Review on πŸ“» Emergency Hand Crank Radio with LED Flashlight, AM/FM NOAA Portable Weather Radio | 2000mAh Power Bank Phone Charger | USB & Solar Power | Camping, Emergency Preparedness | by RunningSnail by Janet Rivera

Revainrating 5 out of 5

Decent block with good features at a good price

I am very happy with this little device. It may not be perfect, but it's only twenty dollars, so five stars. Revain says it has a 1000mAh power bank, but the included instructions say it's 1200mAh. I would estimate it between 1000 and 1100 mAh. Overall impression: The flashlight is not very bright, but good enough for most normal tasks in the dark. There are no brightness and flash modes, it just turns on or off. The radio works quite well - the volume is increased very quickly with the volume control - at 10% of the way it is already quite loud. I haven't fully tried it. The tuning is fairly sensitive (tuning changes quickly as the knob is turned slowly), but not too sensitive to tune into stations if you're paying attention. The sound quality is thin and bright, but what's the difference - this isn't meant for listening to music. There is no headphone jack. The antenna works great for VHF and broadband, it's quite short but helps with reception. The charging handle rotates normally, but it needs some work. A minute of running makes my arms tired and a little sore. Scrolling for five minutes is a lot of work! Part of the problem is that it's difficult to find a good place to hold the device when it's cranking without squeezing it more than it should. Also, the grip you hold on the handle is a bit small. But for a minute everything is fine. You can charge your device via USB using the included cable, which is definitely an easy option. You can also charge external devices with the internal battery. I don't know the output current it provides, but it does charge my iPhone 5. More details below. I ran a couple of tests FYI: with the device fully drained, I cranked 130 revs (about 1 minute) and then turned on the flashlight. It lit up normally for the first 20 minutes, then it started dimming and dimming. But he kept beaming. And shiny. And shiny. Finally, after more than 9 hours of constant dim light, I simultaneously turned on the radio and very soon everything went off. Who knows how much more he could shine. Keep in mind that almost all of those 9 hours were very low light, but in total darkness it's still very helpful not to trip over things when your feet are pointing at them, and to do normal chores when you point at them, what you do. Good for emergencies. Then, when the block was fully discharged again, I cranked 130 revolutions and then turned on the radio. At a moderate volume, it played for 12 minutes before stalling. How about charging phones? I have a fairly old iPhone 5. With a fully discharged flashlight I did 1300 turns (10 minutes) - no small thing! I then connected my phone to charge from the device. It added about 2% to my phone's battery before it stopped charging. I then made a call (all with no cellular data, Wi-Fi, or location services, and on low battery mode). My call took 5-6 minutes to use up that 2%. Keep in mind that my phone's battery isn't what it used to be, so mileage may vary. I also checked the capacity by fully charging the device via USB. I don't know how long it took, but definitely less than 6 hours. I then charged my iPhone 5 (again using battery saver settings). This increased my phone's battery level by 75% before it stopped charging. It took just over an hour. I checked one more thing: When the device was completely empty, I plugged in my phone and got started. It charged my phone during startup. I didn't specifically test the solar charging, but I put it in the sun and it seemed to charge. In fact, even with bright interior lighting, it shows the charging process.

Pros
  • Absolutely amazing!
Cons
  • Not bad, but...
