- Look for high surge ratings if you’re powering motor-driven devices.
2. Output Ports
- USB-C PD (Power Delivery) ports are becoming essential for fast-charging phones and laptops.
- AC outlets (with pure sine wave) are critical for sensitive electronics.
- A variety of ports allows for greater flexibility and simultaneous device charging.
3. Recharging Methods
- Some models offer solar recharging via MPPT controllers for faster solar charging.
- AC wall charging and 12V car charging are standard, but fast-charging tech sets premium models apart.
4. Weight & Portability
- Models like MARBERO 88Wh are lightweight (under 5 lbs), ideal for mobility.
- Heavier models like the BLUETTI EB3A offer more power but may not be ideal for hiking.
