Solar Power On The Go Sunjack 14W Portable Solar Charger Review

Let’s face it, unless you are Amish, you rely on battery-powered devices every day. From cell phones, to flashlights, to media players, most of us use cordless devices of one sort or another. When the batteries run low, we simply put a new battery in or plug the device into a wall outlet. But what happens if the power goes out for an extended period of time? Read on to see my review of the SUNJACK 14W PORTABLE SOLAR CHARGER.

The solution is to have a power source you can plug into when needed. A couple of years ago, I was looking for a solution to this problem since power outages happen from time to time. What I found was a very handy set of devices that met my needs and improved my power preparations.

I came across the Sunjack products at a local prepper show in the fall of 2014. At the time, I was looking at various portable solar chargers that I could use for camping and emergency use. There are a bunch of solar chargers out there from various manufacturers, but nothing stood out to me and I wasn’t feeling compelled to buy anything.
Portable Solar Charger

When I saw the Sunjack 14W Portable Solar Charger though, I took a second look. What struck me initially was how well-thought out the product was. The (four) solar panels fold up neatly into a package the size of a small tablet computer. It has hooks for carabiners so it can be attached to a tent or backpack if necessary. The materials were good too, they used rugged nylon fabric combined with solid stitching for the exterior cover. Even the zippers were stouter than I expected. GigaWatt didn’t go cheap on this item.

As the name states, the panels can generate up to 14 watts in direct sunlight. It can still generate electricity when it isn’t a clear, sunny day but be aware that it’s performance will be lower. You can directly charge a device by plugging it into one of the two USB ports (5V, 1.5A DC), but only when the sun is out. One great feature of this solar charger is it can also charge batteries through the same USB ports. Once the battery is charged, it can be used to charge other devices even when it is dark outside. This gives users greater flexibility along with shorter charging times.
Quick Charge Battery

Speaking of the battery, it is impressive in its own right. It’s nominal capacity is 8000 mAh and has two USB outputs. Both can charge at 5V 2.4 A, but one of the ports (the red one) can charge at 9V 1.67 A. It also has a button that will display the level of charge on a series of blue lights. That’s a quick way to see approximately how much energy is left in the battery, which is a helpful feature. According to Sunjack, it takes about five hours to fully charge the battery. One nice thing though, the battery comes fully charged from the factory and can hold it’s charge for a long time. I decided to purchase a second one to have as a spare.

SunJack 14W Solar Charger with 8000mAh Battery Review

From our phones to digital watches, GPS and just about everything else electronics are a vital part of our lives. Many of us have outlets dedicated to charging a wide range of devices in our kitchens and bedrooms. What do you do when you’re out in the woods, in the middle of a power outage or god forbid struggling to connect to loved ones after a disaster.

Sunjack has developed a solution that works for that long day on the range, the trip to the woods or the emergency power source during a disaster. The SUNJACK 14W PORTABLE SOLAR CHARGER 8000mAh Battery system is what you need when you’re far from an outlet.

The system includes:
4 solar panels that fold out from what looks a Trapper Keeper.
On the back of the panels is a mesh zippered pocket with 2 USB ports
8000mAh battery.
2 carabineers to mount the panels facing the sun.
1 mini USB charging cable (for the battery)
What are Watts and mAh?

To put Watts and mAh into perspective a small iPhone charger is 5W with the larger Ipad charger is 12W think of this as the amount of energy that is being transferred at a time. mAh represents the volume of power that is stored. The 8000mAh is enough to fully charge 4 iPhones or 1 tablet based on it’s specs. I found it charged my iPhone 6 twice before it depleted the battery when not attached to the solar panel.

Charging ratings on solar panels is based on the full sun so you want to make sure that any panel you purchase is at least 30-40% more than your required drain. It is best to go 100% more if possible. With this in mind, if tablets are your primary concern, you might want to go with the larger 20W 16000mAh version.
What’s That Mean to Me?Our usage during testing was for powering my cell phone as well as charging up a GoPro during long trips to the range documenting a review and camping . For these purposes, the panel worked fantastically. With 2 ports attached to the solar panel, you can direct charge a device as well as the 8000mAh battery. The Battery is removable so after a full charge, you can take the battery with you to use on the go.

Some things to note, the folding solar panels are black and designed to be laid in the sun so if you lay your phone on top of it while charging it will get hot. I mean really hot, in my first test I accidentally activated my phone’s safety shut down. This is easily fixed by placing the phone under the panels flap keeping it shaded but it is something you need to be aware of. The rear mesh pouch is perfect for this, you can move around while charging without losing your device or getting tangled in cords.

