Fantastic upgrade
I had the cygnett charge up pro usb c 20000mah but it was unfortunately stolen on a recent overseas trip. This was my upgrade and it’s a different beast entirely. It is a lot bulkier than the slimmer older one but also has an extra 7kmah. The screen is a fancier feature and comes with a travel case. Highly recommend

At a glance
The Cygnett 27K Laptop Power Bank is a premium portable charger built for people who need serious power for laptops, tablets and phones away from a wall socket. Its strengths are high output, fast recharge, three-device charging and a travel-ready case. The main trade-off is that it is bulkier than smaller power banks designed mainly for phones.

Things to consider
Compared with smaller phone-first power banks, this unit is less pocket-friendly and better suited to bags or desk setups, especially if you are mainly charging lightweight devices.
Home office suitability
9/10 - Excellent for keeping a laptop, phone or tablet powered through desk work, meetings or short outages.
Gaming compatibility score
8/10 - Strong for charging gaming handhelds and many USB-C gaming laptops, but it is not a substitute for an AC power brick in extended high-load gaming.
Student use fit
9/10 - Great for long campus days, shared study spaces and commuting, with enough capacity for multiple device types.
Device compatibility range
Broad compatibility across USB-C and USB-A devices including phones, tablets, laptops, earbuds and other PD-enabled gear
Plug-and-play simplicity
9/10 - Straightforward USB-C and USB-A connectivity with a clear LCD display makes everyday charging simple.
Key benefits
- 27,000mAh Capacity: Provides substantial backup power for laptops, tablets, phones and earbuds when you are away from mains power.
- 148W Total Output: Delivers high combined charging power for demanding devices and multi-device top-ups.
- 140W USB-C PD 3.1 Port: Supports fast charging for compatible laptops and other USB-C devices that need higher power delivery.
- Three-Port Charging: Lets you charge up to 3 devices at once using 2 x USB-C ports and 1 x USB-A port.
- 1.5-Hour Recharge Time: Recharges the power bank from 0 to 100% quickly, helping reduce downtime between uses.
- Smart LCD Display: Shows battery level, charging status and temperature information for easier power management.

- Carry-On Friendly Design: Makes it easier to pack for flights and everyday travel with a compact, travel-ready form.
Q: Can the Cygnett 27K 148W power bank charge a laptop, or is it mainly for phones and tablets?
A: Yes, if the laptop charges via USB-C Power Delivery. This model can supply up to 140W from a single USB-C port, which suits many USB-C laptops. It will not charge laptops that rely on a barrel plug or mains-only charger.
Q: What is the difference between the 148W rating and the 140W USB-C output on this power bank?
A: The 148W figure is the total combined output across its ports, while 140W is the maximum from one USB-C port on its own. For the fastest laptop charging, use a single USB-C port. Power is shared when several devices are connected.
Q: Is the Cygnett 27K Laptop Power Bank allowed in carry-on luggage on flights?
A: Yes, in most cases. A 27,000mAh power bank is roughly 99.9Wh, which is just under the common 100Wh carry-on limit used by many airlines. Keep it in cabin baggage, not checked luggage, and check airline rules before flying.
Q: How can you tell if this Cygnett power bank is charging properly?
A: The built-in LCD display shows battery level and charging status, so it is easy to see whether the power bank is being recharged or is charging another device. It also shows temperature information, which is useful during higher-power USB-C charging.
Q: How long does the Cygnett 27K 148W power bank take to recharge itself?
A: In its fastest charging mode, it can recharge from 0 to 100 per cent in about 1.5 hours. That result depends on using a suitable high-output USB-C PD charger and cable. A lower wattage charger will take noticeably longer.
Q: Does the Cygnett CY5381PBCHE include a wall charger for recharging the power bank?
A: No, the listed inclusions are the power bank, a 1 metre USB-C cable and a protective case. A wall charger is not listed. To get close to the 1.5 hour recharge time, use a higher-output USB-C PD charger rather than a basic phone charger.
