Product Review: Duracell Digital Inverter 800

  1. Do you live in an area where the power could ever go out?
  2. Do you own a vehicle (or, more accurately, own a vehicle battery)?
  3. Do you have small devices such as cell phones, laptop computers, tablet devices, power tools, or even lamps that you would like to be able to power during a blackout?

inverterIf the answer to all these questions is “yes”, do yourself a favor and spend about $65 and get a Duracell Digital Inverter 800 (or another comparable quality inverter).

How does an inverter work? To review, batteries store DC (direct current) power, while common household devices use AC (alternating current) power. An inverter converts stored DC power to useable AC power (anything with a two/three prong plug).

When people first begin thinking about backup power, they frequently discuss getting a generator. While a generator can be a good step — when it’s an informed decision, and it’s capabilities and limitations are understood. But a generator can be expensive, it takes up space, needs to be maintained, and storing gasoline for it can be a hassle. An easier first step to backup power is a quality inverter. If you already have a generator this adds a second level of redundancy, and might work even better for smaller devices and when you’re on the road.

I first heard about these inverters on The Survival Podcast in an interview with Steven Harris (here’s a list of the many interviews Steven has done on a variety of backup power topics).The Duracell Digital Inverter 800 is convenient and simple to use. It’s relatively compact (7.5” x 4.5” x 2.25”), solidly built, and light weight (1.8 pound). It has a nice LED digital display that shows input and output voltages, making it very easy to oversee and troubleshoot the inverter.

inverter in JeepTo use, connect the inverter directly to your car’s battery terminals (using the DC battery cables with alligator clamps). Then, I’d recommend, run a long 14-gauge extension cord into your house and plug it into a power strip. Plug your devices into the power strip; when you’re not using it, you can turn off the power strip to ensure you’re not inadvertently drawing power to an appliance. Of course you can always plug appliances, or tools, directly into the inverter.

When you’re using the inverter an alarm will sound when your car’s battery gets low, and the inverter will automatically shut off before the battery gets too low; this ensures you’ll never drain your vehicle’s battery further than you should. At that point you can either drive around for a bit, your car’s alternator will recharge your battery, or switch to another vehicle’s battery. For those that have a diesel pickup truck (like our Ford F350) you have TWO batteries, so twice the backup power potential. If you leave your vehicle idling, you can draw full power as long as you have available fuel; this is especially handy for larger devices (the inverter can handle devices that surge up to 1280W). The inverter also has a high voltage shutdown, an overload shutdown, and an overheating shutdown.

There are different size inverters, both higher and lower rated, but the 800 seems to fit the best for most of us. Their 400 is handy because it also comes with a DC lighter adapter allowing you to draw up to 150 watts without having to connect to the battery; very useful for road trips. (Despite what Amazon.com says, the 800 watt inverter does not come with a lighter adapter.)

Having an inverter will allow you–during a power outage, or anytime you’re away from an AC outlet (camping, job sites, etc.)–to convert the DC power stored in your car’s 12-volt battery into 120-volt AC power that you can plug electric devices into.

We tend to take electricity, and our access to it, for granted. When it’s not available our lifestyles quickly change. Having a Duracell Digital Inverter 800 around is an easy step to provide needed power for communication devices, tools, and light when needed.

 

 

Momma Bear’s August Preps

Posted on by

August has been madhouse crazy for us with plenty of work and personal commitments. We have not done as much prepping as I would like. BUT, when we are too busy for physical preps I can always use the time to learn new things. This month’s field of study focused on EMP’s. I found two sites to be particularly informative. The first, The Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack, includes two reports that describe the recommendations for how we should prepare for an EMP strike. It is interesting to read,  because you quickly grasp that this report was essentially poo-poo’d by our government and we remain ridiculously unprepared for such an attack. The second is a website that talks about home-made faraday cages designed to protect small electronic devices. After reading this, my son and I built a small faraday cage out of an old microwave; then placed our small shortwave radio inside.

This month we also made a few purchases. Following Trace and Sarah’s lead, we ordered the Duracell 813-0807 800 Watt DC to AC Digital Power Inverter. For the time being, we have opted not to buy a generator and this will be our interim solution. With three vehicles, we can surely spare one to power some things here at home. My second purchase was a ham radio. We are absolute beginners with ham radios and are not really looking to broadcast (just to receive information from a distance in an emergency), so we opted for a small, inexpensive hand-held model. We ordered the BaoFeng UV-5R 136-174/400-480 MHz Dual-Band DTMF CTCSS DCS FM Ham Two Way Radio, for less than $60. There is a more basic model available, but after reading some reviews we felt this one was a better choice. All that said, even this basic model is a complex item that is going to take some research to understand. Thankfully, there is always the internet and YouTube to answer our questions. And, of course, once we get this thing mastered it will also be going into the faraday cage. Our goal is that eventually all the BOB’s will have either shortwave or ham radios in them as well. I will report back next month on how the ham radio learning is going!

