A laptop Power Bank keeps you working when the wall socket is nowhere in sight. Back-to-back meetings, long travel days, a stretch of work far from your desk, these are the moments your laptop battery gives out first.
Cygnett builds a full range of portable power banks for laptops, from 20,000mAh up to 45,000mAh, with output from 65W to a hefty 140W. Perfect for MacBooks and Windows laptops to high-performance gaming laptops and everything in between.
Portable chargers come in two camps. Phone-sized ones, and laptop-grade ones.
Laptops draw far more power than phones, so they need more capacity and higher output. A phone charges at 18W to 30W, while most laptops want 45W or more to charge at full speed. Phone power banks also usually hold only 5,000 to 10000mAh, but most laptops need about 20000mAh to fully charge.
That’s why a phone Power Bank will not charge a laptop properly. You need the bigger battery banks built for the job.
Power Bank capacity is measured in mAh, or milliamp-hours, and it sets how many charges you get before the bank runs flat. More mAh means more charges before the Power Bank itself needs a top-up.
Here’s a simple guide across our range:
Wattage decides how fast your laptop charges, and sometimes if it charges at all.
Most laptops need at least 30W to charge while in use. Ultrabooks like the MacBook Air and Samsung Galaxy Book fast charge on 65W to 70W, while powerful machines like the MacBook Pro and gaming laptops want 65W to 100W or more.
Check the wattage printed on your laptop's own charger. Then choose a portable laptop charger that matches or exceeds it.
Pair your Power Bank with a charging cable and wall charger that support fast charging, so you refill the bank at full speed too.
Cygnett's laptop Power Banks carry multiple ports, so your laptop, phone and more charge together.
In most models, you will see a mix of both USB-C and USB-A ports. USB-C ports deliver the high wattage for laptops, newer phones and tablets to charge at high speed, while USB-A ports handle older devices and accessories.
Count your devices before you choose. Two USB-C ports suit a laptop and a recent phone, and a model with four ports can charge a laptop, phone, tablet and an Apple Watch at once.
Size and weight decide how easily a Power Bank travels. Our Encore 20K range, for instance, weighs 412 grams and slips into a jacket pocket, while higher-capacity models sit around 615 to 640 grams. If you travel a lot, you’ll want something that won’t drag you down but with enough power to last through your day.
Travel features matter too. Many models add a digital display for an exact charge level and a removable desk stand. Cygnett Power Banks with 27,000mAh and below capacities are also carry-on approved since they sit under the 100Wh airline limit. Always check your airline's requirements before you fly, since these rules vary between carriers and can change at any time.

1. How long does a laptop Power Bank last on a single charge?
It depends on their battery capacity (mAh), your laptop’s battery size, and what else you charge at the same time. Higher mAh means more power to keep your laptop and other devices charged for longer.
2. How do I recharge the Power Bank itself and how long does it take?
Every Cygnett laptop Power Bank recharges via a USB-C port. So you can charge them via an AC wall charger, a car charger, or solar panels, as long as they match the Power Banks input wattage. Recharge time depends on input wattage, and our 27K 148W flagship refills from 0 to 100% in about 1.5 hours with a 100W source.
3. Will a Power Bank harm my laptop battery?
No, a Cygnett laptop Power Bank will not harm your laptop battery as long as the wattage matches the required power rating of your laptop. It delivers regulated power through Power Delivery, with built-in protection that manages voltage, current and temperature for a safe charge.
4. Are there wireless Power Banks for laptops?
No, laptops can only charge through a wired connection rather than wirelessly, since wireless charging tops out around 15W and a laptop needs 60W to 100W.
