds, and more.

Lightweight power for off-grid adventures

If you’re heading off the grid but still want to keep your phone, earbuds, or portable power stations topped up, solar power is your new best mate. Cygnett’s Roam 36W Slim Foldable Solar Panel is a total game changer for campers, hikers, and van-lifers.

Here’s why it’s ideal for off-grid charging:

1. Fast 36W USB-C charging: Power up phones, tablets, and portable chargers directly from the sun

2. Four ultra-durable ETFE panels: Built to handle harsh Aussie conditions

3. Folds flat for easy packing: Compact and lightweight (just 870 grams), it fits neatly in your daypack

4. USB-C to USB-A converter included: Charge a wider range of devices with no fuss

Whether you’re camping in the bush or working remote in nature, the Roam Foldable Solar Panel keeps your devices powered up without needing a single wall socket. Lightweight and foldable, it’s perfect for anyone who wants to stay connected in the great outdoors. 

Remember to keep your Power Bank out of direct sunlight while charging. Power Banks generate heat when charging, so always keep them in a cool, well-ventilated, and shaded area.

Compact charging for footy fanatics

Footy season waits for no one. And whether you’re watching from the stands or glued to your screen on the go, the last thing you want is a flat phone before the final siren. That’s where Cygnett’s AFL Licensed Magnetic Wireless Power Banks come in — compact, powerful, and made for match day.

These Power Banks are ultra-lightweight at just 104 grams, making them perfect for slipping into your pocket or tossing in your game-day bag. They deliver 10W wireless charging with a strong magnetic grip that snaps securely to MagSafe-compatible phones, and they’ve got a USB-C port too if you prefer wired charging. On top of that, they feature an official AFL licensed design so you can charge up in style while backing your team. Plus, they’re carry-on approved and come pre-charged, so you’re ready to roll from the first bounce.

From siren to siren, this magnetic Power Bank keeps your phone powered so you never miss a moment on or off the field. It’s the game-day essential for every die-hard footy fan.

Choosing the right portable charger for your device

With so many sizes, features, and specs floating around, finding the best portable charger for your phone, laptop, or earbuds can feel like a guessing game. But it doesn’t have to be. You just need to know what to look for. Whether you’re after a slim battery pack for your iPhone or a high-capacity laptop Power Bank, there’s a perfect match waiting for you.

Here’s what to keep in mind while choosing your next portable charger:

How “light” should it be?

If it fits in your pocket and doesn’t drag down your bag, you’re on the right track. A lightweight Power Bank typically falls between 100 to 200 grams. Anything in this range gives you solid battery capacity without the bulk.

Need to charge your phone once or twice while out and about? A 5,000 mAh Power Bank at around 110 grams is ideal. For longer days or extra devices, a 10,000 mAh charger weighing under 200 grams gives you that bit of extra juice without tipping the scales.

The goal is portability and performance — and with the right pick, you’ll barely notice it’s there until you need it.

Is it compatible with your device?

Not all Power Banks work with all devices, so compatibility is key. Start with wattage. You want to make sure the Power Bank is not underpowered for your device. If your device needs 45W of power to charge efficiently, a 12W Power Bank won't give you the best experience. Most smartphones charge optimally between 15W and 30W, while tablets usually require 20W to 30W of power. Laptops need higher wattage, with most models needing at least 45W and some newer releases requiring up to 100W. Always check the wattage specifications for both your device and the Power Bank to find the perfect match.

If you’re rocking an iPhone 15 or later, look for Power Banks with USB-C output or MagSafe wireless compatibility. Android users — especially those with Samsung Galaxy or Google Pixel phones — will benefit most from fast-charging USB-C ports with Power Delivery (PD).

Also, double-check your cable. Some Power Banks come with built-in charging cables, which is super convenient, but only if they match your device's port.

How much power do you really need?

This all comes down to how many devices you’re charging and how often. If you just need a quick top-up for your phone or earbuds during the day, a 5,000 mAh Power Bank will do the trick. It’s small, light, and gives you roughly one full phone charge.

Got a long day ahead? A 10,000 mAh Power Bank gives you up to two full charges for most smartphones or enough to top up your iPad, wireless earbuds, and smartwatch all in one go, as long as the Power Bank has the correct wattage for your devices.

Charging a tablet or even a laptop like a MacBook? You’ll want something with higher wattage and at least 20,000 mAh or more. Just make sure the wattage from the output ports match your device’s requirements, and that the charger has the power delivery (PD) tech to handle your device’s charging speeds.

Just a heads-up though — large capacity Power Banks typically weigh more. If you're picking a laptop Power Bank, expect it to be a little heavier than your everyday phone charger. It’s a trade-off for the extra charging capabilities.

Always check the Power Bank’s specs against your device’s battery size — especially if you’re relying on it for travel or remote work. That way, you won’t be caught short.

Wired or wireless?

