What is a portable power station?

A larger scale power bank incorporating an MPPT (solar controller), a battery and an inverter, along with various input and output ports. They work in a similar way to a generator, allowing users to power devices and mains appliances where there is no access to grid mains power. Battery sizes (energy capacity) and inverter ratings (output power) vary across different models to offer more cost effective and tailored solutions.

When might a portable power station be used?

They can be used for almost anything which requires a power supply when there is no access to mains power. Predominantly with campervans and motorhomes. Businesses like off-grid power without the noise and smell of a generator. Festivals often have a no generator policy. Back up during power cuts to keep essential devices and emergency medical equipment running. Many trades and fleets use portable power stations as a cost effective onboard power solution.

What are Watt hours and amp hours?

A Watt (W) is a rate of power usage. A Watt hour (Wh) is a Watt of power spent every second for an entire hour. A 2000Wh battery would allow you to run an appliance rated at 2000W for one hour or a 1000W appliance for 2 hours. Watt hours can be converted to amp hours by dividing Wattage by voltage (e.g. 1500Wh / 12V = 125Ah).

What does peak or surge power mean?

Certain devices, such as items with motors, use more power when they start up than what they use when they are running. A portable power station's surge power will allow a limited amount of extra power to start these devices.

Can a power station be charged by solar and mains at the same time?

Yes, our products will accept both types of charge at the same time, with priority given to the solar (or DC) charge so you save energy coming from the grid.

How do I convert Ah to Wh?

To convert Ah to Wh, multiply amp hours by the battery voltage. Formula: Ah x V = Wh. For kWh, divide the result by 1,000. Example: a 125Ah battery at 12.5V gives 125 x 12.5 = 1562.5Wh, or roughly 1.5kWh.

How do I convert Wh to Ah?

To convert Wh to Ah, divide watt hours by the battery voltage. Formula: Wh / V = Ah. Example: a 2000Wh battery at 12.5V gives 2000 / 12.5 = 160Ah, or 1.6kWh.

What's the difference between Ah and kWh?

Ah (amp hours) measures electrical charge — how much current a battery can supply over one hour. It is commonly used for DC or battery power. Wh (Watt hours) measures energy use or storage and is used for AC or mains power. mAh is more common for small devices like phones, while kWh is used for larger systems such as home batteries and solar storage.

What's the difference between AC and DC power?

In the UK, AC (alternating current) is what comes from your mains sockets — typically 230V AC. It is ideal for powering household appliances. DC (direct current) is the type of power stored in batteries and used by most electronics. Portable power stations convert DC to AC so you can plug in standard UK devices safely.

Mindful of our Planet

Our products use a specific cell chemistry that is less harmful to the environment and safer during use.

Lithium Iron Phosphate (LFP) batteries are often viewed positively for being environmental and safer compared to other lithium-ion batteries. Unlike other types, these do not contain heavy metals such as cobalt, which is commonly mined using environmentally harmful methods. Furthermore, the raw materials used in LFP batteries are more abundant and cause less harmful emissions when manufactured.

🦶The carbon footprint of manufacturing these batteries is estimated to be 18% lower than that of other lithium-ion batteries.

🔋 The cells have a longer lifespan compared to other lithium-ion chemistries. This means they need to be replaced less frequently, reducing overall waste.

🪫 LFP batteries are more stable under extreme conditions such as overcharging, short-circuiting, or physical damage.

♻️ More recyclable compared to other lithium-ion chemistries due to their simpler chemical composition.
