Review on ARCCR100R SNG: American Crank-Powered Flashlight Smartphone with Enhanced SEO by Tim Loya

Very light construction so don't expect it to last very long. I can see it will help you survive an emergency, but other than that I would doubt it's permanent. You can feel the very thin plastic case flexing in your hand as you scroll. If they added $0.50 more plastic it would be very durable. load 1 watt. generally slows down and the charge rate drops to 0.5W when the voltage drops below 5 volts. Spinning very fast does not increase charging speed or cause power surges. So if you spin at a constant speed for 5-10 minutes, you will hopefully get enough charge to make a call. I suggest getting a longer cable and having someone roll on for you on the call. Calculate how much time you reduced by 1/4 of the time you can do. So 10 minutes start is 2.5 minutes talk time. It won't even charge a drained cellphone enough to even turn it on. With a 1W charge, you have to crank it up for almost an hour to get enough juice in a modern dead smartphone to turn it on. I highly recommend pairing this with a small "USB battery pack" and every time you just sit there, light up this thing to charge the small USB battery. For the price, it's better than nothing, but if you want something, this is a REAL emergency charger. , you need to spend a lot more, and I suggest buying a large foldable solar panel first. (Unless the panel is almost 5-10 times the size of your phone, it's useless.) The ETON Boost Turbine is better and has a built-in battery, but you'll only be charging around 2-3W with its crank. The reality is, you don't want to use a crank to charge your phone.
