    VTOMAN FlashSpeed 300 Portable Power Station (600W Output / 230Wh Capacity)

    In this day and age, most people take access to electricity for granted. Nevertheless, we often underestimate how important it is to be prepared against potential power outages. This is where having a portable power station can come in handy. These battery-powered systems provide you with a backup source of electricity for keeping small appliances powered and your personal devices charged when facing a power outage. Furthermore, portable power stations also give you a reliable power source for times when you’re camping, working outdoors, or even living off the grid. For a portable power station that can keep most electrical and battery-powered devices running, but still small enough to take anywhere, we recommend the VTOMAN FlashSpeed 300.

    The VTOMAN FlashSpeed 300 is a portable power station powered by a LiFePO4 battery that has a 230Wh capacity, a long battery life of 3000+ cycles, and up to 600W power output, while also boasting 10 battery protection functions. The power station also integrates a built-in LCD display screen, a connection panel with 7 output ports, including 2 AC Outlets (300W), a DC Output (120W), a USB-C PD Input / Output (100W max), and 3 USB-A Outputs (12~18W), along with a DC Input (90W max) through which it supports 4 different recharging methods, including via AC power, DC power (via car charging), USB-C PD, or with a solar panel, plus support for pass-through charging. It also features a built-in 3W LED light that has 3 lighting modes including Constant, Strobe, and SOS modes.

    Designed to give users a reliable source of backup power, this portable power station can effectively keep most of your devices powered, whether that’s during unexpected power outages or even when you’re exploring the great outdoors.

    Here’s our in-depth review of the VTOMAN FlashSpeed 300, where we’ll go over the many features this portable power station has to offer you.

    Starting with its size, this portable power station has an ultra-compact footprint, measuring just 10.4 inches long by 5 inches wide by 9.4 inches tall. The unit is also noticeably lightweight, weighing just 7.4 lbs., as it is ergonomically designed with portability in mind.

    Plus, it also comes equipped with a built-in carrying handle that facilitates its transportation.

    Moreover, the device also packs a very durable and high-quality construction, meaning its built to last.

    The same can also be said about its 110W / 19V solar panel, the VTOMAN VS110 Solar Panel (can be purchased together with the power station or separately), which has a IP67 Water-Resistance Rating, meaning it can withstand rain as well as dust.

    The power station’s 110W solar panel is also equipped with a kickstand at the back that provides different angle adjustments, enabling you to set up its solar panel to the right angle for maximum sunlight exposure.

    Moving on to the VTOMAN FlashSpeed 300’s control and connection panel, both of which have a neat, user-friendly interface.

    Starting at the front side of the power station, there’s a built-in LCD display screen that shows its current Wattage Input and Output values, the connection ports that are currently being used, and its remaining battery life.

    In addition, at the right side of the unit, we have a versatile connection panel with 7 output ports that can be used for powering (or charging) multiple devices simultaneously.

    At the top right of the power station’s connection panel, there’s an On/Off button for controlling its DC Output and its LCD display, along with an AC Out button that controls its AC Outlets.

    Below these buttons, there are 2 AC Outlets (110V/60Hz) that offer 300 Watts output each (600W peak).

    BATTERY & BATTERY LIFE

    For its power, the VTOMAN FlashSpeed 300 utilizes a LiFePO4 battery that’s rated to have a 230Wh capacity and a long battery life of 3000+ cycles, meaning this power station offers you approximately 6x the lifespan of lower-end power stations that use Lithium battery cells.

    Its 230Wh LiFePO4 battery can deliver up to 600W of output power while using multiple output ports at once.

    What’s more is that the power station’s battery system also boasts 10 battery protection functions which help ensure the power station operates safely and efficiently at all times. These functions include protection against overcharging, overheating, short circuits, and more.

    As for recharging the power station’s battery, know that you can choose between four (x4) different recharging methods including via AC power (through a wall socket), via DC power (by using your car’s lighter port), via its USB-C PD In/Out port, or by connecting it to its 110W solar panel (if you also purchase it).

    Supports 4 different charging methods – Ac, Dc, USB-C PD, and solar charging

    When charging the power station via AC, DC, or USB-C PD, the power station takes approximately 2.4 to 2.6 hours for its battery to fully charge.

    When charging it with its 110W solar panel, it takes between 3 to 6 hours for its battery to charge from 0% back to 100% power.

    We’d also like to note that the power station also features support for pass-through charging, meaning you can use it for powering up other devices while having its battery recharging simultaneously.

    WHAT’S IN THE BOX?

    Inside their package, users will find: their VTOMAN FlashSpeed 300 Power Station, along with a vehicle cigarette lighter cable, a DC to AC adapter and a dedicated power cable, a 60W USB-C to USB-C charging cable, a 18W USB-A to USB-C charging cable, and a user manual.
