I have the CUKTECH 10 and it's a great power bank, I would have no issues purchasing any of their other devices.
I specifically use it to power my T-Mobile Home Internet gateway during power outages and it can run it for and 3.5 hours. This device here would be even better if it would switch from charge to battery in a power outage like a UPS, even if the device had to reboot that would be fine.
The Cuktech CP16 has launched in China as a competitor to the Anker PowerCore Fusion 5000. At the core, it's a 2-in-1 power bank that can also act like a charger, and it has support for 67W fast charging.
