But the LA DA’s warning also applies to USB cables that have been left behind in public places. Microcontrollers and electronic parts have become so small these days that criminals can hide mini-computers and malware inside a USB cable itself. Something as benign as a USB cable can hide malware nowadays. USB connections were designed to work as both data and power transfer mediums, with no strict barrier between the two. Not only is it packing incredible power, it’s also extremely well designed, it looks great and it is surprisingly small. This is our second entry from Ainope, which has already impressed us with that very attractive model above. This product is also good looking, with a zinc alloy finish that is scratch resistant. This model doesn’t sit quite as flush in the accessory port as the previous one however, and the reason for that is the built in LED screen that is mounted in the faceplate.
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.

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.

As of this writing, Aukey’s Omnia PA-B2 is the smallest USB-C laptop charger on the market. This diminutive wall wart measures just 1.77 x 1.77 x 1.18 inches, which makes it even smaller than RAVPower’s tiny Pioneer RP-PC112, which is just 1.9 x 1.9 x 1.2 inches itself. The Omnia PA-B2 is also a full 0.45oz lighter than its competitor. If you’re using a 16-inch MacBook Pro or another USB-C laptop that requires more than 65 watts of juice, the Aukey Omnia PA-B5 is your best bet. Though it is conservatively rated for 65 watts, in our tests, the 3.65oz Aukey Omnia PA-B4 managed a maximum sustained rate of 72.6 watts (19.2V / 3.78A). After 20 minutes of that maximum the temperature hit a steamy 139 degrees Fahrenheit, but the charger was a much cooler 120 degrees, the second coolest of all chargers we tested, when run at 64 degrees.

Separately from that, there’s USB-C, which is a physical connection standard that devices can use. In almost every case, your PC is the host, and your smartphone, tablet, or camera is the device. Power always flows from the host to the device, although data can flow in both directions, such as when you copy files back and forth between your computer and your phone. The descriptions below apply to all versions of USB currently in-use, including USB 3.0, 3.1, 3.2, and their various substandards (1×2, 2×2, etc).

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 Samsung oblong charger came in best, using just 19 mW; this was so low compared to the other chargers that I measured it again a different way to make sure I hadn’t made an error. On the other extreme, the fake iPhone charger used 375 mW. The Apple iPhone charger performed surprisingly badly at 195 mW. If plugged in for a year, this would cost you about 21 cents in electricity, so it’s probably not worth worrying about. In the following table, I use the official charger Star Rating System .I also measured efficiency of the chargers under load. One of the benefits of switching power supplies over simpler linear supplies is they are much more efficient at converting the input power to output. The chargers I measured all did pretty well, with 63% to 80% efficiency.

Place the batteries against one side of the box and put the ‘battery holder’ not directly against the batteries, but about 1 cm off them. This means you will need to solder it with the grey tip away from the solar panels. This way the electricity can flow from the solar panels to the batteries, but not the other direction. Now you solder 1 wire to both 5V pins/wires an 1 wire to both ground pins/wires. Now you take one switch from one of your solar garden lanterns and solder it to one of the wires.
