Nelpuni What’s worth it.

Preparing your calculation…

Plan the power for your trip

Start with the number of days, adjust your appliances and compare batteries and solar panels. The starting example is a camper without electric cooking; you can change it.

See my result ↓

1. What is your trip like?

A week away does not always need a week of battery power: what matters is how long you will go without a reliable recharge.

We size the battery for the whole trip. You can explore solar panels afterwards without subtracting their output from the calculation.

This is the time we ask the battery to cover. We do not automatically subtract solar, vehicle or campsite charging.

Prefer to start with an example? ↓

2. What will you take and how long will you use it?

Choose every device you will use, even if you use them at different times. Enter the total hours of use per day. To estimate the power needed from a 230 V outlet, we assume those devices could run at the same time.

Add your appliances. Press a card to edit it. Startup and connection compatibility remain unverified.

How we estimate energy use ↓

Adjust daily operating hours. Efficiency assumptions: DC 95% and AC 85% , with 15 W inverter consumption over 24 hours if AC loads are present. Check each appliance's voltage and port.

Your trip, in plain language

2 days away; 2 days of battery power without counting recharges.

Review the batteries first. Choose one to check which panels you can connect; enough watts alone do not make a kit compatible.

Some batteries have enough capacity for your usage time; further checks are needed.

4 options remain under consideration and have capacity for the time entered. Check power, startup and connections.

See these options ↓

Before choosing, check connections, startup and operating conditions. Capacity alone does not guarantee that your appliances will work.

Your car-powered or USB appliances need a compatible connection. Check their ports in the result.

No AC inverter is required. Estimated DC efficiency is 95%; connectors, voltages and per-port limits still need verification.

AC and DC startup, assessed separatelyNo AC loads

No AC startup increase has been modelled. This does not verify DC load startup or your appliances' actual behaviour.

DC/USB appliances are active. A fridge or pump may need its own startup surge: check the surge, duration and port limit. A 0 W AC surge does not mean there is no DC startup surge.

I already have panels: wattage simulation ↓
Solar estimate (75% efficiency assumption)

Select your solar panel power to estimate the peak sun hours (PSH) needed to replace daily consumption:

With a panel rated at 200W (effective output of ~150W):~3.8 PSH to replace daily consumption
Assign your DC/USB appliances to specific ports ↓

You have not chosen a model yet. Select one above to check its ports; no connection has been assessed.

3. Your estimated needs: 566 Wh per day and 1257 nominal Wh for 2 days without recharging.

Wh tells you how much energy a battery stores: it helps estimate how long it will last. W is the power an appliance needs while running. Enough stored energy does not guarantee suitable sockets or connections.

Options to review: 4. Of these, energy covered: 4; with other checks pending: 4.

Check what still needs checking for each option. We do not guarantee that all your devices will work or that medical equipment will keep running without interruption.

Inside, choose the model you want to check. This clarifies questions about your connections, but it does not certify that the setup will work in practice.

How it is calculated and what needs checking ↓

Assumptions: AC 85%, DC 95%, inverter 15 W for 24 h/day if AC loads are present, usable capacity 90%, margin 15%. Fridge compressor hours do not reduce AC availability time. All active AC loads are assumed simultaneous, with one startup modelled at a time. Solar: 75% and 4.5 PSH for guidance; recharging does not reduce required runtime. Prices are references without a verified current offer.

Warranty, cycles under verified conditions, usable energy, price and reviews remain unverified.
  • EU JE-2000D: documented 230 V/50 Hz and normal 2200 W total AC output. The 4400 W figure is a peak without an established duration and does not prove startup.

4. Which solar panels can you connect?

Choose a battery above. Here you can check how much energy panels might provide and whether their connection is documented. The sunlight estimate does not replace the battery days you requested.

Optional recharging

Would you like to recharge with solar panels?

Choose a battery first. Then you can look for solar panels and check the cable. Recharging does not reduce the battery capacity you need for your planned days.

Choose a battery above. We will use your energy use and required runtime to show its solar options here.

Before choosing

Understanding changes the decision.

01 / Power and capacity

W to start.
Wh to keep going.

Watts indicate the power you can supply at the same time. Watt-hours describe available energy; runtime also depends on losses and actual consumption.

02 / Service life

Cycles need
context.

Check chemistry, capacity threshold and test conditions. Declared cycles do not guarantee a lifespan in years or certify every use.

03 / Charging

The quick figure
does not tell everything.

Distinguish 0–80% from 0–100%. Review mode, temperature, input limits and included accessories before comparing times.

Questions worth asking.

What is the difference between a LiFePO4 battery and a conventional lithium one?

LiFePO4 is also a lithium-ion chemistry. Compare declared cycles and their conditions in each model's documentation: they do not equal guaranteed years. Temperature, storage and use affect ageing; every battery requires following the manufacturer's safety instructions.

Can I use an air fryer or Nespresso coffee machine with these stations?

It depends on the appliance. Check its nominal and start-up power, the station's continuous output and other simultaneous loads. A 1,800 W inverter does not ensure compatibility with every coffee machine or air fryer. Special reduced-voltage modes do not equal more continuous power.

How long does a full recharge with solar panels take?

It depends on the missing energy, irradiation, losses and solar input limit. As a theoretical example, 1,000 Wh divided by a constant 400 W is 2.5 hours before losses; this is not an observed recharge time. Also check voltage, current and connectors of the panel and station.

Is an all-in-one portable station better than a fixed camper installation with a secondary battery and relay?

A station can simplify portable use and a fixed installation can better suit permanent loads. Compare capacity, power, charging and the complete budget. If you modify the vehicle or install fixed wiring, confirm your installation requirements with an ITV centre or competent professional.
