ShaunM: Is as advertised. Keep in mind that a crank can only provide so much power. That said, its flashlight is surprisingly bright and it is conveniently small enough to fit unobtrusively in the compartment between the front seats in our 2012 Prius,

Katrina Trotter: Comes in handy if you want to walk around the block and listen to your favorite radio station or at night time walk with a flashlight

Craig Arno: I bought this unit over several others for; USB-C connector, Solar, Hand Crank, cell phone charger, Radio, and Flashlight. This unit has all these features with a few caveats, which I'll explain in the "Cons:" section.

The battery is one 3.7V 2000mA cell and is user replaceable, a valued feature.

The Flashlight draws about ~20mA of power. It's not super bright, but bright enough and will run a -long- time off one charge.

The Radio draws about ~40mA of power and will also run a long time off one charge.

A cell phone drawing 5W of power will drain the battery quickly. But if you need it… hope you have other sources of power or lots of sunshine and lots of time.

Pro:

Solar — When I want to charge, I put this on the sill of a south facing window. The red charging light comes on solid to show it's charging.

USB-C — The world is switching to this connector for power and data. This reduces the amount of different cables and adapters I have to drag with me to run things electronic. (See caveat in Con section). The RED charging light blinks when charging from USB-C which requires a 5V only, non-PD charger, 1A or better.

ejhejh: With the prevalence of low cost and products containing Lithium-Ion batteries with little or no safety protections and lying about capacity I always test anything I receive with an Li-Ion battery for basic safety features. For those who don't care about the details, the TLDR for this product is it's honest, good, and safe and a impressive for the price. For the geeks, keep reading.

I tested voltages and in numerous ways via the USB ports and on the Li-Ion cell directly. Here are the results.

Li-Ion shrink-wrap label states:
Li-4.44WH
17500 1200mAh 3.7V
Manufacturer not listed

USB tests: (KJ USB tester)

Voltage/Amperage
Micro-USB Input: 5V ~500-600mA
USB Output: 5V ~1.0-1.1A

Input capacity test via Micro-USB charge port: 5.875Wh avg over 2 tests (5.88/5.87)
Equivalent @ 5.0V (USB): 1175mAh
Equivalent @ 3.7V (Li-Ion cell): 1589mAh

Output capacity test via USB port: 3.01Wh avg over 3 tests (2.97/2.95/3.11)
Equivalent @ 5.0V (USB): 602mAh
Equivalent @ 3.7V (Li-Ion cell): 814mAh

No battery is 100% efficient in charging or discharging, and the above is not unexpected.

Stu: Smaller than I expected but big on quality. Radio and flashlight are excellent, the crank works as it should but the solar charving is a real bonus. I like it that I can charge my phone off the little solar panel.
