The brain of this unit is a state of the art microprocessor, fully automated and with a capacity of 12 Amp. It can, therefore, detect a voltage that is either 6 or 12 volts. Moreover, it can do different types of charging – 3 Amp to maintain a charge, 6 Amp for a medium charge, and 12 Amp for a super-fast charge. Few others are quite so efficient on power and friendly to the environment. We are certain that a lot of prospective buyers will be delighted to find that Black & Decker is in the market for battery chargers. After all, with such a diverse reach into the tech industry, some may already have a whole collection of household gadgets exclusively from Black & Decker. What we are really interested in is whether the BM3B is any good. Obviously, charging time is a major talking point for any customer. The battery tender is a 1.25-amp charger and will charge your battery a lot quicker than a 3-amp charger would. In the interests of safety, it features a reverse polarity protection feature.
Knowing your vehicle’s capabilities is therefore very important. Level 2 chargers are sold separately from the car, although they’re often purchased at the same time. These chargers require a slightly more complicated setup, as they are plugged into a 240V outlet which allows charging 3 to 7 times faster depending on the electric car and the charger. All of these chargers have an SAE J1772 connector and are available for online purchase in Canada and the USA. You can learn more about level 2 charging stations in this guide. Ideal for older cars without chargers or outlets in the backseat, this genius car charger plugs into the adapter at the front, then has an almost 5-foot-long cord that passes through to the backseat. Handily, there’s power upfront for the drivers too, with two Type C adapters to plug front-seat devices into. For the backseat, occupants can share between three USB ports to charge devices with. In total, it pumps out a whopping 54 watts of power, meaning there’s enough for everyone to get a little boost.
Before plugging an EV into any outlet, be sure that the circuit does not supply other appliances such as refrigerators or lights. For the connector, nearly all EVs come with a portable Level 1 EVSE cordset, which has a standard three-prong household plug on one end for the outlet and a standard J1772 connectorfor the vehicle. For context, Apple’s official MagSafe charger dishes out 15 watts of power, meaning this one is slower. We still think it’s worth buying, especially since it’s the only MagSafe charger available. In case you’re unfamiliar, the latest iPhones use an array of built-in magnets that allow compatible accessories to seamlessly snap onto the back of an iPhone. Other magnetic mounts require you to stick adhesive magnets to the back of your phone or within a case, but no extra attachments are needed with this charging solution. Instead of setting your phone inside of a claw or a cradle, you stick a small magnet to your phone’s backside or place the magnet in your phone’s case. Then, you just stick it to the magnetic charging pad, and voilà — your phone starts charging.
To decide what products to include, we looked at cost, ease of use, durability, and customer reviews. Prices vary based on the size and features of the battery charger, from about $20 to $250 (though most of the products below fall around $60 or less). Automatic chargers are catching on quite a bit now as they do not require drivers to keeps frequent tabs on the amount of charge the battery is receiving. As soon as the battery is fully charged, they will switch modes to prevent overcharging, thus improving battery life. Also, consider whether the charger can be used to power other electrical items such as your smartphone and laptop. Most individuals travel with several devices in their car at once, from smartphones to e-readers.
The CD-mounted base is similarly simple to slide into the CD slot and lock into place, and it gives you an extra 2 inches of space from your otherwise-ignored CD player. The suction cup on the dash-mounted iOttie stuck almost stubbornly on every surface that we tested, so you won’t need to worry about your phone mount flying out the window when you hit a pothole. This version also has a 4-inch neck that can extend out to 8 inches, so you can position your phone closer to you, if needed. This is particularly handy if you tend to sit farther back from the dash or have a car with a deep, sloping windshield. We evaluated how easy it was to set up the mount on the dash or windshield, attach or remove a phone, and adjust the mount in order to best position the screen. Most wireless charging mounts use a tension-grip design, which holds a phone with two spring-loaded arms on either side; some models also include an additional support underneath. Wireless charging mounts, like the ones we review in this guide, offer the added convenience of charging Qi-compatible phones while you drive.
When it comes to motorcycles, RVs, boats, or any other vehicles that are likely to go long periods of time without use, though, drainage is a major concern. Like cars, these vehicles typically use lead-acid batteries, which experience self-discharge when not in use. It’s recommended that you charge these batteries every 30 days in order to prevent battery death and preserve overall battery health. Of course, like with stored cars, you can also leave these vehicles’ batteries hooked up to automatic chargers or a car battery maintainer. Automatic car battery chargers make the charging process easier by shutting off when your vehicle battery is at 100%, but most of them just aren’t able to charge a dead battery. While manual chargers simply send electricity into a source indiscriminately, automatic chargers need to locate a battery first, and many of them can’t do that with a dead battery. Another feature that makes the Genius1 portable car battery charger useful is the fact that it can charge completely dead batteries. Typically, this is a problem for automatic chargers, but the Genius1 has a “force mode” charging mode that allows it to function as a manual charger. This means that it will deliver a continuous charge that proceeds unabated until you switch it off, and it can be used to resuscitate a battery with zero battery voltage. The more adapters included, the more versatile the portable car battery charger will be.

Level 2 chargers come in a variety of amperages typically ranging from 16 amps to 40 amps. The two most common Level 2 chargers are 16 and 30 amps, which also may be referred to as 3.3 kW and 7.2 kW respectively. These two amperages are the most common because they match the onboard charger on many of the current electric vehicles. The absence of an adapter means an additional purchase is necessary to deliver power to this mount, and the induction technology isn’t guaranteed to work with some older phones and battery types.
