And in the home, a portable power station is an essential item to have on hand when the grid goes out and you’re left with no power at all.

excellent battery management offering more safety

This model has three 30000mAh lithium-ion battery cells managed by a Battery Management System (BMS) which provides protection from:

  • Short-circuit
  • Over-current
  • Over-charging
  • Low-voltage
  • Over-heating

It’s also equipped with a fan to help ensure the unit remains within its operating temperature limits.

recharging the power station

The G300 can be charged in up to three ways: AC wall outlet, solar panel, and a car’s 12V socket. Although Recharging time can vary depending on a number of factors including location, temperature and weather, as a general guide you can expect recharging of around:

  • 5-6 hours to fully recharge from an AC wall outlet (60W AC adapter included),
  • 6-7 hours from a 12V/24V car port
  • 6-7 hours using a FlashFish 50W or FlashFish 60W solar panel (paid links)

power outputs and input

Despite its diminutive dimensions this FlashFish model is equipped with some useful outlets, which include:

  • 2x110V 300W (Peak 350W) AC Pure Sine Wave
  • 1xUSB (5V/2.4A)
  • 2 Quick Charge 3.0 USB outputs (18W QC3.0, 5V/2.4A)
  • 1xCigarette lighter socket output (12V/10A)
  • Input: 5.5×2.1mm DC, 15V/4A

The two 300W continuous AC outlets have a momentary surge (peak) rating of 350W. And you won’t need to be concerned about damaging any of of the sensitive components in your electronic equipment, such as CPAPs and laptops, as the power station’s AC outlets produce a Pure Sine Wave output similar to that which you are used to from you wall outlets at home.

eco-friendly clean indoor and outdoor power

While gas-powered portable generators have an important, and sometimes vital, role to play in the lives of many people who have limited or no access to grid power, it’s always a pleasure to be able at times to forget their noise and potentially dangerous fumes. And this is where portable power stations can step forward to supplement a portable generator when power needs are not so great. It might also be the only option for people who live in apartments and for obvious reasons are prohibited from using a portable generator.

But portable power stations really come into their own when hiking and camping due in most part to their relative light weight and unrivalled portability.

versatile recharging

Three methods to recharge the G300, and with either the FlashFish 50W or the FlashFish 60W Solar Panels (paid links) you have the potential for virtually limitless power on the go.
