System software again handles communication with a USB host and sends commands to the charger. The MAX8394 manages the hardware aspects of charging and provides simple hooks for setting charge parameters relevant to USB and adapter charging. USB input current limits are preset to ensure that specified limits are not exceeded; a user-set current is used for adapters. The charger also supplies a complete set of status and fault signals to the system. A dual-input charger like the MAX8844 handles charging from both USB and adapter sources. This device also protects against input overvoltages up to 28V. BC1.1 describes hardware detection methods to determine port type.
Additionally, it’s equipped with a good ol’ USB-A port for recharging gadgets like your headphones that may still use a standard USB cable. Not only is this charger super fast, but it’s also ultra portable. It has foldable prongs, weighs just 3 ounces, and at 2×2 inches, it’s small enough to fit in the palm of your hand. When shopping for a portable charger, versatility matters. The Omnia Mix charger gives users the best of both worlds. It has a USB-C Power Delivery port that, when used on its own, can provide you with an impressive 65 watts of power — enough oomph to recharge a 15-inch laptop at max speed. Of course, it can fast-charge a tablet, smartphone, or a Nintendo Switch, too. The cable that plugs into the Micro USB 2.0 socket on this smartphone has a Type A plug at the other end for the computer or AC charger.
The great thing about solar power banks is that you can charge the power bank throughout the day and then use that to charge your phone at night or on rainy days when there isn’t enough sun. The only downside is that the electricity from the solar panels has to go through the battery before going to your phone. This means that if you let the battery run out completely, you will not be able to charge your phone until you have given the battery time to recharge. Why spend money on a device that can only be used one way when you can choose a device with versatility? That’s why we chose chargers that you would be able to use every day. You can take them on long hiking trips or simply use them at home to take advantage of free solar power, whatever works for you. The high-efficiency solar panels are designed to be water and dust-proof and the ports are protected by a waterproof cover. This charger is also designed to protect your electronics from overcharging, overheating, and short-circuiting, providing a worry-free charging experience. We’ve researched and tested the fastest chargers available and collected our recommendations of the best ones, no matter what device you need to charge. RAVPower’s PD Pioneer 20W Wall Charger (RP-PC149) offers the same power output as our top picks, and is almost exactly the same size and shape.
Read on to find out which one can do the best job of keeping your devices charged up and ready to go. The popularity of the type C charger is rising in the USB charger market due to the launch of advanced products with power delivery functions. The different types of USB chargers are USB wall chargers, USB car chargers, and portable power banks/docking systems/alarm clocks. Analyzing the demand for fast charging speeds and high charging efficiency, manufacturers are launching their own type C charger models with advanced features. For instance, Huntkey, a leading power solution provider, is developing a new model of portable 90W type C for overseas markets. Apart from superlative charging efficiency and best-in-class quality, the portable design is a key USP of this new product launch by Huntkey. In addition, manufacturers are also working on offering space-efficient and heat-resistant designs of USB chargers, with the sole objective of scaling up their product positioning. Companies in the USB charger market are also investing in supplier-retailer relationships that go beyond ‘day-to-day’ business transactions, and promise long-term profitability for both the parties.
The proliferation of smartphones and tablets indicates that a typical person might need to charge three or four devices at once, due to current usage patterns. Using a separate charger for each device means taking up valuable outlet space. With a USB lead, you can connect to a desktop or laptop and draw power via yourcomputer power adapter cable. USB ports can only pass 500 milliamps of power at a time, and wall outlets can pass 2 Amps. With a multi-port charging station, you can charge four or more devices using a single USB wall charger, and enjoy faster charge times. The RAVPower 30W Dual Port Compact PD Charger (RP-PC132) is the best dual-port charger for getting the maximum charging speed on your phone no matter what cable you use. It provides both a 12-watt USB-A port and an 18-watt USB-C port, so you can charge your phone two to three times faster than with the charger that came in the box with your phone.
I’ve been using it for more than a year almost daily traveling and at home, and it’s as good as new. Plugable’s $26 Thunderbolt/USB-C cable may be shorter at 2.6 feet (0.8 meters) than some you’re used to, but along side charging it can transfer data at a whopping 40 gigabits per second. It’s a supple, durable cable that’s served me well for more than a year of daily use. If the sample will be made according to your drawing or specification, you have to pay the tooling charge.

Most portable laptop and tablet battery packs deliver watts which means your premium laptop will take a long time to charge and may not deliver enough power to keep your machine running at full performance. Battery packs that deliver 60-watts or more are preferred. When evaluating the overall capacity of the battery pack to understand how long it will keep your device running on the road, compare the watt-hour rating of the laptop vs the battery pack. The high price may be due in part to using more expensive internals designed to support Qualcomm Quick Charge 3.0, but other Quick Charge units we tested cost less. Regardless, performance was respectable but unremarkable, consistently charging our test phone in 130 minutes. With a “normal” (non-Quick Charge) phone, this unit’s charging time was merely on par with other chargers. Larger than the RAVPower but still acceptably trim, the Maxboost also feels as if it was carefully designed and built using long-lasting materials. There’s even a grippy pattern molded into the plastic around the edge of the unit’s “head” that makes it easier to yank out of your car’s DC socket.
The only real difference comes in terms of the shape of each charger. The Vogel was a kind of futuristic gear stick looking device, with all the ports neatly laid in a vertical line. This model chooses to pair them, so it is a little shorter but also a little wider. They are both very good chargers, packed with useful features. If you need a 4 port device, you probably won’t go wrong with either, so just pick the model that you like the looks of better. There are a range of eye catching features with this product, but naturally enough the one that is going to grab the attention first and foremost is the fact that it is packing no less than 4 ports. Look over the specs a little closer though and you’ll see that this device is pushing out 9.6 amps total, or 2.4 amps per port for a total max output of 50 watts. That is a crazy power level, and this is a product that can tackle charging just about any electrical item that it comes up against. So as you see, the lower port is a 2.4 amp standard port – that level of amps by itself is impressive enough. But right above it – and built in red so you can’t miss it – the Qualcomm 3.0 quick charge port.
The spectrum shows high frequency noise at the switching frequencies. This counterfeit charger has so much noise in the output that I had to double the scale on the left to get it to fit. The spectrum is much higher everywhere, indicating noise at all frequencies. Surprisingly, it has only a moderate amount of ripple; the manufacturer seems to have done at least one thing right. The large degree of ripple is visible in the waveform and the very large spikes in the spectrum . The thickness of the yellow waveform shows the large amount of high-frequency noise, which is also visible in the very high peaks in the spectrum .