Choosing between wired and wireless comes down to how you like to charge. Wired Power Banks are super reliable, fast, and often support higher charging speeds through USB-C or USB-A ports. You just plug in your charging cable, and you’re good to go.

Wireless chargers, on the other hand, are all about convenience. No cables, no clutter. Just snap your MagSafe-compatible phone onto a magnetic Power Bank and let it charge while you keep moving. It’s ideal for those who love minimalism or want to avoid tangled cords while out and about.

That said, wireless charging tends to be a bit slower than wired. And it does drain the Power Bank’s battery faster. So if speed or maximum efficiency matters — go wired. If simplicity is your vibe and you’ve got a MagSafe-compatible device, a magnetic wireless charger is a top pick.

The best part? Many Cygnett options give you both.

Is it carry-on approved for flying?

Yes, you can bring your Power Bank on a plane. But there are a few rules. Most airlines follow international safety regulations that limit you to Power Banks under 100Wh (around 27,000 mAh) in your carry-on bag. Anything higher might need airline approval or may not be allowed at all.

The good news? All of Cygnett’s lightweight Power Banks (5K to 10K mAh) are carry-on approved, so you can toss them in your bag without a second thought.

If you fly often or plan to pack multiple devices, it’s smart to go for one of our dual or multi port Power Banks. That way, you can power up your phone, earbuds, and tablet mid-flight without scrambling for a socket in the airport lounge. 

Always check with your airline about their specific rules for flying with Power Banks and other lithium batteries, as these regulations can change without notice and may differ between airlines.

How long does it take to charge?

If your Power Bank takes all night to fill up, it might not be the right fit for your fast-paced day. Smaller portable Power Banks, like 5,000 mAh models, typically take around 2 to 3 hours to fully recharge, especially if you're using a fast wall charger and a USB-C cable.

Larger capacity Power Banks (10,000 mAh or more) can take between 4 to 6 hours depending on the input speed and your adapter. Look for models with USB-C Power Delivery (PD) input — they recharge quicker than traditional micro-USB or lower wattage ports.

If you need a fast turnaround, check the specs for fast input charging. With the right charger, fast-charging compatible devices can get from 0-50% in about 30 minutes. It can make a huge difference, especially when you're topping up during short windows between work, uni, or travel plans.

How many devices do you need to charge?

Are you just powering your phone, or are you juggling a smartwatch, wireless earbuds, tablet, and maybe even a second phone? The number of devices you need to charge makes a big difference in choosing the right Power Bank.

If you're a one-device person, a compact Power Bank with a single USB-C or USB-A port will do the job. But if you're the type who travels with a full tech lineup, go for something with two or more output ports. Cygnett’s multi-port Power Banks let you charge two or even three devices at once without breaking a sweat.

Some models also offer pass-through charging, so you can recharge the Power Bank while charging your device at the same time. It’s a game-changer for people who live on the move and don’t have time to wait around.

Other features to look for in your next portable charger

Once you’ve got the basics down — weight, capacity, compatibility — it’s time to look at the extra features that take your portable Power Bank from good to brilliant. These little details can boost the functionality of your portable charger:

Built-in cables: No need to pack extra charging cables. Perfect for grab-and-go charging

Magnetic attachment: Great for MagSafe-compatible iPhones. Snaps securely to your phone for cable-free charging

Digital battery indicators: Gives you a clear read of remaining battery life so you're never caught off guard

Dual or multi port output: Lets you charge more than one device at the same time

Durable design: Rubberised or reinforced edges protect against knocks in your bag

Pass-through charging: Lets you recharge the Power Bank while it charges your phone

Solid warranty: Every Cygnett Power Bank is backed by a 2-year warranty, giving you peace of mind that your portable charger is built to last.

Having the right mix of these features means you get more from your Power Bank every time you use it. And that’s what smart charging is all about.

Can a lightweight portable charger fully charge a laptop?

Yes, but you'll need a Power Bank with higher power outputs and charging capabilities.

Smaller 5K and 10K models are perfect for smartphones and earbuds, but for a full laptop charge — especially something like a MacBook — you’ll need a Power Bank with at least 60W of power and 27,000mAh capacity or higher.

Lucky for you, Cygnett’s range includes slim and sleek options that go up to 40,000 mAh. These are built to handle bigger devices like tablets and laptops, with high-wattage output and multiple USB-C ports for serious charging power.

Again, keep in mind that these high-capacity Power Banks are a little heavier and bulkier due to the extra battery life packed inside. Plus, they cannot be taken on any 

flights.

Stay powered without the bulk

No more stuffing oversized chargers into your day bag or dragging bulky bricks just to keep all your devices juiced up. With the right lightweight portable Power Bank, you’ll stay connected, charged, and moving — all without the bulk.

From our feather-light 5K models to slim magnetic options and compact high-capacity chargers, Cygnett has something for every lifestyle. And with smart extras like built-in cables, fast charging, and carry-on approval, you’ll wonder how you ever travelled without one.
