These days, we're glued to our smartphones and tablets, but unfortunately it's hard to make sure they're always juiced up, so portable USB chargers have become a necessity. And, fortunately, there are a bunch of excellent inexpensive car chargers available that can be used for multiple purposes. For example, say the whole family needs a charge on a road trip? No problem. And if you need to give some extra juice to backseat riders? No sweat. Read on to find the top car chargers you need to make sure your phone never runs out of battery. When it comes to charging your smartphone (or other electronic gadgets) in your car, look no further than the Scosche reVOLT. The compact size supports two USB 2.4A (12W) of power, which offers enough power to charge two full-sized tablets at once. The higher output also means you’ll get a slightly faster charge over standard car chargers. The Scosche measures just under 2 inches and is slightly smaller than the height of a credit card. If we had to offer any gripes about this model, it would actually be one that is reserved for all car chargers, regardless of price or manufacturer, one-way insertion. Unlike Apple’s lightning charger, standard USB ports still only accept cables in one direction. It’s a frustration, but given how widespread this is, it’s hardly a deal breaker. Although a good number of cars being produced today offer USB integration, the charging speed of a vehicle charger only offers about 1 amp of output, which is not enough to keep up with a modern-day smartphone trickling out battery life while using Apple or Google maps. In this scenario, you’re likely going to end up at your destination with a battery that was less charged than when you started. At just .8 ounces, the Scosche offers a product that will charge your smartphone at the same speed as your wall charger. The inexpensive price, trusted name, small frame and glowing blue ports that make it simple to plug in when dark make the Scosche an easy recommendation for our top pick.

How can I tell if my battery is charged or not? The simplest method is to test your battery with a voltmeter to measure the voltage between the positive and negative terminals or posts. While the battery is not being charged and not powering anything, you can use your voltmeter and get a reading. For a 12-volt lead-acid battery, the voltage should be between 11 and 13 volts. The closer it is to 13 volts, the closer it is to being fully charged. If it's closer to 11 volts, the battery needs recharged. The exact voltage will differ depending on the battery voltage, style, and age. How long will it take to charge my battery? There's no definitive answer to this question, but you can make a pretty good guess with some simple math. (Battery Capacity) / (Charger Amps) = Hours Our ETX-30L Big Crank battery has a capacity of 26 Ah. You plan on charging this with a 2 amp charger. Using the above equation, you would have [26 Ah / 2 Amp = 13 Hours]. This is a rough estimate and usually tells us how long it will take to recharge the battery to about 80% of its capacity. To complete the recharge all the way to 100%, it will probably take an equal amount of time to recharge the last 20% of capacity. Some chargers may get it there a little faster, but there's no absolute guarantee. Why should I use an automatic charger? The short answer: Overcharging batteries can kill them. If you leave a manual charger connected continuously, even at low amps, the battery will eventually die. When a battery gets overcharged, the electrolyte inside gets hot and gasses are created. If you have an older vented battery, the electrolyte could evaporate and your battery plates will be exposed and eventually ruined. Overcharging a sealed battery will cause the gasses to build up, until the battery balloons out and bursts. An automatic charger will only charge the battery as necessary, shutting itself off until the battery voltage drops again. Great chargers from brands like BatteryMINDer and Battery Tender can keep a battery charged without the risk of damage.

“Through market research and interviews, we found consumers feel anxiety and worry when their battery life is low.” Story of our lives, Tylt. Story of our lives. It gets so bad at times it’s like watching a 4am infomercial about insomnia. Do you feel anxious about not being able to post that last picture on Instagram? Stress about not getting the late night party text that will save you from the crappy party you went to out obligation? Worried that you won’t be able to find your way home without Apple Maps? If you answered yes to any of these questions, and you have a car, Tylt Band is for you! All kidding aside, this is the first car charger we’ve seen that doesn’t appear to suck. It’s a two foot ribbon cable with a car charger on one end and an Apple 30-pin or micro USB connector on the other. There’s also a universal USB port on the car end in case you need to ride the lightning in addition to charging your iPad.