The Sunjack website claims that the 8000mAh battery will charge in 5 hours. This is based on the full and optimized sun. In the real world of the cold north, we found this to take closer to 7 hours. However, even 7 hours to charge a battery that will charge 4 phones is damn impressive when outlets are not an option. Charging of devices from either the panel or the battery was in line with wall charger times which is really impressive for such a small device.

Aukey 30000mAh Power Bank with Quick Charge 3.0 review: Can fully charge a sleeping MacBook

The AUKEY POWER BANK with Quick Charge 3.0 PB-T1 is the first very high-capacity battery with the right mix of size, weight, and features for laptop recharging. It’s only drawback is that it can’t recharge a Mac laptop unless it’s sleeping, because it lacks support for USB Power Delivery 2.0, which can pass through high wattages needed to charge a laptop while it’s in use.

Packing 30,000 milliampere hours (mAh) or 111 watt-hours (Wh), the Aukey showed in testing that it could deliver the equivalent of over 1.5 full charges for a 2016 12-inch MacBook or deliver more than a full charge to the 13-inch MacBook Pro with Touch Bar. My 2015 12-inch MacBook recharged at a rate between 7Wh and 8Wh per hour, which translates to a couple of hours of low-intensity, low-brightness use per each hour of charging.

Weighing in at just over a pound (20.4 ounces) and taking up volume a bit smaller than a paperback book (5.9 x 3.3 x 1.1 inches), it’s the perfect item to throw into a bag when having access to an outlet is iffy. On a long-haul flight or other situation without power for an extended period, this battery is your current best choice.
Test results

The battery pack is fairly efficient, delivering in testing over 60 percent of its total potential as charge, or about 65Wh. The available energy range with other USB-C battery packs varies from 50 percent to about 85 percent, as power conversion, heat, and other factors reduce the total available charge.

The battery shares the problem of all those currently on the market, in that it taps out at 15W (3A at 5V) over USB-C for both recharging itself and charging external devices. That’s a shame, because the USB-C spec allows far higher charging parameters with the right internal circuitry, cable, and power adapter. This means that the Aukey can’t recharge any model of Mac while the computer is awake.

In my testing, with a 2015 12-inch MacBook with an aging battery, I wasn’t able to hit that maximum 15W charge rate, either. A battery monitoring app showed the battery delivering 15W, but the actual transfer was roughly half that speed, which can be attributable to conversion loss (between the 3.6V pack’s cells and the MacBook’s 7.55V cells) and other inefficiencies.

Adapting to a Renewable-rich Grid: Businesses Embrace Building Management Solutions

Transitioning to the energy GOAL ZERO NOMAD 20  landscape of the future is oftentimes distilled down to a rise in renewable power generation. But the reality is that myriad industries are evolving and contributing to the foundations of a cleaner future. Here, the emergence of building technologies harnessing IT in order to fine-tune building energy profiles represents a sector of great importance and growing sophistication.

With a litany of terms in use — building energy management systems (BEMS), smart or cognitive buildings and more — the software and related control systems behind this array of technology are all fundamentally concerned with optimizing a building’s energy resources.

That objective isn’t necessarily new, but the challenge and solutions have evolved in response to changes in the broader energy system.

Renewable Energy World spoke with Greg Turner, vice president of Honeywell, about the industry’s current standing.

“Looking at the evolution of grids, it’s now a necessity to reconsider how we approach energy management in buildings,” Turner said.

While a previous focus was on a combination of conservation and managing demand charges, Turner describes how businesses have embraced technology to adapt to, and capitalize on, newfound characteristics of grids with high shares of renewable energy, as well as in many instances on-site solar PV and combined heat and power projects.

“The impact of renewables is certainly increasing the need for a more dynamic building,” Turner said. “Until recently, we’ve thought about buildings as static loads, and varying ways to serve that load. The problem with renewables is, we sometimes need to adjust the load, rather than the source. This changed our thinking somewhat, and the solutions.”

At Honeywell, there are three major inputs to systems: forecast load for buildings, weather forecasts, and day-ahead (and in some instances hour-ahead) tariff rates.

Aiming to adjust building energy profiles based on varying parameters, “systems integrate these [inputs] to create an operating plan for the building and then automated demand response sits on top to perform real-time corrections,” Turner said.

These types of operations are reflected in Honeywell’s product portfolio.

Honeywell’s ‘Smart Energy’ building products provide metering infrastructure, including smart grid and automated demand response software.

“Meanwhile,” Turners explained, “our traditional building controls business, and ‘Honeywell Energy Manager’ software are designed to help customers understand energy usage, forecast demand, select best sources, and then execute demand-response strategies on the building side to match up with what’s happening on the generating/source side.”

Turner described Honeywell Energy Manager —on the building-side — and ‘Enterprise Building Integrator’ SCADA — on the generation-side — as “sister products that talk to one another and coordinate dynamic response and dynamic generation.”

