330W of continuous portable power

The E300 is another offering from FlashFish designed to fulfill the needs of campers and anyone else who enjoys and wants to make the most the freedom of outdoor life offers.

It has a compact body measuring 8.23 x5.19 x7.56 inches, and is built to be light and easily carried when trekking or on a campsite. Homeowners may also appreciate the bright LED lighting during a blackout as they will be able to find their way around in the dark.

Outstanding battery safety and power saving technology

Th 300Wh lithium-ion battery is managed by a Battery Management System (BMS) which provides protection from:

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

And a fan is built-in to help ensure the unit remains within its operating temperature limits either when on charge or providing power to external devices.

When not connected to any devices the unit will switch off to save battery power.

Ways to recharge the E300

The E300 can be charged using at least three methods:

  • AC wall outlet
  • Solar panel(s) - (either 2x50W or 1x100W)
  • A 12V socket as found in a car

The time to recharge the E300 can vary due to location, temperature, and weather conditions. Generally, you should experience times of about:

  • 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 100W solar panel (comes with a 4 in 1 connector adapter kit)

Control panel power outputs and input

The control panel is simple and functional. It has an LCD panel so you can keep a close eye on AC/DC input and output wattage and the state of the battery in terms of remaining time and charging status.

The outlets include:

FlashFish E330 Control Panel
  • 2x110V 330W (Peak 380W) AC Pure Sine Wave
  • 2xDC 12V~16.8V/168W Max
  • 1xUSB (5V/2.4A)
  • 2 Quick Charge 3.0 USB outputs (18W QC3.0, 5V/2.4A)
  • 1xDC 21.5 DC socket output (24V/3.8A Max) (12V/10A)
  • 1xDC Input/Solar Input (V/3.4A)
  • Solar Input: 18~24V - for 2x50W or just 1x100W Solar Panel(s)

Both of the 330W continuous AC outlets can withstand a momentary surge (peak) power of 380W, and their Pure Sine Wave output provides a safe and steady stream of power that won't harm any of your sensitive electronic devices.

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, a power station has the advantage of being silent in operation and don't present any problmes with carbon monoxide fumes.

For anyone living in an apartment, a portable power station could be a valuable possession by providing them with vital power during a power outage.
