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

Q: Can this Cygnett 27K power bank charge a laptop, or is it mainly for phones and tablets?
A: Yes, it is designed for laptops as well as smaller devices, because the product is rated at 148W. It suits USB-C laptops that charge over USB-C Power Delivery, but very high-draw gaming models may still drain faster than this bank can refill them during heavy use.
Q: What does the 148W rating mean in real use on this Cygnett laptop power bank?
A: The 148W figure refers to available charging power, not battery capacity. In practice, that means it is aimed at faster USB-C laptop charging than a standard phone bank, but actual speed still depends on the device, cable and whether power is split across ports.
Q: Is the 27K capacity suitable for flights in Australia and overseas?
A: Usually yes, because a 27,000mAh power bank is typically about 99.9Wh at 3.7V, which sits just under the common 100Wh airline carry-on limit. Airline rules can vary, so it should travel in carry-on rather than checked baggage and be checked before flying.
Q: Will this power bank fast charge a phone and a laptop at the same time?
A: It can charge more than one device, but charging speed is shared when multiple ports are in use. A phone can still charge quickly, though the laptop may receive less power than when it is the only device connected, which matters most during heavy laptop use.
Q: Why does this Cygnett power bank include a case?
A: The case is there to make a large-capacity power bank easier to carry and protect in a bag. That is useful because a laptop-grade bank is heavier and bulkier than a phone-only model, and the case helps reduce scuffs, cable snags and day-to-day wear.
Q: Is this a good option for long workdays away from a wall charger?
A: Yes, this model is aimed at mobile work because it combines a 27K capacity class with laptop-level output. It is better suited to topping up a USB-C notebook, phone and accessories through the day than a smaller power bank built mainly for handsets.
