Energy AND Power

Every off-grid power option worth knowing about: what it is, how it works, and who it makes sense for. Read it now, before it gets dark.

Rechargeable battery units with AC outlets, USB, and DC outputs. Silent, no exhaust, indoor safe. The default backup for apartments and anyone who wants clean, quiet power.

Lithium-Ion (Li-Ion / NMC)
Most Common
500-800 cycle life. Lightest per Wh, cheapest entry. Good for occasional emergency use and standby, less ideal for daily cycling.
500-800 cycle life Lightest per Wh Price: lowest entry
Lithium Iron Phosphate (LiFePO4)
Longest Lifespan
2,500-3,500+ cycles, more thermally stable. Heavier and more expensive upfront, but buy once and use for a decade. The chemistry to look for if you plan regular use.
2,500-3,500+ cycle life Durability: exceptional Price: higher upfront
Solar Generators (Station + Panel Kits)
Self-Sustaining
Power station bundled with solar panels. Renewable loop: sun charges battery, battery powers gear. Weather dependent — best as complementary charging, not sole source.
Renewable charging Best use: extended outages Weather dependent
What to own
  • Power station, 500-1,000Wh Mini fridge + phones + lights for 12-24h. LFP worth the premium for regular use.
  • Compatible foldable solar panel Paired with station for self-sustaining loop. Aim for 100-200W output.
  • Second, smaller unit (200-300Wh) For travel or a go-bag. Your main station likely isn't moving anywhere fast if it weighs 30+ lbs.

Convert sunlight to electricity for charging power stations and batteries. Portable foldable panels are the practical choice for emergencies — deploy anywhere outdoors.

Monocrystalline Panels
Best Efficiency
20-23% efficiency. Best output per surface area, performs well in partial shade and high temps. The clear choice for portable use.
20-23% efficiency Best use: portable, maximum output Price: mid-high
Polycrystalline Panels
Budget Option
15-18% efficiency, cheaper, heavier per watt. Better for fixed installations where space isn't critical. Monocrystalline wins for portable use.
15-18% efficiency Price: lowest Best use: fixed installations
Flexible / Thin-Film Panels
Ultralight
10-16% efficiency, bendable, ultralight. For vehicle roofs or curved surfaces. Lower output and durability than crystalline types.
10-16% efficiency Best use: curved surfaces, vehicles Flexible form factor
What to own
  • Foldable monocrystalline panel, 100-200W Match to your power station. Check compatible panel specs from your brand.
  • MC4 or DC5525 adapter cables Often not included. Check your station's input port before you need them.
  • Flexible thin-film panel (optional) Only if you have a vehicle with curved roof space.

Combustion engines converting fuel to electricity. Significantly more sustained power than battery stations — enough for major appliances. Loud, outdoor use only, fuel dependent.

Inverter Generators (Gasoline)
Quiet + Clean Power
Clean sine-wave power safe for electronics. 48-58 dB, 1-3kW output. Adjusts engine speed to load, saving fuel. Quietest option.
48-58 dB noise level Safe for electronics Price: highest
Conventional Generators (Gasoline)
Raw Power, Low Cost
Constant speed, louder, less fuel-efficient. But 3,000-10,000W+ output. The tool for running fridge, freezer, and sump pump simultaneously.
3,000-10,000W+ output 65-75 dB noise level Price: lowest per watt
Dual-Fuel Generators (Gasoline + Propane)
Fuel Flexibility
Gasoline goes stale in 3-6 months. Propane stores indefinitely. ~10-15% output drop on propane, but fuel flexibility is the point for extended outages.
Gasoline + propane Propane stores indefinitely Best use: extended outages
Propane-Only Generators
Clean Burning
No stale fuel, no carburetors to clean. Fewer consumer options and slightly higher fuel consumption. Best if you already have a propane tank on property.
No fuel degradation Maintenance: minimal Fewer consumer models
What to own
  • Dual-fuel or inverter generator Size to your load. Most homes: 3,000-5,000W for fridge, lights, and outlets.
  • Fuel stabilizer Untreated gas stales in 3-6 months. Stabilizer extends to 24 months.
  • Approved fuel cans (5-10 gallon) Full tank minimum at all times. Rotate every 12-18 months.
  • Heavy-gauge generator extension cords Standard cords overheat under generator loads — fire risk.
  • Transfer switch or interlock kit Required for safe home panel connection. Licensed electrician install.

Portable batteries for charging phones and small electronics via USB. The most accessible form of backup power — small, cheap, and the first thing that keeps communication alive.

