This Mother’s Day Give the Moms in Your Life a Power Boost with the Latest in Portable Power – From Jump Starters to Power Stations

Every mother has superpowers. They can do a dozen things at once, have eyes in the back of their heads, and can cope with any emergency. Moms also seem to have vast stores of energy to get through their seemingly endless list of tasks, responsibilities, and activities. This Mother’s Day give your mother a gift to boost her powers and make her days a bit easier.

Schumacher Electric has a wide array of products to manage an emergency, provide power on the go, and just make life more comfortable when you walk out your door. With Schumacher, mom doesn’t always have to be the hero. We can come to the rescue if she has a roadside emergency, recharge her tablet before book club, and power all her tailgating accessories during a Saturday soccer game.

Your Mom Can Be Her Own Hero

A dead battery can happen to anyone, but for moms it can be especially challenging. Imagine a mom you know with a car full of kids. Then, when she tries to turn on the vehicle, she finds a dead battery. Maybe it’s a hot day or the kids are especially cranky. Or maybe the mom you’re picturing is older and alone in an unsafe location. In these situations, it’s not always practical to wait for a tow truck or a good Samaritan to come to the rescue.

It’s easy to give moms the power to provide their own rescue. Simply gift them a Schumacher SL1648 1250A Rugged Lithium Jump Starter and Portable Power Pack this Mother’s Day. This jump starter features a compact size that fits in most center consoles and glove boxes, along with 1250 amps of jump starting power suitable for up to 6.0L gas and 3.0L diesel engines. It’s easy to use and also features a USB port to charge devices like a cranky toddler’s tablet. With this jump starter, mom will have the peace of mind of knowing a dead battery won’t slow her down for long.

Another option for on-the-go moms is the CRAFTSMAN CMXCESM256 Portable Power Station and 1200 Peak Amp Jump Starter. With this tool, Mom can tackle a range of emergencies and emerge victorious. In addition to a powerful jump starter, the unit also serves as a portable power station, letting mom power a range of devices including smartphones, tablets, and power tools with the 12V DC port, 120V AC household outlet with 200W inverter, and four-port USB hub. Mom can also defeat a flat tire or a deflated beach ball with the built-in 100-PSI automatic air compressor.

With either of these handy tools, mom will be prepared for any roadside emergency that comes her way.

Take Mom’s Seat on the Sidelines Up a Notch

For moms with active children, weekends are often spent on the sidelines cheering their offspring on to victory (or at least a participation trophy). This doesn’t have to mean an uncomfortable camp chair under a blazing hot sun in the summer or shivering from a cold north wind in the winter. With a little help from Schumacher, you can help the moms in your life elevate their tailgating prowess and make their children’s athletic activities something to look forward to.

Compact and lightweight, the Schumacher SL1638 Lithium Ion Portable Power Pack and 800A 12V Jump Starter will make any basketball, football, baseball, or soccer game more comfortable and a lot more fun. With the SL1638, there’s no need to worry about a dying smartphone battery. The unit’s 2.4A USB port lets you charge all of your mobile devices two times faster than a standard USB port. Mom will be able to make it through an all-day tournament with ease.

Moms Don’t Stop When the Sun Goes Down

Unlike solar panels and sundials, mothers don’t quit working when it gets dark. They are still busy, helping with homework, cooking dinner, or shuttling kids between ballet and karate. While moms have tons of superpowers, seeing in the dark isn’t one of them. So, give a mom in your life a little help with the gift of a handy portable area light. The Schumacher SL923 LED Rechargeable Work Light is compact and powerful, easily able to illuminate any area where mom needs to boost the ambient lighting. It’s perfect for emergencies, such as helping complete Timmy’s class project during a power outage or shining a light on the hijinks of Susie’s backyard camp out. And for those times when mom’s smartphone is almost out of juice, the SL923 has a discrete USB output on the back capable of restoring a full charge.

Mom, the Green Warrior

Many moms are becoming green warriors to ensure their children will have a sustainable future. Whether this means solar panels on the roof, organic local produce in the refrigerator, or an electric vehicle in the garage, these moms are committed to saving the planet.