Last for this month, I continue to harvest tomatoes as they ripen and can them as tomatoes, salsa or ketchup. We have finally gotten over the real HEAT of the summer here so the garden isn’t quite so “needy” any more. We currently have green onions, cilantro, and baby spinach coming up in containers. These are probably our most eaten/purchased vegetables so we are really enjoying the fruits of our labor at the moment!

How did your month go, and how’s your garden growing?

What We Did This Week To Prep 8/17/12

After I discovered the ease and convenience of recharging batteries, with our Goal Zero Nomad 7 Solar Panel and Guide 10 Power Pack, I decided we needed to expand out into the world of rechargeable batteries. This was a new thing for me, the rechargeable batteries that I was used to were the old fashioned kind that were expensive, didn’t last long, developed memories, and over-all not worth the hassle. The new kind can be charged over 1500 times and developing memory is no longer an issue.

I also recently learned about this topic on The Survival Podcast when Jack interviewed Steven Harris on Dealing with a Large Scale Blackout. Steven discussed how people could have been better prepared for the recent east coast power outage, and of course any future power outages, in some very simple ways with some very straight-forward products.

Steven Harris is a guru of all things ‘energy’. Yea he’s slightly goofy and tends to ramble a bit, but his knowledge and ability to easily explain the complex world of energy is incredible.

The products that he recommended–not his products, just ones he’s thoroughly tested and provided links to on his site: SOLAR1234.com–that we chose to order were:

  • Powerex Eight Cell Smart Charger (MH-C800S). An 8 AA or AAA battery charger that charges in one to two hours; it also has a large LCD screen showing the status of each battery. This will give us an easy, relatively low energy draw, way to have an almost infinite supply of battery power.
  • Sanyo 1500 eneloop 8 pack AA, and AAA, NiHM Precharged Rechargeable Batteries. (For use with the above charger.) We ordered one of each, Costco also carries these and we can get more there after we test them out. These can also be recharged with our Goal Zero Solar Panel and Power Pack.
  • Duracell 800 Watt DC to AC Digital Power Inverter (813-0807). It runs at 150 watts through your car’s cigarette lighter, or 800 watts when clamped directly to your car’s battery (comes with cables for each method). It has a display that shows: voltage in, voltage out, and watts (power) that you are currently drawing. With this your car becomes an improvised generator and power is stored in your car’s battery (800 watts is enough to power your refrigerator).

And the item we’re most excited about:

  • Trent iTorch IMP52D 52mAh External Battery Charger (for ANYTHING USB). It’s a portable rechargeable lithium battery that holds enough energy to completely charge a dead iPhone 3.5 times! We ordered one for both Sarah and I (and Sarah’s Dad, who happened to be here at the time). We’ve been searching for a product like this to add to our get-home bags (GHB) and this one comes very highly recommended. I plan on thoroughly testing, then reviewing the iTorch.

On another topic, we had to find a way to keep our rabbits cool this week. While I know we won’t get much sympathy from the rest of the country, it actually got hot here in Western Washington. We had temperatures in the mid-90s, which is really hot for us (keep in mind hardly anyone here has air-conditioned homes). To put that temperature in local perspective, I had a co-worker who would say, “Any time it gets above 80 degrees it’s god’s way of showing me what hell would be like.” Yes, the Pacific Northwest is temperate. Anyway with the “hot” temperatures we had to find a way to keep our (Western Washington, not used to the heat) rabbits cool. Sarah did some research and found one of the easiest ways is to put a frozen 2-liter water bottle into each of their hutches and they can lean against it if they get hot. It seemed to work well, the rabbits looked less agitated and seemed to be panting less.

Winter Power Outage = Good Chance To Test Preps

Posted on by

Weathering The Storm 

Western Washington had a pretty good storm last week. I realize, in the larger category of “winter storms”, this wasn’t anywhere among the worst. That being said, it was a big deal around here – we don’t have storms like that very often. What started off as a good amount of snow coming down, transitioned into an ice storm. The tree branches were weighed down and many broke, taking down power lines and causing a power outage that affected close to 300,000 homes.

We were one of those homes, our power was out for about 36 hours. So when life gives you lemons… I figured this was the perfect opportunity to test our preps! At 7:30 am, as Sarah and I were in the Jeep driving back from the train station (the trains were cancelled because of frozen switches), I got the call the power was out. As I drove up to the house, even though I knew the power was off, I still tried to use the garage door opener (habits). First lesson of the power outage: make sure everyone knows how to manually open the garage door.

Since we have had a couple of “lights-out” drills we knew where to start. We:

  1. ‘Fired-up’ the battery bank and, using a volt meter, checked and recorded the starting voltage (12.6 volts).
  2. Ran a 50 foot, 14-gauge extension cord into the house and plugged it into a surge protector for inside use.
  3. Connected another extension cord to the natural gas furnace to run the blower*.
  4. Put a temperature probe inside the deep freezer (in the garage), with one end out so that it could be easily read, and recorded the starting temperature (10 degrees).
  5. Brought lamps, with low energy bulbs, into the main room and plugged them into the surge protector.

