Emergency Power: Plan Ahead

It is just a matter of time before your power goes out. The outage may be short-term, long-term, inconvenient, or an emergency. Don’t play the odds.

In 2012, 632,000 Long-Island homes lost power for 14 days during Superstorm Sandy. I can only imagine the hardship this created. Don’t get caught with your pants down. Plan ahead.

7Step Charging Plan

Planning and securing the items you need to charge your smart devices in a grid-down scenario doesn’t have to be complicated. Following is a list that will help get you started:

#1 Inventory

Take an inventory of your electronic devices and decide what accessories are a priority.  

#2 Charging Devices

Choose charging devices. Have more than one method of charging in case one method fails.

#3 Testing

Test Emergency Charging System(s) before you lose power. The middle of a two-day power outage is not the time to discover that you didn’t purchase an extension cord long enough to reach from your generator to the house or a charge cord that isn’t compatible with your smartphone.

#5 Keep Charged Charge Your Emergency Devices

Keep Your Emergency Devices topped off with charge, so they are always ready in an emergency.

#6 Weather Alerts

If you know bad weather is on the way, you can plan to have everything charged up before a storm arrives. 

#7 Compatible Charging Cords For All Devices

When you are testing, make a list of equipment you need but don’t have, like extension cords, charging cables, or adaptors.

#8 Maintenance

Conduct regular maintenance and have fuel on hand for gas-powered generators.

#9 Organize

Place charging gear in one location so you won’t be running around the house looking for emergency gear in the dark.

Emergency Power: 8 Tools You Can Buy

Eight types of emergency power used during power outages are listed below. These aren’t the only options, but they are the least expensive. It’s a good idea to have more than one emergency power supply in case one fails.

#1 Portable Power Bank

#2 Battery Operated AA/AAA Emergency USB Backup Chargers 

#3 Vehicle Power Inverter  

#4 Portable Power Stations (PPS)/Portable Power Bank (PPB)  

#5 Small Portable Solar Panels and Chargers 

#6 Uninterruptible Power Supplies (UPS) 

#7 Hand-crank Radio Flashlight Combos 

#8 1000 Watt Inverter Generators: Small Gas Powered Generators 

1. Portable Power Bank

Also called: Portable Backup Charger, External Battery, or Portable Laptop Charger

  • .Most efficiently charged from an electrical outlet
  • Charge is held in an Internal Lithium battery
  • Portable backup chargers come in all shapes and sizes.
  • When choosing portable chargers, make sure they are compatible with your device(s)
  • Test the Power Bank before you need it. You might be surprised how certain PPBs don’t work well with specific electronic devices
  • .Keep them charged (preferably at a centrally-located charging station)

2. Battery Operated AA/AAA Emergency USB Backup Charger

  • A USB Backup Charger is a good budget option and is portable. Very handy if you frequently fly or are in area where there is no other way to charge. Just make sure you have batteries on hand.
  • Not a good option for charging a laptop or larger devices.
  • The USB backup charge comes from regular AA or AAA household batteries (Use alkaline or rechargeable batteries)
  • 4 AAA batteries will provide approximately a 50% smartphone charge (% of Charge will vary depending on the brand of the charger)
  • Store extra batteries
  • Test for Compatibility

3. Vehicle Power Inverter

A power inverter converts 12-volt Direct Current (DC) in a car battery into 120-volt Alternating Current(AC) used to charge electronics like a smartphone, laptop, or tablet in a vehicle.

How Do You Use A Power Inverter?

  1. Plug inverter into the cigarette lighter receptacle
  2. Start Vehicle
  3. Charge smartphones, laptops, and tablets by plugging them into the inverter with compatible cords
  4. For safety guidelines and specific characteristics, refer to the user manual for the unit purchased

The inverter will charge electronic devices when the car isn’t running, but it will drain your vehicle battery.

Do not run your vehicle in an enclosed space. Always run your car outdoors, in a well-ventilated area, with an unobstructed exhaust.

Choosing An Inverter For Emergency Power

  • Determine the wattage you need. Smart Devices like smartphones, laptops, and tablets will charge off of a 100-watt Inverter.
  • A typical inverter plug set-up: two three-pronged female receptacles and two USB ports.  
  • Inverters over 150 watts should be professionally installed directly into your car battery.

Watts Needed To Charge A Smartphone

A small 100-watt inverter can charge a laptop, smartphone, and tablet.

  • Smartphones require approximately 2 to 6 watts to charge
  • Laptops require approximately 60 watts to charge
  • Tablets require approximately 12 Watts to charge.