A busy mom will put many miles on the odometer as she runs from ballet lessons to soccer practice to the grocery store. With an EV, a busy Saturday of errands and children’s activities mean mom may have to add a charge to her car while attending a birthday party or while sitting on the sidelines at a soccer game. With the Schumacher SC1455 Level 1 and Level 2 Portable EV Charger, mom can fill up almost anywhere. She can plug her EV into any 120V AC household outlet or 240V NEMA 6-20P outlet and charge up before she heads to her next destination.

The Power of Thank You

Unlike superheroes, moms rarely get accolades or blockbuster films based on their adventures. They don’t have huge fan bases or cosplayers dedicated to replicating the outfit they wore to their last parent-teacher conference. However, you can show the moms close to you that their fan bases, while small, are devoted. This Mother’s Day give her something that will make her life a little easier, give her peace of mind, and show her just how much she is appreciated.

The automotive landscape is in the midst of a revolution, shifting from gasoline-powered to electric vehicles (EVs) at a rapid pace. In fact, EV sales are projected to number nearly 24 million units between 2022 and 2030.[1]  Electric vehicle owners are at the forefront of this change, enthusiastically embracing the automobile of the future. And it’s not just the cars they drive that these forward-thinking motorists want to change. They want their homes to evolve to accommodate their EVs.

One of the advantages of electric vehicles is their ability to “fill up” anywhere the driver can access electricity. However, today’s EV drivers want to go a bit further, installing at-home dedicated EV chargers that allow powerful and rapid charging in the place where they spend most of their time—home. In fact, EV owners, more than 80 percent, overwhelmingly prefer to charge their EV at home.[2] And updating your home to integrate EV charging offers several advantages—faster EV charging, convenience, smart home integration, wireless monitoring, and added home resale value.

By 2030, 52 percent of new vehicle sales will be EVs.[3] That ensures that any investment you make to add EV charging capabilities to your own home will be a smart one. Not only will it add convenience to your life, but it will make your home more attractive to homebuyers who are increasingly likely to be EV owners themselves.

Schumacher Electric’s Range of EV Chargers

Schumacher Electric has delivered innovative and reliable automotive products trusted by professionals and home mechanics for more than 75 years. Our range of Level 1 and Level 2 EV chargers follows this tradition, offering consumers the convenience of portable or at-home charging from a brand they can trust.

EV Series Level 2 Wall Chargers

The Schumacher EV Series is a line of Level 2 EV wall chargers that offers three configurations and the ability to customize the unit for maximum performance. The SEV1600HW is designed to be hardwired into your home’s power system, the SEV1600P650 is compatible with a NEMA 6-50 outlet, and the SEV1600P1450 connects to a NEMA 14-50 outlet.[4] All three models offer you the convenience of charging in your own home or driveway at speeds up to eight times faster than a Level 1 charger. The units are also Made to be Integrated™ with Wi-Fi® and Bluetooth® and can be monitored via the SchuPower™ app or a smart home system. The charging gun for the EV Series has an SAE-J1772 (universal) connector that is compatible with most EVs and an interchangeable dock with dual docking capability.[5] All three models may be installed indoors or outdoors to match your needs and lifestyle. If installed indoors, a low-profile design and built-in cord management with the flexible cable cradle prevent the unit from cluttering up your garage. The 25-foot charging cable allows you to easily charge vehicles parked in your garage or driveway whether your charger is installed indoors or out.

Level 1/Level 2 Portable EV Charger

For on-the-go portable charging, it’s hard to beat the Schumacher SC1455 Level 1/Level 2 Portable EV Charger. The unit offers the flexibility of both Level 1 and Level 2 EV charging, letting you charge up to three times faster than a standard Level 1 charger. To utilize Level 2 EV charging, connect the SC1455 to a 240V NEMA 6-20P plug. For Level 1 charging, use the included adaptor connected to a standard 120V NEMA 5-15 household AC outlet. The charging gun features a universal SAE-J1772 EV connector, which works with most North American EVs.[6] Designed for convenience and ease of use, the SC1455 has an industry-leading 28-foot charging cable, long enough to reach both bays of a two-car garage or from a garage wall plug to the driveway. Other features include an ergonomic design, a rubber cover to protect from water and dirt, built-in LED indicators, and integrated overcurrent and overvoltage protection.

EV Charging Levels

When you decide to add EV charging to your home, you’ll be faced with a range of industry terminology that can be confusing to the standard consumer. The most important terms to understand are the three classifications of EV chargers—Level 1, Level 2, and Level 3.

