A 4WD camp that moves most days does not need as much solar as one that stays put. The VoltX Topband V1200, a 1200W portable power station with 1,152Wh of capacity, takes up to 120W from a 12V car socket while you drive and up to 550W from VoltX solar blankets when you stop. Using the example day below, a 100W to 160W blanket plus three hours of driving covers a travel day. Rest days without driving need 160W to 200W. Two 12V blankets can run in series within the V1200's voltage limit, but three cannot. Here is how to size solar blankets around your own trip.
What the V1200 Accepts from the Car and the Sun
Car Charging Input at 12V and 24V
The V1200 listing gives its car input as 120W from a 12V supply and 240W from 24V. A four-hour drive at 120W adds up to 480Wh before losses, close to a full day of the example load. A complete refill from empty takes at least 9.6 hours at 12V, or 4.8 hours at 24V. The listing quotes 5.8 hours, which only fits the 24V figure, so plan on the slower rate if your vehicle supplies 12V.
The 550W Solar Window
The V1200 accepts up to 550W of solar between 11.5V and 55V DC and lists a built-in charge controller. It ships with an XT60-to-Anderson cable, which suits blankets fitted with Anderson plugs. As a 1200W power station with a 2,400W peak, it runs a fridge and camp devices comfortably, but at 13kg and an IP20 rating it belongs under cover. The VoltX blankets list IP65 or better, so a sensible layout is a blanket in the sun, with the cable running back to the station in the shade. Our full VoltX Topband V1200 review covers its outputs and other features.
Here’s what one of our customers said about the VoltX Topband V1200 Power Station:
“Although I bought this for camping, it's come in handy more than once for providing power during power outages at home. Several hours of my laptop, NTD and router plugged in and only used 15% of the battery. Easy to use and charge, do recommend.”

How Much Energy a Moving Camp Uses Each Day
An Example Day in Watt-Hours
A 12V compressor fridge is usually the biggest load. Generally, a 46-litre camp fridge runs at 1.03 amp-hours per hour on 12V DC, measured at 32°C outside with a 4°C setting inside. Real use moves with ambient temperature, how often the lid opens, and how well the fridge is insulated, so treat the figure as a warm-weather starting point.
| Item | Assumption | Energy per day |
|---|---|---|
| Camp fridge | 1.03 Ah/h at 12V for 24 hours | 296.6Wh |
| LED lighting | 2 lights × 5W × 5 hours | 50Wh |
| Phones and devices | 4 charges × about 15Wh | 60Wh |
| Daily budget | Subtotal 406.6Wh plus 25% | 508.3Wh |
Illustrative example. The fridge figure is the manufacturer's average at the stated test conditions; lighting and device figures are assumptions; the 25% buffer follows our watt-hour guidance.
Travel Days and Rest Days
On a travel day, the vehicle does part of the work. On a rest day, the alternator stops helping as soon as you park, so solar has to carry the whole load. That difference is why a moving camp can often manage with less solar than a base camp. Short hops are the exception. An hour of driving adds only about 120Wh at 12V, so a day with a brief move between nearby camps behaves much more like a rest day than a travel day. For setups built around a fixed battery instead, see our guide to portable solar setups for 4WD trips.
Matching Solar Blankets to Travel Days and Rest Days
The table pairs common blanket sizes with the V1200 and the 508Wh example day.
| Blanket setup | Solar on a travel day (3 hours of full sun) | Travel day total with 3 hours of driving | Solar on a rest day (5 peak sun hours) | Rest day balance |
|---|---|---|---|---|
| 100W | 240Wh | 600Wh | 400Wh | 108Wh short |
| 160W | 384Wh | 744Wh | 640Wh | 132Wh spare |
| 200W | 480Wh | 840Wh | 800Wh | 292Wh spare |
| Two 200W in series | 960Wh | 1,320Wh | 1,600Wh | 1,092Wh spare |
Illustrative only. Solar figures assume a blanket delivers 80 per cent of its rating and an Australian summer day of about five peak sun hours, both assumptions used in Outbax guides. Driving assumes 120W from a 12V socket. Cloud, shade, heat, and winter sun all reduce output.

