Sheri wants a good battery backup that will last a long time and will enable her to recharge via solar. Leo says the problem with solar is that to be portable, it'll take days to charge because it would be so small. That's why Leo recommends crank chargers. They also have emergency radios built in. Campers also have camp stoves that will charge the phone by converting heat to electricity.
Kyle has an Android phone that is very slow to charge. Leo says that there's more wattage through the plug in adapter than the USB adapter. That's because a wall charger has more amps. He can get a higher wattage charger, which will make it faster. The larger the pipe, the faster he can fill it. Plugging into his computer with a USB cable won't go that fast.
Leo says he can get lipstick sized chargers that contain 3350mAh batteries. Anker makes them for $10, and it charges via USB. It would fully charge it one and a half times. He can get larger ones as well that can charge the phone several times.
Greg wants to buy a quick charge charger. Could he damage his phone with a cheap one? Leo says no, but a cheap plug could overheat and catch fire. The quick charge circuitry is developed by Qualcomm, and they handle most of the processors in phones. So if it says Qualcomm on it, it'll be fine. But if it doesn't, then it's probably a cheap knock off. Even then, the wattage won't hurt his phone. Leo recommends Anker chargers.
Dickie D is back from CES in Vegas and there's one gadget he thought was perfect for the tech guy. It's called the Zolt Laptop Charger Plus, and it's the world's smallest and lightest laptop charger that can charge just about any laptop out there. The Zolt has 3 USB ports built-in that allow it to charge multiple gadgets at the same time.
Amy has several chargers and they all charge at different speeds. Can she run a speed test to see how long it takes to charge them? Leo says she can monitor power usage with the P3 P4400 Kill A Watt Electricity Usage Monitor. This plugs into the wall, then she can plug a charger into that. There's also this USB in-line voltage and current meter from ADAFruit.
Tim has a Samsung Galaxy Tab tablet and it won't hold a charge. He tried to use the charger with his phone and it won't take a charge either. Leo says that means the charger connector isn't seating properly. Leo suspects the cable itself is damaged. Leo recommends looking for a microUSB charger and he should get one with a minimum of 10 watts. That will guarantee that his device will charge faster. A new cable could do it as well, if it's detachable.
Mike has several mobile devices and would like just one charger that can handle all of them. Leo says that the Charlie Charger does that. It's a commercial charger that handles up to six phones. Unfortunately, with Charlie Charger the more devices he connects, the more the amperage drops.
Mike needs one that can devote a certain number of amps to each port. Scosche makes a 10 amp charger, giving two amps for each of the 5 ports, which should work great for Mike.
Jane is thinking of getting a "solar powered" phone. Leo says not to get it, it doesn't really work and takes way too long to charge. The solar panel is just too tiny. She could get a solar charger that she can charge her phone with. Leo got his son Henry a Goal Zero Charger. This will charge a battery and then she could use the battery power to charge up the phone.