Turn Your Vehicle Into A Generator: High Wattage Sine Inverters

I’d love to have an off-grid van with a huge power inverter if money wasn’t an issue. Large inverter systems are expensive, but a guy has to dream.

  • Professional installation suggested
  • 3000 + watts
  • Large inverters can run large appliances and heavy electronic equipment
  • Battery Bank may be required

Contractor-grade sine inverters run power tools and provide all the power required when working on construction sites without electricity.

4. Portable Power Stations (PPS)/ Portable Power Banks (PPB)

These are fantastic little units. Before researching this article, I wasn’t familiar with Portable Power Stations. Now that I’ve done some research, I want one.

What is a Portable Power Station?

A PPS is a capable electric generator consisting of a large rechargeable lithium battery and a control unit.

  • PPS can be used indoors, unlike internal combustion generators
  • Quiet Operation
  • Charged with a household outlet, in a vehicle, or via portable solar panels.
  • Capabilities depend on the model and the manufacturer you choose.
  • Some PPS are solar-ready, and some are not.    
  •  PPS don’t charge well in freezing temperatures
  •  PPS are good for power outages, camping, tailgating, or RVing
  • Look for a PPS unit that you can charge and use simultaneously.

5. Small Portable Solar Panels & Chargers

Small solar-powered units are useful for charging smart devices under certain circumstances.

It’s easy to overestimate the charge you will get from small-solar, so test capabilities before you depend on them in an emergency.

Interesting Facts About Small-Solar For Emergency Charging

  • It can take 12 hours of full sunlight to charge a smartphone with a small-solar charging unit.
  • There are 3 hours of “peak sunlight” for solar charging during a sunny day. 
  • Charging electronic devices with solar takes longer than charging with a regular power pack, a generator, or AC outlet.
  • Under optimum conditions, solar provides minimal electrical current.
  • Not the best charging option for snow storms or overcast weather
  • Small-solar panels and solar chargers are not created equal. Do product research before you purchase a device.
  • With small solar, it’s easier to maintain your battery than it is to charge a drained battery

6. Uninterruptible Power Supply (UPS) 

An Uninterruptible Power Supply (UPS) is a device made for computers and used to instantly provide power to critical electronic devices in a power outage.

Why would I use a UPS?

If you live in an area with brownouts, blackouts, or power surges, a UPS is an emergency charging option that works well for critical electronic devices like home computers, laptops, and tablets.

  • UPS is especially useful if you work with critical data that you would need time to save before you lose all power to the device.
  • If you choose a UPS with a large battery, you can get a substantial charge for your smart devices.
  • Has a limited emergency supply of power – just enough time to save documents.

7. Hand-crank Radio Flashlight Combos

I love my hand-crank emergency radio flashlight. It has the ability to charge by solar or by hand cranking. The flashlight works great, and so does the radio. It falls short when it comes to charging smart devices.

  • You will get a full-blown workout in exchange for minutes of battery charge.
  • My hand-crank radio flashlight will not charge my iPhone.

Experiment With My Hand-crank Radio Flashlight:

  1.  With my iPhone turned on, I hooked it up to my inexpensive emergency radio/flashlight combo with a USB charging cord.
  2. I cranked like a madman for 2 minutes.
    1. My phone didn’t charge; the battery charge went down with the phone turned on.
  3. I turned my smartphone off, hooked it back up to the radio and cranked like crazy for two more minutes.
  4. The phone charge increased by 1%.  
  • I’m sure there are better hand-crank chargers out there, but make sure you test whatever device you choose. I would not depend on radio-flashlight combos for emergency smart-device charging without doing some rigorous testing.
  • Radio Flashlight combos are fantastic for the use of the emergency radio and the flashlight.

8. 1000 Watt Inverter Generators: Small Gas Powered Generators  

A gas-powered generator is probably a bigger solution than you need just to power smart devices; it offers a lot more. These generators will power smartphones, laptops, tablets, home computers, portable fans, TVs, coffee makers, blenders, slow cookers, and two-way radios.

I recognize these may not be an option for some. They are pricey, and you need an outdoor area to run them safely.

I can’t attest to the quality of the device, but I was surprised to find that you can purchase the Sportsman’s 1000-watt generator for less than $350.00.

Things to consider when using a gas-powered generator in a power outage:

  • Inverted Generators require fuel, so storage may be an issue
  • Inverted Generators require maintenance
  • Inverted Generators require enough outdoor space to get 20 ft from any openings in a structure.
  • For power, you’ll need to run a heavy-duty outdoor extension cord from the generator into the structure.