Oddly enough this happened to me yesterday on a trip. Was the battery low when this happened? The connector is a Mini-USB series B connector which has five pins. What I imagine is happening (maybe) is that normally only Pins 1 and Pins 4(and 5, connected to Pin 4) would have voltage, as these babies would be the power in and out. Pin 2 and pin3 would be data, and if any voltage detected on these pins, the device would go into usb mode. So maybe it's dust or some kind of crossover? Is the charger you have definitely transmitting 5V? Your car electrics ok? I can't see your car could be the issue. Although try another car I guess. Then ditch the old one if needed. What I did was to turn it off and leave it to charge for a half hour, then plug it in and pray. Mind you that was after repeatedly plugging the charger in and out of the lighter socket several times. Maybe a blast of compressed air over the mini-usb end of the cable might clear dust out of it. Saying that I can't say that'll fix it. Would it be an issue with the Navman end of the usb plug? The navman should be detected as a hard drive, however the Smartst2008 should detect the device through it's API and it can do it's magic. If this is not the case, have you tried uninstalling and re-installing the original software supplied with the unit? Could be the drivers maybe.

Lately, smartphones are becoming an integral part of our daily lives and it is important that our device’s battery offers us enough juice for longer hours of usage. That’s where a portable charger plays its important role and Nokia has unveiled a wireless car charger for its Lumia 920 smartphones, which should help its consumers enjoy that extra liberty of usage when they are on the go. Nokia’s wireless car charger comes with NFC built-in and is designed like a Nokia car phone holder. Aside from the obvious benefit of the wireless charging, the NFC functionality will allow you to start a specific app or turn on specific car mode setting on your smartphone just by placing it on the stand. The wireless stand is rotatable and you can place your smartphone horizontally too. Unfortunately, there is no information on the pricing and the availability of the charger, but we expect it to bear a hefty price for all that functionality. A peculiar thing to note is that Nokia is advertizing it as a Nokia Lumia 920 wireless charger, but the Lumia 920 is not their only phone with wireless charging.