We’ll start with Level 1 charging. When you purchased your EV, it probably came with a Level 1 charger. These chargers plug into a standard 120V household AC outlet. They require no additional wiring or alterations to your home and are portable, allowing you to take them with you as you travel. However, Level 1 EV chargers offer the slowest rate of charging, usually adding only 3-6 miles of range per hour.

Level 2 chargers may be found in both residential and commercial settings. They have the advantage of allowing much more rapid charging than offered by Level 1 chargers. Level 2 EV chargers typically add 20-60 miles of range per hour, depending on the unit’s specifications, your home’s power system, and the manner of installation. This allows EV owners like you to completely replenish their vehicle’s charge in a few hours. They can easily plug their vehicle in at night and have a full charge when they leave the next morning. And because the average EV owner travels less than 40 miles per day, they can often bring their battery to full in only an hour or two.[7] Level 2 chargers run on 208-240 volts, so they require a licensed electrician to install. They can be hardwired into the electrical system or plugged into a 240V outlet.

Level 3 charging, also known as DC fast charging, is only found in commercial settings. Running on varying high voltages, these chargers can add 60-100 miles of range in just 20 minutes. However, because of their energy requirements, Level 3 chargers are not compatible with standard home power systems.

Ways to Install a Level 2 EV Charger

Before we begin, it should be noted that the installation of a Level 2 charger will in almost all cases require the services of a licensed electrician. In addition, it will probably be worth your while to find an electrician who specializes in or has experience with installing Level 2 EV chargers. The cost and difficulty of your installation will be influenced by several factors, including location, physical obstacles, and your home’s existing power system. For example, a new home with a smart power system will more easily accommodate an at-home Level 2 charger. Older, lower-amperage power systems may need upgrades that will increase the complexity and cost of your installation.

There are three basic ways and two environments to consider when choosing where and how to install your Level 2 charger. First, determine whether you will install the charger indoors, such as inside a garage, or outdoors, such as on a freestanding post or an exterior wall of your home. The Schumacher EV Series models are raintight and water resistant, so they can accommodate either indoor or outdoor installation. Second, determine, perhaps with the advice of an electrician, how your new Level 2 EV charger will connect to your home’s power system. Schumacher offers three installation options—hardwired, plug in with a NEMA 6-50 outlet, and plug in with a NEMA 14-50 outlet.

Hardwired vs. Plug-in

Hardwiring a Schumacher charger into your home’s power system offers a number of advantages. With a hardwired connection you can employ a maximum amperage of 50A. This will allow you to get the fastest possible charging speeds offered by your EV charger and supported by your home’s power system.

Alternatively, installing a 240V outlet in either a NEMA 6-50 or NEMA 14-50 configuration gives you the ability to easily replace the unit in the future or take your wall charger with you if you move. A disadvantage is a lower maximum amperage. The maximum amperage rating for plug-in Level 2 chargers is 40A.

It is worth checking your vehicle’s maximum charging rate before choosing between hardwired and plug-in EV chargers. Some vehicles have a maximum charging rate below 40A, which would mean either hardwired or plug-in EV chargers would offer the same performance.

100A vs 200A Service

The power systems of most new or updated homes today offer 200 amps of service. However, many older homes still have 100A systems. To add an EV charger to a 100A system will either require the homeowner to upgrade the service to 200A, which can cost thousands of dollars or install an energy management device, which monitors power use and will discontinue vehicle charging if the home’s power use approaches its maximum.[8]

Made to be Integrated™

Schumacher’s EV Series Level 2 wall chargers are Made to be Integrated™, which means they are ideal for incorporating into a holistic smart home system. Although your Schumacher charger can be monitored and controlled independently with the SchuPower™ app, thanks to open API, Schumacher chargers can be incorporated into many smart home system interfaces. Wi-Fi and Bluetooth capability make connecting to you home network a breeze.

Life with Your Level 2 EV Charger

Once your Level 2 EV charger installation is complete, you are ready to fully embrace the EV revolution. Your home will be ready for years of home charging. Instead of spending thousands of dollars per year at the gas station, you will be able to economically “fill up” at home and leave the expense, fumes, and inconvenience of the gas pump in your rearview mirror—forever.

How often do you charge your phone? What about your headphones or your computer?  We use numerous devices throughout the day that require charged batteries to function. Vehicles—from cars and trucks to boats and RVs—are no exception.