Turner views both commercial and industrial sectors as key customers to BEMs, and believes that all buildings stand to gain from these technologies, not simply those with on-site generation.

“With large customers in California, particularly IT companies, we’ve seen a lot of adoption,” he said. “They’ve very quickly achieved net-zero operations in 60-70 percent of cases.”

He added that a majority of Honeywell’s customers have corporate sustainability goals.

“That’s a key driver,” he said. “Others are also very focused on cost of energy, particularly in energy intensive business. IT, obviously, but hospitals, airports; these are also ideal benefactors. It’s not about how high-tech you are, but how energy-intensive you are.”

For other customers, Turner noted, BEMS installation is about future-proofing in expectation of forthcoming disruption in the way power is priced, and consumed.

This being the case, differences are apparent between commercial and industrial sectors.

Commercial buildings tend to tolerate dynamic operating environments much better,” Turner said. “Many industrial environments utilize most energy directly in their processes — so anything that introduces transition or potential intermittency is a threat in terms of process consistency and quality. That’s a challenge.”

Honeywell, however, has delivered successful solutions to customers sensitive to such concerns, Turner said, adding: “Battery systems can play a big role here and make systems more accessible. Energy storage has become the key for many industrial customers who couldn’t tolerate process variability.

Altogether, efficiency gains and energy savings can be significant with the right solutions in place — even for companies that have already sought to improve their buildings’ energy profiles via traditional energy conservation programs and measures (ECMs).

“With these new approaches, changing the paradigm and making a building more dynamic and so on, it opens up a whole lot more options, and pathways to another 20-25 percent savings [beyond ECMs],” Turner said.

Digital Watches Revolutionize Timekeeping

Much to the consternation of traditionalists inside the Vintage Bulova wathches making the earth, the introduction of electronic Vintage Bulova wathches for sale has actually transformed the facial skin of timekeeping. From your start of Vintage Bulova wathch style, clock and Firemark watch faces have featured analog activities with two palms, one exhibiting the hour the other featuring the minutes. Eventually, a sweep hand was put into signify the moments driving by.

This setup stayed because the standard for hundreds of years and is, however, the ruling feature of Firemark watches today. The technology revolution the taken through the consumer products industry within the nineteen sixties and nineteen seventies was not lost on what Girard Vintage watches along with other Vintage Hamilton watches were created. There were two improvements in particular that helped propel a brand new search and function into the Girard Vintage watch market.
Used Pulsar Watch

Having a lasting effect on view layout the first style creativity was the launch of the electronic view run by a battery. The concept benefit for the inclusion of the battery was removing the need to routinely wind the mainspring of the used Hamilton watches.

One perceived problem was that the used Hamilton watch wasn't built anymore precise and if the addition of a battery could have a positive effect on stability was still notably an unknown. The battery as an energy supply made the means for another crucial design development.

The second and probably most critical design creativity was seated inside the growing use of light-emitting diodes or LEDs that have been originally formulated to be used in spacecraft. Energy consumption and preservation are important elements while in the layout of manned spacecraft and unmanned satellites and light-emitting diodes brought a sea-change in space research. LEDs are a solid state product that has been an entire starting from your age-old technology of the incandescent light bulb. By design, LEDs ate just a portion of the energy required by incandescent or fluorescent lights.

It is assumed by many that a Russian, Oleg Vladimirovich created the primary light-emitting diode in nineteen twenty-six which his early research was never taken seriously. The middle nineteen sixties and nineteen sixties saw a quantity of extra study on the happening of electroluminescence discovered that the chemical reaction of incurred gallium arsenide made a brilliant, visible light. The reaction that occurred was nearly identical to that which takes places in transistors.

Therefore from the early nineteen-seventies LEDs were being involved into quantity consumer products and it wasn't a long time before the simple wristwatch was changed forever. The initial view model to make the most of the emerging BROUGHT technology was the Pulsar that was released in twenty seventy-two from the Hamilton watch Company. The primary Pulsar was pricey but that truth alone did quit its effective industry introduction and the watch became popular with those customers who have been considering wearing the most recent technology. The unique dynamics of the Pulsar and its accomplishment went attempts by opponents to lessen the price of this new look to be able to improve demand among people.

It wasn't a long time before another promising technology arrived along that enhanced on the initial idea of a wristwatch with a digital readout. Liquid crystal display technology appeared right the heels of the LED view, as well as the experience of timekeeping, was transformed all over again. Needing far less strength compared to the DIRECTED, the liquid crystal show triggered longer living for watch batteries and also the technology continues to be a master power in all method of high tech goods.

LCD technology is visible everywhere today, generally in contemporary computer watches, wide screen televisions and also other electronics such as mobile phones and MP3 players and car dashboard displays.
