The short version: Ignik's Topside heated blanket and Flipside heated bed cover each draw up to 48W from a 12V socket that can supply 4A. Ignik's manual puts one night at about 250 to 300Wh. A 12V 100Ah lithium house battery covers several nights of one blanket. A power station works too if its 12V car port delivers 4A and it holds at least the 250 to 300Wh Ignik asks for (Ignik's website prefers 500Wh or more). Heating the bed takes a fraction of the power needed to heat the whole camper, which is why this works off-grid at all.
Topside or Flipside: over you or under you
| Model | Where it goes | Size / sleepers | Max output |
|---|---|---|---|
| Topside Heated Blanket | Over you; cape-mode connectors let you wear it around camp | 1 person | 48W |
| Topside Fleece | Same, with brushed fleece and micro-suede | 1 person | 48W |
| Flipside Heated Bed Cover | On the mattress, under you | 1 person, 25 x 72 in | 48W |
| Flipside Fleece | On the mattress; fleece top, micro-suede backing that helps it stay put | 1 person, 25 x 72 in | 48W |
| Flipside Double | Two connected covers on a shared bed, each with its own controller | 2 people | Two covers' worth (see below) |
The Flipside's side snaps can join two or more covers for more sleepers or a larger bed. The Topside suits a dinette nap or a cold evening outside as much as bedtime. Every model uses the same smart controller: heat levels 10 to 100 in steps of 10, an auto shut-off timer from 1 to 10 hours, and memory of your last settings. Ignik suggests starting at level 60, waiting 5 minutes, then adjusting. It takes 5 to 10 minutes to reach full heat.
What it needs from your power
- 12V nominal only. The manual says to connect to a 12V auxiliary output rated for 48W or higher (12V, 4A), through the included car plug or the 5.5 x 2.1 mm barrel.
- Not your starting battery. Ignik recommends a dual-battery system so the blanket can't drain the battery that starts your vehicle. In an RV, that means the house battery.
- Not a generic wall adapter. The manual warns against 100 to 240V AC-DC wall adapters, transformers and power supplies, and says using one voids the warranty. Ignik does sell its own AC/DC Wall Adapter for its heated blankets. On shore power, the simplest route is the RV's 12V system, which the converter keeps topped up.
- One known mismatch. Ignik lists the Topside and Flipside as not compatible with the Anker SOLIX C1000. It doesn't say whether that includes the C1000 Gen 2, so check with Ignik before pairing them.
How long it runs on a battery
Ignik gives three ways to estimate run time:
- Per night: about 250 to 300Wh for one product for one night, 500 to 600Wh for two products (or two nights), and about 1,000Wh for four nights (or two products for two nights).
- Measured on power stations: Ignik's battery chart lists 12 to 14 hours at heat level 100 on a 505Wh Goal Zero Yeti 500X, 24 to 28 hours on a 983Wh Yeti 1000X, and 36 to 42 hours on a 1,516Wh Yeti 1500X. Those work out to an average draw of roughly 35 to 42W at level 100, below the 48W peak, because the controller cycles the heat.
- Worst case: 48W continuous.
The table applies the 48W worst case and Ignik's per-night figure to common batteries. Usable capacity uses our standard planning assumptions: lithium (LiFePO4) = Ah × 12.8V × 0.9; AGM = Ah × 12V × 0.5, since you shouldn't drain lead-acid below half; power station = rated Wh × 0.85 for conversion losses. Real results vary with temperature, heat setting and what else is running.
| Battery | Usable (assumption) | Hours at 48W non-stop | Nights at 250 to 300Wh (one blanket) | Nights for a Flipside Double (500 to 600Wh) |
|---|---|---|---|---|
| 12V 100Ah lithium, e.g. LiTime 12V 100Ah Group 24 | 1,152Wh | 24 h | 3.8 to 4.6 | 1.9 to 2.3 |
| 12V 100Ah AGM | 600Wh | 12.5 h | 2.0 to 2.4 | 1.0 to 1.2 |
| 500Wh power station | 425Wh | 8.9 h | 1.4 to 1.7 | Under one night |
| 1,000Wh power station | 850Wh | 17.7 h | 2.8 to 3.4 | 1.4 to 1.7 |
Check it yourself: hours = usable Wh ÷ 48; nights = usable Wh ÷ 300 (low end) and ÷ 250 (high end). Remember the blanket is rarely the only load. A 12V fridge, a furnace blower or a diesel heater draws from the same battery. Our diesel heater battery sizing guide shows how to total an overnight load.
The Flipside Double
The Double is two covers joined, with a splitter on the 12V adapter, so plan on two products' worth of power: Ignik's manual puts that at 500 to 600Wh a night. Ignik's Double product page describes its output as "96W max heat output per side". That doesn't fit the 48W rating of each single cover, so for sizing we use the manual's two-product figure and assume 96W total when both sides run flat out. Your socket or power station port should be rated for that.
Picking a power station for it
Ignik's own guidance is a 12V car port that delivers 4A (the manual says rated for 48W or higher) and, ideally, at least 500Wh. Its chart names Jackery Explorer 500 to 1500, EcoFlow River Pro series 500Wh and up, BLUETTI EB55 and AC200P, and Anker PowerHouse 555 to 1024Wh among stations it expects to work. Those are older model lines, so confirm the 12V port rating on whatever station you choose. Browse our portable power stations, and see what size Jackery you need for an RV to size the rest of your loads. Run the blanket from the station's 12V car port, not through an inverter and a wall adapter.
Cold-weather notes
- How warm it gets: the manual puts the element at up to 130°F, measured on the wire, and the pad surface at up to 95°F. The number on the controller is a heat level, not a temperature.
- Lithium batteries in the cold can power the blanket below freezing but must not be charged below about 32°F. See our self-heating lithium guide if the battery lives in an unheated bay.
- Heat the bed, not the cabin. Compare a 1,500W space heater, which our RV heating comparison rules out off-grid. A 48W blanket uses about 3% of that.
Safety rules from the manual
- Lay it flat. Don't fold or roll it while it's on. Ignik does suggest folding it for the first 10 minutes to warm up faster, then flattening it.
- Don't use it as a heating pad, a sleeping-bag insert or an inflatable-pad cover, and don't pin it.
- Don't use it with a child, an infant, or anyone who can't feel heat or adjust the control.
- Spot clean only with a damp cloth. No machine washing, dry cleaning or soaking.
- Unplug it when you're done so it can't drain the battery.

FAQ
Will a 100Ah lithium battery run a Topside all night?
Yes, with room to spare. At Ignik's 250 to 300Wh per night, a 12V 100Ah LiFePO4 battery (about 1,152Wh usable) covers roughly four nights of one blanket on its own.
Can I plug it into my truck's 12V socket?
Yes, if the socket supplies 12V at 4A or more. Ignik recommends a dual-battery setup so you don't drain the starting battery overnight.
Does the Topside come with a battery?
No. A 12V vehicle adapter is included. The battery or power station is not.
Can I run it on shore power?
Run it from your RV's 12V system, which the converter supplies on shore power. Don't use a generic 100 to 240V wall adapter: Ignik says that voids the warranty.
Topside or Flipside?
The Flipside goes on the mattress and warms you from below, so it suits a camper bed or rooftop tent. The Topside goes over you and doubles as a wearable blanket around camp.
