Keep phones, Wi-Fi and a laptop alive without buying a giant battery.
You have two sensible levels. Spend very little if your main problem is phones. Step up when you also want Wi-Fi, laptops, AC outlets and solar recharging.
Anker Nano Power Bank A1259
10,000mAh · built-in USB-C cable · up to 30W
Phones and small USB devices. It is the inexpensive answer when you do not need AC outlets or to keep a laptop and router running for hours. A 10,000mAh bank is generally in the neighborhood of roughly one to two modern-phone recharges after normal conversion losses, depending heavily on the phone.
This is not a tiny power station. That is the point. If all you need is communication power, do not spend hundreds of dollars solving a bigger problem.
See Anker Nano on Amazon →BLUETTI Elite 30 V2
288Wh LiFePO₄ · 600W AC · 200W solar input · 140W USB-C · ≤10ms UPS
Roughly: a 10W Wi-Fi router for about 20–24 hours; a 50W laptop for about 4–5 hours; router + 50W laptop together for about 3.5–4 hours; or several phone recharges plus other small electronics. High-draw gaming laptops will run much less.
Add a compatible solar panel later: the station can accept up to 200W of solar input, so a separate panel can turn it from a one-shot battery into a rechargeable outage setup. Actual solar production varies with clouds, shade, heat, season, panel angle and the panel you choose.
If the real job is keeping phones alive, buy the cheaper Anker and stop there. If you need Wi-Fi, laptop power, AC outlets, UPS-style switchover or a meaningful solar-recharge path, the BLUETTI is the upgrade.
We own and have used it, but it is discontinued, uses older AGM battery chemistry and is not what we recommend buying now. What we still like is the architecture it taught us: stored power plus a separate solar panel.

Runtime is roughly usable watt-hours divided by average watts. We allow for conversion losses. Real runtime changes with device draw, temperature, battery state and whether AC conversion is required.
| Load | Planning estimate on BLUETTI 288Wh |
|---|---|
| 10W router | About 20–24 hours |
| 50W laptop | About 4–5 hours |
| Router + 50W laptop | About 3.5–4 hours |
| 100W continuous load | About 2–2.4 hours |
UPS vs power station
A normal power station does not automatically provide uninterrupted switchover. BLUETTI specifies the Elite 30 V2 at ≤10ms UPS switchover. For critical medical or computer equipment, follow that equipment manufacturer's backup-power requirements.