Pocket / EDC Power Banks
5,000-10,000 mAh
1-2 phone charges, pocket-sized. The one you have on you when it happens, not the one in a drawer. $15-50.
1-3 phone charges Best use: daily carry Price: $15-50
High-Capacity Power Banks
20,000-30,000 mAh
5-7 phone charges or a laptop. 100W+ USB-C PD models charge MacBooks at full speed. Right choice for go-bags and multi-day outages.
5-7 phone charges Best use: go-bags, laptops Price: $50-120
Solar Power Banks
Self-Charging
Standard bank with a small built-in solar panel. 5-10W input, full solar charge takes 20-40+ hours. A last-resort trickle, not a primary charging method.
5-10W solar input Solar: last-resort trickle Best as: bank + solar backup
What to own
  • Pocket bank, 10,000mAh, always carried In your bag, not on a shelf. First line of defense.
  • High-capacity bank with USB-C PD, in go-bag Laptop + several phone charges. Real multi-day staying power.
  • Multi-cable kit (USB-C, Lightning, Micro-USB) A bank with no matching cable is useless.
  • One pocket bank per household member Everyone needs a charged phone. Sharing is not a plan.

Light is the first thing you notice when power goes out, and the easiest to solve. Battery, USB, and fuel-based options cover every scenario.

Battery / USB Lanterns
Most Practical
50-200+ hours on low mode. USB-rechargeable models pair with power banks or stations. Multiple brightness modes, hanging hook for hands-free use.
50-200+ hrs runtime USB-C rechargeable options Room-filling light
Fuel Lanterns (Oil / Candle)
No Electricity Needed
No batteries, no charging. Lamp oil stores for years, candles indefinitely. Ventilation and fire safety required. Dietz hurricane lantern is the classic choice.
7-12 hrs per fill Fuel stores for years Ventilation required
Headlamps + Flashlights
Hands-Free / Focused
Hands-free task lighting. 300-800+ lumens, red light mode preserves night vision. USB-rechargeable. A lantern + headlamp covers all lighting needs.
100-800+ lumens USB-C rechargeable Red mode preserves night vision
What to own
  • LED lantern, 300+ lm, per main room Hanging hook, battery or USB. This lights the room.
  • Hurricane oil lantern + lamp oil Zero tech backup. No batteries, no charging.
  • Headlamp per person, with red-light mode Hands-free is essential. One per person, always charged.
  • Spare batteries (AA, D-cell) Match to your lanterns. Two full sets. Rotate every 2-3 years.
  • Glow sticks (approx. 12) Mark exits in total darkness without draining a lantern.

The small items that fill gaps between major power sources. Stormproof matches, EDC flashlights, hand-crank chargers, battery stock. Individually minor, collectively critical.

Fire Starters
Fundamental
Redundancy is key: stormproof matches, ferro rods (3,000°F sparks, works wet), and windproof arc lighters. At $5-15 each, have all three.
Multiple methods recommended Waterproof options available Price: $5-30
EDC Flashlights
Every Day Carry
Pen-sized, 200-500 lumens, USB-rechargeable. The point is having a light on you at all times — in your pocket, not in a kit.
200-500 lumens USB-C rechargeable Pocket-clip design
Hand-Crank Chargers
Last Resort
10 minutes cranking = ~1-3% phone battery. Slow, but zero dependencies. Emergency crank radios with AM/FM/NOAA + flashlight + USB are the most practical form.
1-3% per 10 min cranking No dependencies whatsoever Best use: last resort only
Battery Supply (AA, AAA, D-cell)
Stock Up
Most emergency gear runs on AA/AAA. Alkaline: 10-year shelf life, cheap in bulk. NiMH rechargeable: 2-5 years stored charge, better long-term value.
AA, AAA, D-cell cover most gear Alkaline: 10-year shelf life NiMH: 2-5 yrs stored charge
What to own
  • Stormproof matches (2+ boxes) Burns in rain and wind. Store in waterproof container.
  • Ferrocerium rod with striker 3,000°F sparks, any weather, lasts thousands of strikes.
  • Windproof arc lighter (1-2) USB-C rechargeable. Works in conditions that kill flame lighters.
  • EDC flashlight, pocket-clip 200+ lumens. Always clipped, always on you.
  • Hand-crank emergency radio with USB NOAA alerts with no power source. Last-resort phone charge.
  • Battery stock (AA, AAA, D-cell) Match to your gear. NiMH for long-term, alkaline for rotation.