In many cases, all it takes to keep a vehicle battery charged and functioning is to operate it. Leaving a car or boat to sit idle for months at a time is a recipe for a dead battery. Take the time to regularly keep it juiced up with a Schumacher Electric battery charger.

But, how do you know what kind of battery charger to buy? The answer depends on the type of battery, vehicle, and use case. Some chargers are used for a specific period of time and removed quickly. Others are more forgiving when it comes to battery overcharging. Have questions? You can always refer to your battery’s user manual for more information or contact us if your answer can’t be found in your manual.

Let’s look at some of the common terms related to batteries and battery chargers. Then we’ll talk about options you have for charging your batteries.

Common Terms Related to Batteries and Battery Chargers

Before we talk about the chargers themselves, familiarize yourself with the following terms. Different types of chargers are appropriate for different batteries. Charging speeds can vary based on amperage, voltage, and length of time spent charging:

Battery chargers often have different amperage depending on their purpose. Common charging rates include 2-amp, 10-amp, 12-amp, or 15-amp charge rates. Higher amp ratings will lead to faster charging, but exceeding the recommended rate for your battery could lead to dangerous situations. Always check your battery’s specifications to find the optimal safe charging rate.

Types of Battery Chargers

Schumacher Electric sells many different types of battery chargers. The two most common types we offer are manual battery chargers and automatic battery chargers. These two charger types have key differences in their operation. Follow the instructions to preserve your battery’s life and stay safe.

Manual Battery Chargers

Manual battery chargers charge the battery they’re attached to regardless of the battery’s charge level. They do not cycle or shut down by themselves. Instead, they’ll push current at the selected setting until you disconnect them from the charger.

If you’re using a manual battery charger, keep an eye on the ammeter as you charge. This will ensure you know when full charge is achieved.

You can also use a hydrometer or voltmeter to determine the level of charge. Stop the charging process as soon as the battery is fully charged. Failure to do so could result in battery damage, property damage, and even injury.

Automatic Battery Chargers

Schumacher automatic battery chargers will stop charging and switch to a Maintain Mode (Float-Mode) once the battery is fully charged. Automatic chargers don’t impact battery life or safety as much as manual ones. But they shouldn’t stay connected for indefinite periods of time or as maintenance chargers.

What is maintain mode (float mode) charging?

Maintain mode, also called float mode, charging is a technology used in many Schumacher automatic chargers and maintainers. It keeps batteries charged by delivering small amounts of current to the battery when necessary. If battery voltage drops below a preset level, the charger will begin to charge it once more. It continues to switch between the two modes as necessary. Most Schumacher automatic chargers use microprocessors to help manage the charging process.

How Microprocessor Controlled Charging Works

These differ from chargers with transformers in key ways. Microprocessor controlled chargers use algorithms to monitor the charging process and make adjustments based on the information about the battery’s current voltage and charge.

Fast charging in this way doesn’t negatively affect battery life or performance, and it can even help prolong battery life. The best part about microprocessor controlled chargers is that they can be connected for a longer period of time. For faster, safer, and more efficient charging, use a microprocessor controlled charger.

Trickle Chargers

Another type of maintenance charger can be left attached to a battery for a day or two out of the month. These chargers are called trickle chargers. Unlike float chargers, however, they have no sensor to determine when or if a battery is charged. Like manual chargers, they’ll continue to deliver current until disconnected.

How to Use a Trickle Charger

To use a battery trickle charger, connect it like you would any other battery charger. Use it once per month, and let it run for no longer than a day or two. This will keep your battery adequately charged and maintained without running the risk of boiling the electrolytes out of your battery or damaging its exterior plates through overcharging.

Solar Chargers

Solar chargers draw energy from the sun via solar panels and convert it into usable current to charge your batteries. In many cases, solar chargers may be left installed on vehicles for longer than a day or two.

Despite their ease of use, using a solar charger may result in overcharging. In these cases, a charge controller may be recommended for additional protection from this overcharging process.

Which Battery Charger Should I Buy?

The choice of battery charger depends upon your battery and needs. Buy a trickle charger or manual charger for occasional charging where you’ll be monitoring the battery as it charges. For anything else, an automatic charger gives you powerful flexibility and peace of mind.

Where to Find Battery Chargers