Advertisement Power to go—aren't batteries brilliant? The trouble is, they store only a fixed amount of electric charge before running flat, usually at the most inconvenient of times. If you use rechargeable batteries, that's less of a problem: click your batteries in the charger, plug in, and in a few hours they're as good as new and ready to use again. A typical rechargeable battery can be charged up hundreds of times, may last you anything from three or four years to a decade or more, and will probably save you hundreds of dollars in buying disposables (so it's brilliant for the environment too). But exactly how well your batteries perform depends on how you use them and how carefully you charge them. That's why a decent battery charger is as important as the batteries you put into it. What is a battery charger and how does it work? Let's take a closer look! Photo: This "fast-charge" battery charger is designed to charge four cylindrical nickel-cadmium (nicad) batteries in five hours or one square-shaped RX22 battery in 16 hours. It's easy to use, and just as easy to misuse: it doesn't switch off when the batteries are fully charged and there's nothing to tell you when charging is complete. With a battery charger like this, charging your batteries is complete guesswork. What are batteries and how do they work? If you've read our main article on batteries, you'll know all about these portable power plants. An example of what scientists refer to as electrochemistry, they use the power of chemistry to release stored electricity very gradually. What happens inside a typical battery—like the one in a flashlight? When you click the power switch, you're giving the green light to chemical reactions inside the battery. As the current starts flowing, the cells (power-generating compartments) inside the battery begin to transform themselves in startling but entirely invisible ways. The chemicals from which their components are made begin to rearrange themselves. Inside each cell, chemical reactions take place involving the two electrical terminals (or electrodes) and a chemical known as the electrolyte that separate them. These chemical reactions cause electrons (the tiny particles inside atoms that carry electricity) to pump around the circuit the battery is connected to, providing power to the flashlight. But the cells inside a battery contain only limited supplies of chemicals so the reactions cannot continue indefinitely. Once the chemicals are depleted, the reactions stop, the electrons cease flowing through the outer circuit, the battery is effectively flat—and your lamp goes out. That's the bad news. The good news is that if you're using a rechargeable battery, you can make the chemical reactions run in reverse using a battery charger. Charging up a battery is the exact opposite of discharging it: where discharging gives out energy, charging takes energy in and stores it by resetting the battery chemicals to how they were originally. In theory, you can charge and discharge a rechargeable battery any number of times; in practice, even rechargeable batteries degrade over time and there eventually comes a point where they're no longer willing to store charge. At that point, you have to recycle them or throw them away. Photo: Ordinary batteries (like this everyday zinc-carbon battery) are not designed to be used more than once—so don't attempt to recharge them. If you don't like zinc carbon batteries, don't start trying to recharge them: buy rechargeable ones to begin with. How battery chargers work All battery chargers have one thing in common: they work by feeding an electric current through batteries for a period of time in the hope that the cells inside will hold on to some of the energy passing through them. That's roughly where the similarity between chargers begins and ends! The cheapest, crudest chargers use either a constant voltage or constant current and apply that to the batteries until you switch them off. Forget, and you'll overcharge the batteries; take the charger off too soon and you won't charge them enough, so they'll run flat more quickly. Better chargers use a much lower, gentler "trickle" charge (maybe 3–5 percent of the battery's maximum rated current) for a much longer period of time. Batteries are a bit like suitcases: the more you pack in, the harder it is to pack in any more—and the longer it takes. That's easy to understand if you remember that charging a battery essentially involves reversing the chemical reactions that take place when it discharges. In a laptop battery, for example, charging and discharging involve shunting lithium ions (atoms missing electrons) back and forth, from one electrode (where there are many of them) to another electrode (where there are few). Since the ions all carry a positive charge, it's easier to move them to the "empty" electrode at the start. As they start to build up there, it gets harder to pack more of them in, making the later stages of charging harder work than the earlier ones. Graph: Batteries get harder to charge in the later stages. It can take as long to charge the last 25 percent of a battery (orange area) as the first 75 percent (yellow area). Overcharging is generally worse than undercharging. If batteries are fully charged and you don't switch off the charger, they'll have to get rid of the extra energy you're feeding in to them. They do that by heating up and building up pressure inside, which can make them rupture, leak chemicals or gas, and even explode. (Think of overcharging as overcooking a battery and you might just remember not to do it!) Slightly more sophisticated timer chargers switch themselves off after a set period, though that doesn't necessarily prevent overcharging or undercharging because the ideal charging time varies for all sorts of reasons (how much charge the battery held to begin with, how hot it is, how old it is, whether one cell is performing better than others, and so on). The best chargers work intelligently, using microchip-based electronic circuits to sense how much charge is stored in the batteries, figuring out from such things as changes in the battery voltage (technically called delta V or ΔV) and cell temperature (delta T or ΔT) when the charging is likely to be "done, " and then switching off the current or changing to a low trickle charge at the appropriate time; in theory, it's impossible to overcharge with an intelligent charger. Photo: Left: The Innovations Battery Manager, popular in the 1990s, was sold as an intelligent battery charger capable of recharging even ordinary zinc-carbon and alkaline batteries. Right: A digital display showed the voltage of each battery as it charged (in this case, 1.39 volts). After charging, a little bar graph appeared showing how good a condition the battery was in (how many more times you could charge it). Many thousands of these chargers were sold, but there were differing opinions on how well they worked. Charging different kinds of rechargeable batteries To complicate matters, different types of rechargeable batteries respond best to different types of charging, so a charger suitable for one type of battery may not work well with another.

Leave the headlights on all night again? No problem. Dead batteries happen, and with these simple steps you can safely recharge your DieHard battery and be back on the road in no time. Position a working vehicle facing your car so the two batteries are as close as possible without the bumpers touching. Turn off the engine, set the parking brake and pop the hood on both cars. Don't have another working vehicle close by? DieHard Portable Power can jumpstart almost any vehicle in an emergency. Follow directions specific to your portable power device. Grab your DieHard booster cables or jumper cables and connect one of the positive cable clamps to the positive post on your drained battery. Attach the other positive clamp to the positive post on the charged battery. Connect the negative DieHard booster cable clamp to the negative post on the charged battery and place the other end of the cable on an exposed piece of metal on the engine of the disabled car to ground it. Start the working vehicle and wait for at least five minutes. Attempt to start the car with the drained battery and if it hesitates, give it another five minutes. Repeat until car starts. Remove the DieHard booster cables from the batteries in the reverse order in which you attached them. Detach the negative cable clamp from the engine and the other end from the negative post on the charged battery. Then remove the positive cable clamp from the charged battery and unhook the positive cable clamp from the once drained battery.
