Best Portable Power Stations Under 300Wh
Under 300Wh stations are ideal for phones, laptops, routers, CPAP machines (without humidifier), and LED lights. They weigh 2.8–4.7 kg, cost $199.99–$299, and last 1–2 nights for light use. Not enough for fridges, microwaves, or high-draw appliances.
Who Should Buy Under 300Wh?
- Weekend campers who only need phone, light, and a small fan
- CPAP users who want overnight backup (DC adapter recommended)
- Remote workers who just need laptop + router backup for a few hours
- Anyone who values portability above all — these fit in a backpack
Who Should Skip This Category
- Anyone who needs to run a fridge, microwave, or power tools
- Multi-day blackout preparedness — you need 1000Wh+ for that

Anker SOLIX C300 DC
DC-only (no AC outlets) but the lightest at 2.8 kg with dual 140W USB-C ports. Best for laptops, phones, and CPAP via DC adapter. No inverter means longer runtimes for DC loads.

BLUETTI Elite 30 V2
288Wh of LiFePO4 in a 4.3 kg box with a 600W inverter (tied for the strongest here; Power Lifting to 1500W for resistive loads only), two AC outlets, dual USB-C up to 140W, and a 10 ms UPS. Turbo charging reaches 80% in 45 minutes. The pick if you want to run small appliances, not just charge devices.
