These 5 Things Helped Me Survive 2 Massive Power Outages

I pressed my kid’s frog flashlight into service, but the real lifesaver was a huge battery.

My family was among the 367,000 PG&E customers hit by a massive power outage in the San Francisco Bay Area last week, and now we’ve lost power in a second outage affecting about 90,000 of us. High winds brought down trees and power lines, leaving us without electricity, internet access and heat for exactly 24 hours the first time, and the second outage likely will last even longer.

It sucks.

The outages made me appreciate just how awesome electricity and internet access are, and how critical they are for modern living. Working from home, hearing from schools and the power company, coordinating with my wife — squeezing it all through a woefully insufficient mobile phone network connection.

But a few things helped me through this rough patch. Some of them were pretty high tech, but there’s still a place for pre-internet products in your emergency kit. Here’s what I turned to.

Anker 535 PowerHouse battery

The Anker 535 PowerHouse is one of a host of hulking batteries that, although expensive, is really useful in a power outage. I used it to charge my laptop and phone, to use an LED lamp, and most crucially, to run my broadband modem when I needed my fast network. The display helpfully told me that my network equipment requires 26 watts of power.

The Anker 535 PowerHouse has a bright LED light on its front face along with four USB ports and four power plugs.

During the first outage, I didn’t use the PowerHouse enough. I was trying to husband our resources. But the battery is big enough to power my modem and router for hours.

It’s also got a built-in LED light strip. It’s pretty bright, and I’d have preferred a dimmer option.

This model comes with conventional AC power plugs along with one USB-C port (not enough) and three USB-A ports (too many). You’re better off charging your devices directly from the USB ports if you can: plugging a charger into one of the battery’s power plugs means you’ll suffer efficiency losses converting from direct current to alternating current and back.

Tethering

Connecting my laptop to my phone to take advantage of its mobile network was crucial to getting through the power outages. I’m amazed how much a person can get done with a smartphone these days, but in my case, everything seems to go at least two times slower than with a laptop. Some tasks, like complex photo editing, require a laptop. So for me, tethering is essential.

Unfortunately, the networks my phones use (I have a Google Pixel 7 Pro and an iPhone 14 Pro) aren’t terribly fast, and with so many others’ internet access down during the power outages, I suspect the networks were overtaxed. I remember the crushing feeling when my browser estimated it would take 40 minutes to download a 4.2MB photo file.

Pro tip: On Android, you can tether with a USB-C cable that can be more reliable than Wi-Fi and that keeps the phone charged, too. It works with iPhones and Lightning cables as well. This approach is where the term «tether» came from, of course, but mostly I tether with Wi-Fi these days because it’s simpler and more flexible.

That said, tethering was slow enough that I often preferred to use my phone directly for tasks like email and messaging.

I used the extreme battery saver mode on my Google Pixel 7 Pro to dramatically cut down on its power usage during a power outage.

Phone battery saver modes

I love my phones’ battery saving modes and use them often when I’m at all-day conferences, out on a long hike, or am uncertain when I’ll be able to charge. I long ago customized my iPhone’s Control Center with the low power mode toggle.

I like my Pixel phone’s approach better, where you can set battery saver mode to engage automatically when the battery charge reaches a particular percentage. I have it set to turn on at 60%, but during the first power outage, I just left it on all the time.

Android goes a step farther with extreme battery saver, which shuts down all apps except some core ones and the ones you specify. You can launch anything and use it, but unless you add it to the exceptions list, extreme battery saver will shut it down again. Overnight, my Pixel’s battery charge dropped only 2% during the first power outage.

During the second outage, I just left my phone in extreme battery saver mode almost the entire time, occasionally waking up apps as needed. After a few minutes, the phone puts them back to sleep.

My kid’s frog flashlight and other LED-lit toys

Our kid likes little toys as much as any other elementary school-age child does, and I was delighted when he realized at night that he’d brought home a couple of LED-lit party favors. I’m not sure what to call them, but they have a glowing cylindrical handle with a brush of plastic fiber optic strands sprouting from one end. They’re novelty products but turned out to be handy flashlights, too.

I was happier with another gimmick, though, the frog flashlight we got him at REI to try to cajole him into camping trips. Its carabiner design let me clip it to my belt loop, and it was great for quick lighting at bedtime.

A candle

Candles are millennia-old technology, and you know what? They still work. More than 10 hours into the power outage and with no idea when it might end, I was eager to save any battery power I had left.

I pulled some mushy ice cream out of our not cold enough freezer, lit a candle from our emergency kit and had a late night dessert.

I dripped some wax onto this tomato can to give this candle a safe, sturdy perch.

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