Three-stage chargers offer several different modes of charging, from fast charging and top-off charging to trickle charge, which can help maintain a vehicle’s battery in storage. Read through the manual when you first receive your portable car battery charger to familiarize yourself with its main features and operation. You don’t want to be trying to figure out how to use it during an emergency. Portable car battery chargers are generally less expensive than battery jumpers, unless you purchase a unit that combines both. Verify that a portable car battery charger is ETL-certified as meeting safety standards. In addition to emergency lighting, there are some other safety features you should look for in a portable car battery charger.
But we discovered a brilliant little gadget you can retrofit into an old vehicle so it can do both of those things. Amazon has a bunch of high quality USB car chargers, and we found a particularly great one that’s on sale. The Belkin Boostup Wireless Charger was the second-fastest charger that we tested in 2020. However, the spring-loaded side arms were stubborn and difficult to open—which is great for holding your phone steady on the road, but not for attaching or removing it from the mount. We also didn’t like that the mount was permanently attached to its own plug. This made it difficult to put away or use without plugging in, and it also limited the potential charging speed, which is annoying. We were impressed by the Ultimate Wireless Car Charger from Fiora. It’s similar to the iOttie Auto Sense, with auto-locking arms that move just a little more slowly. It also includes all three mounting options—a suction-cup dash or window base, plus a CD-slot and vent mount—in the same box.
We’ve found no less than 15 high-quality designs of car chargers, each one bringing something a little different to the party. Schumacher SC-1200A-CA SpeedCharge 12Amp 6/12V Fully Automatic Battery Charger Microprocessor-controlled battery charger. It does a good job charging batteries, but does not have a jump-start option. Some car chargers handle 6 volt and 12 volt; others work with 12 volt and 24 volt. Ask yourself these questions as you shop for a car battery charger. Once the engine is running, your alternator should supply enough charge to keep things going, but it’s a mistake to think that leaving the motor running will eventually charge the battery. Even running it for a long time will leave your battery in a weakened state. The battery needs a proper charge to put things back to normal. Both these types are also called “wet cell” or “flooded” batteries because they contain liquid .
The charger can handle tablets, too—it produces a whopping 54 watts, after all—and won’t get overheated or short-circuit, thanks to a slew of protections built into the charger. Plus, it’s made to hold up for trip after trip with a sturdy aluminum build. Since many compact laptops charge at 30 W or 45 W, you can even use this Nekteck charger to quickly fill them up on the go. The larger iPad reached 33% charge in half an hour and 65% in one hour. The Nekteck’s 12-watt USB-A port, on the other hand, brought the iPhone to about 44% and 77% in those respective periods of time. Other USB-C car chargers with 18 W output—we tested four others—can charge a phone just as quickly, but few pair that capability with a quality USB-A port, and none do so for such a good price. The Nekteck PD 45W Type-C Car Charger is the right model for any vehicle, any phone, and almost any device you might want to charge while driving. It’s a tiny but powerful charger that has both USB-C and USB-A ports, ensuring near-universal charging compatibility. The Nekteck also comes with a USB-C–to–USB-C cable, making this low-priced model an even better value. There are about 13,000 electric vehicle fast charging stations in the United States, according to data from the US Department of Energy.
Upgrading from your standard home charging station to a level 2 charger will provide faster charging, which in some cases can be up to 5 times quicker. The second type of automatic car battery charger works in a similar way, but you attach it to your car battery and pretty much leave it attached. This type of automatic car battery charger continuously maintains the level of power in your car battery and gives you a reading on the power remaining in your car battery via a display. For homes with multiple cars, you really want a charger that you can use on all the cars in your garage which is why this CTEK (56-353) MULTI US Volt Battery Charger is such a great find. It is a universal fit for most car batteries and it’s fully automatic and super easy to use. It can even help extend the life of your battery making it energy and cost-effective. This car battery charger can restore battery life as well as recondition flat batteries quickly and effectively so keep it close and never be stranded on the side of the road.

There’s an automatic cable winder in the middle that extends and retracts as you pull on each side simultaneously. The Ember Travel Mug2 is the company’s newest way to carry coffee. Unlike its standard Mug2 with no lid, this one is enclosed to avoid spills while moving around. It also features an integrated display to show your personalized name, temperature, and battery level readouts. The first generation Ember Travel Mug does similar tasks, but this second version improves on usability and packs a longer-lasting battery. Older cars without USB charging ports and Bluetooth audio can feel positively archaic these days, but as long as they have a 12V lighter socket and an FM radio, this is a very easy problem to fix.
To ensure you have as long as you need to drink your coffee hot, each mug comes with a saucer-like charger that plugs into the wall. In a similar move to extend battery life indefinitely on the road for both of its travel mugs, Ember now has a car charger. This sub-£15 gadget slots into your lighter socket, then can charge devices from its (admittedly low-power) 2.1A USB ports, and play music from your phone on the car’s stereo. The Bluetooth module is wireless and has a battery life of 10 hours of continuous music streaming. It is then recharged either by plugging into a USB port at home, or by attaching magnetically to the top of the 12V socket charger. Very few cars have wireless charging, but with this phone holder it’s a feature you can easily add to your vehicle for a little over £20. This phone holder works like most others slotting into an air vent then hooking around the back of the outlet’s fins to stay in place. This solution doesn’t work on every type of vent, so check the diagrams carefully before purchasing. Most USB car chargers stick out some way from the 12V lighter socket, but this option from DIVI is much smaller.