What the Numbers Mean for a Moving Camp
If you drive three hours most days, even a 100W solar blanket keeps the V1200 ahead of the example load. The gap only opens on rest days, when a 100W blanket falls about 108Wh short. With 1,152Wh of capacity, the V1200 can absorb that shortfall for a day or two. Over a seven-day trip with five travel days and two rest days, a 100W blanket finishes about 244Wh ahead at the example load (five days at 92Wh spare, two days at 108Wh short), assuming summer sun. A 160W or 200W solar blanket covers a rest day with room to spare.
Shade and Winter Change the Answer
The table assumes open summer sun. Shade from trees and awnings cuts output hard, and winter sun means recharging takes longer. Solar blankets for camping are easy to move into the light during the day, which helps, but shade or winter conditions are the main reasons to size up from the table.
When a Second Blanket Earns Its Place
A second blanket makes sense if you stop for several days, camp in partial shade, or run a load well above the example. Two 200W blankets total 400W, within the V1200's 550W solar limit, but two 200W ETFE mats weigh 11.4kg together, so the extra output costs space and payload. Outbax lists 100W, 160W and 200W VoltX blankets, so you can mix a light blanket for travel days with a larger one for base camps.

Wiring Blankets to the V1200 Without Exceeding Its Limits
Two in Series Fits, Three Does Not
Series wiring adds voltage while the current stays the same. VoltX 12V blankets list an open-circuit voltage of 21.96V to 22.4V, so two in series reach about 44V to 45V, inside the V1200's 55V ceiling. Three would reach about 66V to 67V, which exceeds it. Under load, two in series run at about 36V, comfortably inside the 11.5V to 55V window. Going over a unit's maximum input voltage risks damaging its charge controller.
Parallel Wiring and the Current Limit to Confirm
Parallel wiring keeps voltage the same and adds current. The product listing does not state a maximum solar input current for the V1200, so confirm it in the manual before connecting blankets in parallel.
What Comes in the Box
The V1200 includes an XT60-to-Anderson cable. The VoltX 12V 200W Folding Solar Mat ETFE Kit includes an MC4 cable, an MC4-to-Anderson cable, and an IP65 junction box, while the panel-only versions include only the mat. The standard VoltX 12V 200W Folding Solar Mat ships with a USB solar controller and an Anderson plug. Our guide to connecting solar panels to a portable power station step by step explains voltage and wiring in more depth.
Here’s what another customer said about the VoltX V1200 Power Station:
“The VoltX V1200 is a powerful and reliable portable power station, perfect for camping, blackouts, or off-grid trips. It has a long-lasting battery, fast 2-hour recharge time, and multiple charging options including solar and car. With 9 output ports, it can run or charge several devices at once. It also features a backup power (UPS) function, built-in LED light, and a clear display screen and weighing 13kg, it's solid! I highly recommend it.”

The best solar blanket for a V1200 covers your rest days at a weight you are happy to carry. On 14 October 2026, the in-stock choices were the 100W and 200W ETFE panel-only mats, which don't include a cable, so plan the connection to the V1200's Anderson lead before you leave.

Weight and Storage in a Loaded 4WD
The 100W ETFE mat is the lightest at 3.1kg, and the 200W blankets weigh 5.7kg to 6.1kg. All fold to 53 to 55 cm long, which suits drawers and back seats. Our guide on what to know before buying solar blankets covers the wider choices.
Sizing Solar for Your Next Moving Camp
The right solar blanket depends on how often you drive, how long you stay in one spot, and how much power your camp uses. For the VoltX V1200, a 100W blanket can cover the example load on days with three hours of driving, while a 160W or 200W blanket gives you more flexibility on rest days.
If you regularly camp in one place for several days or run extra appliances, consider the larger option. Before connecting multiple blankets, check their combined voltage against the V1200’s 55V solar input limit.
