I just want to keep my laptop and phone running.
Then you probably do not need a giant home-backup battery. This is the compact end of emergency power: enough to keep your essential electronics useful without hauling around a 60-pound box.
Choose by the problem, not the specs
A USB-C PD power bank is the smallest, cheapest answer.
Look for a good USB-C power bank that can accept power from a separate folding solar panel.
A compact power station around 250–300Wh gives you substantially more stored energy while remaining easy to carry.
Three compact stations worth comparing
We narrowed this category to three established options with LFP batteries, useful laptop charging and solar capability. You do not need a 20-product comparison chart.
Anker SOLIX C300
288Wh · 300W AC · up to 140W USB-C · 100W solar input
A particularly strong fit for laptops, phones, tablets, cameras and other electronics. The high-power USB-C ports can let you skip the laptop's AC brick entirely when your laptop supports USB-C charging.

245Wh · 300W AC · 100W USB-C · up to 110W solar input
Compact and light, with AC outlets plus USB-C. It makes sense when you want a small emergency battery that can also handle lights, a router and other low-draw devices.

288Wh · 300W AC · 100W USB-C · up to 100W solar input
About 8.3 pounds with a straightforward 288Wh/300W design. A good fit if portability and simple operation matter more than having the most ports or features.

How long will one run a laptop?
Do not trust a single runtime promise because laptops vary enormously. A 288Wh battery does not mean 288Wh reaches your laptop after conversion losses. As a simple example, a laptop averaging 50W for four hours uses about 200Wh. A gaming laptop drawing heavily can empty the same battery much faster.
Do I need the solar panel?
Not automatically. If you expect electricity to return before the battery is empty, buy the battery first. If you need to keep producing power for days without a working outlet, solar becomes much more valuable.
In this compact power-station class, roughly 100W is a sensible panel size because these stations accept about 100–110W of solar input. Buying a huge panel does not force a small station to accept more solar than its input limit.
