Powerstation for laptop and remote work: your own power anywhere

Charge your laptop without a wall outlet? Work anywhere

Remote work is more than working from home. Perhaps you regularly work:

• from a motorhome or caravan;
• in a garden or on a terrace;
• from a temporary project site;
• on a construction site or at an event;
• during field research;
• from a holiday home or cabin;
• in locations where there is no electricity connection yet;
• on the road as a photographer, consultant or service technician.

You can usually arrange internet via a mobile hotspot, 4G or 5G router or Starlink. But without power, your laptop, router and other devices will eventually stop anyway.

A Mobisun works as a portable outlet with battery. Charge the system in advance and connect your equipment directly. With a matching solar panel, you replenish the energy supply while working.

What equipment can you connect to a powerstation?

Depending on the model and total consumption, you use a Mobisun for:

• laptops and notebooks;
• smartphones and tablets;
• a second monitor;
• mobile Wi-Fi routers and 4G/5G equipment;
• Starlink Mini;
• LED lighting;
• cameras, drones and battery chargers;
• walkie-talkies;
• measuring and test equipment;
• low-power printers and scanners;
• security cameras;
• audio equipment;
• power tool batteries;
• other equipment within the maximum power rating.

A powerstation supplies electricity, but does not provide the internet connection itself. For full remote work, you also need a mobile or satellite connection.

Why a Mobisun powerstation for remote work?

Compare powerstations for remote work

Do not choose on battery capacity alone. Also check:

1. the maximum power of your equipment;
2. the charging power of your laptop adapter;
3. how many devices you want to connect at once;
4. how many hours you want to work without grid power;
5. whether you can top up with a solar panel during the day.

How long can you use a laptop with a powerstation?

Usage time depends on the actual power consumption of the laptop — and this changes during use. Video editing, heavy software, maximum screen brightness and video calls use more energy than word processing or email.

For a first estimate, use this formula:

The 0.85 factor compensates for the energy loss of the 230V inverter.

Indicative example at 60W continuous consumption

This is the extra work time from the powerstation and is independent of the laptop’s own battery.

A laptop charged directly via USB-C is often more efficient in practice than a laptop on the 230V adapter. Actual usage time remains dependent on the device, load, temperature, battery status and other connected equipment.

How to calculate the energy consumption of your complete workspace

Add up the consumption of all devices.

Charging a laptop with a solar panel

A powerstation contains a fixed amount of stored energy. By adding a solar panel, you generate new energy during the workday.

Combine the Pro Air with a folding 60W panel. A 100W panel is available for the Pro Classic and Pro Air 2.0. The Mobisun panels also have USB-A and USB-C outputs, so you can also charge compatible devices directly via the solar panel.

This is how you get the highest yield:

• place the panel fully unfolded;
• avoid shade from trees, buildings or vehicles;
• aim the panel as directly as possible at the sun;
• adjust the tilt angle during the day;
• keep cables and connections clear and dry;
• preferably place your laptop in the shade;
• place the solar panel in direct sunlight.

Actual yield varies with cloud cover, season, temperature, positioning and the number of effective sun hours.

Charge the laptop via USB-C or via the 230V outlet?

Reliable internet at your remote workspace

For professional remote work, both power and internet are essential. Possible internet connections:

• hotspot via your smartphone;
• portable 4G or 5G router;
• fixed router at a temporary location;
• external antenna or PoE connection;
• Starlink Mini at remote locations.

Place a mobile router in a location with good coverage and, where possible, use an efficient USB or 12V connection. This avoids unnecessary conversion losses via 230V.

Before an important workday, also check mobile network coverage, your data bundle and roaming, VPN access, the speed for video calls and a second internet connection as backup.

Who benefits from a mobile power supply?

Work smarter and longer on battery power

Working from home during a power cut

A Mobisun is not only suitable for on the go. Use the powerstation as a temporary backup for your home workspace. During a power cut, you can:

• keep using the laptop;
• charge the phone;
• power the Wi-Fi router or a mobile hotspot;
• connect LED lighting;
• save and send important files.

Pass-through charging means you use equipment while the powerstation itself charges. This is not the same as a UPS with guaranteed uninterrupted switchover. For servers and systems that may not experience even a brief power interruption, use a certified UPS solution.
