I’m trying to make sure my family has emergency supplies on hand, so I ordered three types of emergency crank/solar radios to try out.This “WR5” model, sold by SNGKMSYG, is my favorite. I like the quick and easy analog tuning, and the use of indicator lights (tuning, charging, battery level) instead of on-screen icons. The buttons for the lights are intuitively placed and they don’t come on with an accidental bump. The speaker's sound is at least as good as the others. The reception is pretty crisp even with the antenna down.The 10K mAh battery will run the radio for 75 hours, according to the manual, but it can also be used to charge a cell phone. The manual recommends charging the battery every three months when not in use.So those are all the reasons I like the WR5 radio best. It seems to me like some thought went into it, and I appreciate a good design. Below I’ve listed some other information that may be helpful to you. I’ve also included photos of the user manual and box, since other reviewers have provided photos of the radio itself.MEASUREMENTS:-- The storage box is 8” wide, and 4.25” high and deep (the end is square).--My kitchen scale says the radio by itself is 546 g, with the charging cord adding another 25 g. The battery makes it heavier than the little emergency radios, but I like having the option of topping up my phone with it, so the battery is worth the extra weight to me.NOTES ON FEATURES:Flashlight– The flashlight has three settings: (1) narrow long-distance beam, a single light in the center; (2) wide-area beam of white ring lights; (3) all lights combined. Most other emergency radios just had one center light.SOS– One long press on the SOS button brings a very loud siren and flashing white SOS light.Warning light– pressing the SOS button a second time turns off the siren, and starts a sequence of flashing red, purple, and blue bright ring lights. The other radios didn’t have this feature.Top light– Similar radios have a top light that automatically comes on when the solar panel is lifted, but this radio has a separate on/off switch for the top light. This means that the light can be kept off while the solar panel is angled to catch the sun’s rays. There are four rows of light dots in the top light panel, rather than the normal three, another nice touch.Solar panel– I turned the radio’s back to the sunshine (to protect the display from heat), and lifted the panel to be perpendicular to the sun’s rays. The charging light came on, so it worked.Crank– This does not protrude much from the back, so use a fingernail or knife edge to pop the crank out of storage position. The handle is small and easy to use; I found the round knob more comfortable to hold than the oblong knobs on other radios. The charging light comes on immediately when the handle is turned. The radio is largish but rests comfortably in the hand when cranking.Removable/attachable handle – The strap handle uses velcro tabs, so it can be opened and attached to a backpack or stake. A couple of radios had this.Compass and thermometer – I didn’t think I would care about these, but actually they are sort of a fun addition. And they seem to be right.
