What small tech upgrade helps during power cuts?

[QubitZero]

I want something useful for outages, travel delays and general emergencies. What is worth buying?

[Ben]

A serious power bank is the first thing I would buy. Anker 737 Power Bank can keep phones and some USB C devices going when mains power is not available

A streaming stick like Roku 3820EU Streaming Stick 4K is less useful during the outage itself, but handy when travelling and plugging into hotel TVs

For actual emergency use, prioritise phone charging, torch battery and mobile data before entertainment

Keep it charged. A dead power bank in a drawer is just expensive plastic
