Review on 🔌 Tripp Lite 4-Port USB 2.0 Hi-Speed Hub (Model U225-004-R) by Derrick Shaw

This isn't the company's fault but I bought this product specifically to simultaneously charge my portable devices. As it turns out, USB hubs typically only charge up to 500mA (0.5A). This makes charging my devices very slow. For example, my iPad requires 2.1A and my Samsung 4S phone requires 1A for fast charging. So my advice is, if you need a portable charger and you want to charge your portable devices as fast as possible, buy a dedicated charger, not a USB hub. Most USB hubs charge very slowly as their specific purpose is to transfer data rather than charge devices quickly. The keywords for this are "Wall Charger". Each port must be at least 5 watts for a 1 amp charge (for a phone) and 10 watts for a 2 amp charge (for a tablet). So a 4-port fast charger with two 1 amp ports combined with two 2 amp ports would be a 30W charger. Remember, keep a minimum of 5 watts per port. (5 volts x 1 amp = 5 watts) Hope this helps. Anyway, it's skinny. Much luck.