The battery bank operated well that day. My parents, visiting from Colorado, were able to appreciated all our preps. My mom was especially grateful to be able to blow dry and curl her hair (before leaving to see more family) – she felt this alone justified all our preparations. We had heat (though we kept it lower than normal, 62 degrees), light, Ryan was able to play Xbox, and we watched a movie after dinner. Every couple of hours we’d check and record the battery voltage and the deep freezer temperature.

However, when we woke up the next morning I realized the heat wasn’t on. I checked the battery bank and it had powered off. Even though it registered plenty of voltage (11.3 volts) the indicator light showed the batteries had gotten too low – this shouldn’t have happened until it reached 10.0 volts. It’s possible this occurred because I had left the inverter plugged into the wall and the line may have surged, but I don’t know for sure. We got out the generator, fired it up, and connected it to the:

  • inverter, to recharge the battery bank. As soon as it was plugged in the inverter began to charge and work again.
  • freezer, even though the temperature was still below 20 degrees.
  • furnace blower, and turned the heat up to 70 degrees.
  • laptop computer and all other rechargeable devices.

Once the generator was running we used our Volcano Grill and percolator to make coffee, then boiled water for oatmeal.

Sarah and I then left for work. The generator ran for about three hours, then Ryan called and told me it had stopped. I assumed it had run out of gas. I had him plug things back into the inverter and continue to power the house from the battery bank (Repetitive & Redundant). That evening the power came back on. We put everything neatly away, ready for the next time.

(Friday: What I Did This Week To Prep including Storm After Action Review)

*Last summer my good friend, fellow prepper, and HVAC/R technician, Rick helped me rewire the line that powers the blower on my natural gas furnace. This allows me to plug the blower into an alternate power supply if needed. Rick has agreed to guest blog for me next Monday (1/30/12), when he’ll write about how you can do this same project yourself, complete with a detailed how-to video.

Last spring, working on our energy category, I bought a used Generac 5000 generator. My goal is to test it each quarter to ensure it still works properly. I especially wanted to be sure this time of year with the cold winter months approaching. So Ryan, his best friend Chanse, and I got it out. It took us a minute, but once we got the choke properly adjusted it fired up. I need to remember next time that the garage (even with the door open) isn’t the place to test it – it’s loud! Though we haven’t used it other than testing, so far I’ve been pleased with it – but I definitely need more experience using it.

Not long after buying the generator, continuing in the energy category, I bought four slightly used AGM deep cycle batteries and a refurbished Magnum inverter/charger. It took me a while to get all the appropriate knowledge and pieces together. But with the help of a couple TSP forum friends (thanks Dan and Rick), and their electrical/alternative energy knowledge, by early summer I had everything wired together and functional. This past week, after it had quietly sat in the garage for a couple months, I finally did my first test of the system. The test was to see how long our 14 cubic foot deep freezer would run (without opening the freezer) on the batteries. The battery bank, fully charged, started at 12.60 volts. I recorded the time and battery voltage several times a day. It ran for a about 100 hours, until the batteries were at 10.71 volts. A few days after my test I realized that the breaker from the batteries to the inverter had tripped and, after looking at the manual, I determined that the batteries probably should have discharged to 10.50 volts before the inverter tripped off; so add a few more hours to the total. I need to do more testing and develop a better understanding of my backup electric system, but it was a start. Next I’ll do a ‘lights out’ test and see how the battery bank does running some electrical appliances in the house. I also need to use the generator to recharge the discharged battery bank and see how long, and how much gas, that takes.

Ryan & Brynn with our combined order

Lastly, we went to the Mormon Family Home Storage Center (cannery) and canned food to add to our LTS. I previously posted about the Mormon canneries, and included a link to a video of the process, in Long Term Storage (Food Part 2). The staff (Mormon volunteers) were super friendly and helpful. The cannery is scheduled by groups; you can form your own group (Mormon or non-Mormon), or you can be added to a smaller group (we were added to a Mormon group from the Auburn area). A friend had planned to go with me but was unable to go that week, so I offered to do his order as well. Since it was going to be a large order (combined 91 cans) I brought Ryan and Brynn along to help. In addition to us, there were about eight other people in our group. We had each previously submitted our order forms, and all the bulk storage bags we would need had been pulled from the shelves and were ready to go. Start to finish, including orientation and cleanup, took just over two hours. We were assigned a task and, assembly line style, the process started: opening bulk bags, pouring into #10 cans, sealing the metal lid on the can, adding a label, and placing the can in a box for the appropriate order. When all the work was completed, we inventoried and paid for our order. We added 55 #10 cans to our LTS.
