2-in-1 Hand Cranked Dynamo Survival 2-Mode Flashlight + Phone Charger

Pros: Good plastic, bright LEDs, 120 mAh lithium accumulator with very simple charging circuit (voltage¤t limiter) inside; has simple output voltage limiter (one zener diode); phone adapters are compatible with adapters from same devices (each adapter have 4mm male jack for connecting to charger device); has good silicon grease on the mechanism inside; good lays in hand.

Cons: Not very useful for phone charging (it's hard to crank for 10-15 minutes for enough charge) - it good just only for one emergency call; manual inside on Chinese.

Other: Good flashlight, but only for for long travel - battery-powered flashlight will be more useful in case when you can easily get fresh batteries, and phone charger also isn't very useful for regular charging.

Pros: The build quality is good, the crank is a little stiff and it feels as if you might just snap the handle but it seems to be made of a fairly solid plastic.
The light stays on for much longer than other crank torches I've owned, which is a plus, and it's bright enough to read a book with (some were a fairly dull LED light.)
So far, it hasn't blown up any phones that I've attached to it to test the charging capability.

Cons: It didn't have an attachment jack for Sony Ericsson phones.

Other: Great. Have come back to buy another, that's how good these torches are.

Pros: This device proves itself as being very useful in different life situations. While camping it may be used to light outside. It can be used to charge telephone in extreme situations so it is very handy to have such device on you as you might need it.

Cons: This might not work for a long time because the handle does not look like one made from the very best plastic.. Not sure that it is going to break soon but this is possible.

Other: I would definitely recommend this product for everyone to use. With the god price and good quality of it.

Pros: 1. Phone charges, it works fine
2. Shines brightly, perfect for lighting the tent
3. All moving parts are lubricated with a white grease
4. Soldering is well.
5. Inside is a li-ion rechargeable battery, unlike the cheaper ones, which is use CR2032

Cons: 1. Fairly noisy charging process, like for all dynamos
2. On my dynamo there is no marking of the switch
3. It is difficult to turn the switch to light diodes 2. Either they are disabled or burn all 3 of them
4. There is no adapter for Samsung

Other: Good product for good price. I recommend it for all survivals, turists and other active lifestyle people

Pros: - Is actually reliable — I've been using one periodically for more than a year.
- Three LEDs cover all my brightness needs (city flat, cellars, forest camping).

Cons: - Have to use the crank often as the charge doesn't last long. A friend of mine has a flashlight of comparable power which lasts much longer (2 to 4 times) from the same amount of muscle power spent.
- The handle feels like it will break any moment (it doesn't though).
- Both hands are needed to operate it. You can't hold and crank it with one hand.

Other: Good utility flashlight, I'm extremely happy with the purchase!

Pros: =excellent build quality =very bright light =provides more light than some 10 LED flashlights =battery has high capacity as it lasts a long time after decent cranking =

Cons: none

Other: this is one of the best quality flashlights(hand cranked ones), that you can get from anywhere, at this price, buy this one, you won't be disappointed.
