Product Information

Most companies advertise how many times their products can recharge popular phones, but if you want to calculate that number for yourself, RAVPower has a useful guide that can give you an estimate. The chemical reaction that occurs inside a lithium-ion cell is complex, but as in any battery, there's a negative and a positive electrode. In lithium batteries, the negative is a lithium-carbon compound, and the positive is cobalt oxide (though many battery makers are moving away from cobalt). These two compounds cause a reaction that is safe when controlled and delivers energy to your devices. When the reaction gets out of control though, you end up with earbuds melting in your ears. What changes a safe reaction to an uncontrolled reaction can be any number of things: excess heat, physical damage during use, physical damage during manufacture, or using the wrong charger.

Often on my trips to the US, I carry multiple chargers as well as power strips as I don’t have multiple converters with me for the devices. I usually use the converter just on the power strip and charge all my devices on it. Now with a wall charger like this, I just need to carry this one unit for all my devices. Yes, I do travel with a range of devices that will need all these ports. With this one, I just need three USB-C cables to juice up the Apple Watch, iPhone, and iPad at the same time as the USB-A powers the MacBook.

If you are charging a small smartphone and that's all, a simple power bank will suffice. If you plan on charging a laptop occasionally as well, or many devices at once, you'll want something with more power and more features. Need to keep tabs on your usage?
