COB Rechargeable Keychain Light - Testing Battery - Disassemble - From Aliexpress

[@crazycrab8578]

got 6 of these, some with red light, after testing them, disassembled a few, took out the small batt, soldered 2 wires on, cut holes on the side, put back together, connected a 18650 batt box , heat glued it to side, put 18650 in, works great, as I live in a Tramper van alot, the red light is on all night, connected 2 more to a Adjustable LM2596S DC-DC Buck Converter, set to just over 3v, which is connected to a 12v batt, 2 of these light up me Tramper van, for me , they work, they are just emergency lighting for getting in and out of cars really,

Thank you so much for showing how it is disassembled!! Mine does not work on battery power so I'd like to open it up and see if it can be fixed. I'm amazed how much technology has advanced, that I can buy a keychain light such as this one for only a dollar or two. Back when if we went to a dollar store, we would get a simple dim LED keychain light that runs on disposable battery.

Glad I could help.

Great job, the best part is you dismantling the flashlight. Thank you.

[@AliWall]

Thanks for watching!

1.30 hrs running time for the turbo light mode?

5:42 Las baterías dicen que tienen una capacidad de 500MAH, pero solo en realidad tiene una capacidad de 150 MAH según el USB Tester, no sé porque mienten así, no es necesario, el producto es bueno,

[@oriansanchez1007]

Es muy bueno, sencillo de fácil uso y soluciona el problema en una emergencia.

[@sebastianpostigo4025]

@@oriansanchez1007 Exacto, pienso igual, es muy práctico, he visto a varias personas llevar uno y me han contado como les ha salvado en un corte de luz o cuando tiene que buscar objetos en lugares oscuros

I just got it for less than a buck and its damn good purchase at this price...

[@AliWall]

If you paid cents then it will be ok, but otherwise the battery runs out very quickly.

[@ManOfSteel1]

actually not even expensive chinese products are reliable because few years back I bought a tablet from teclast company(this is a good local brand there) it had Intel processor and it stopped working within 2 months I charged it less than 10-20times imagine how much I might have used it. when I took it to local repair shop they said that IC is soldered on the motherboard and cannot be replaced. I lost my money & time importing and learned a lesson never buy chinese products if you want them to last longer. so now and then If I get such small cheap amusing things I buy them. china is something you cannot depend on.

[@ilyavig]

how long does it charge? mine is already 4 hours charging and it's still red light.

[@AliWall]

This LED light took 1h40min to fully charge, but its battery capacity is only 150mah.

I've Been Using This Light For About 10 Days Now And Based On My Personal Experience I'll Strongly Suggest To All Of You That, Obviously You'll Never Buy This Tiny Keychain Light Before Testing It With Your Highest Attention. Either Way, You’ll Be A Loser Like Me. 😡 Well… There Are 3 Important Reasons Behind My Suggestion And Based On My Own Testing, I'll Never Recommend You To Buy This Beautiful Piece Of Trash Without Your Acknowledgement. 😔 Firstly, The Most Critical Problem I've Found Is That, After 1 Or 2 Minutes Of Using This Light It Will Start Dimming Suddenly And Will Automatically Go Into Dimming Mode (Candlelight Position) Within The Next 3 Minutes, Which Is The Most Annoying Part Of This Light. 😡 Secondly, I've Observed Closely That, Its Charge Lasts Only For 10 To 20 Minutes If I Use It Irregularly. I Mean, If I Need To Search Something In My Room In A Dark Environment, At This Moment I've Turned It On For A Shorter Period Of Time For Searching My Thing And Again I've Turned It Off Within A Minute After Finding My Thing. Like This, The Charge Has Last For 10 To 20 Minutes As I've Experienced. 😡 Thirdly, The Worst Problem I've Faced Is That, For Getting A Better Output, I Thought If I Kept This Light Connected To A Power Bank All The Time (At Charging Mode) As A Direct Source Of Electricity, Maybe I'd Get A Slightly Better Result From My Previous Experience. But Alas, In This Case The Output Result Also Comes Out The Same. 😡 I Mean… After Continuous Use For Below 10 Minutes While It Is Charging At The Power Bank, It Has Again Started To Decrease Its Light Down To The Candlelight Position Within The Next 5 Minutes Of Time, Which Will Make You Extremely Uncomfortable And Unhappy With This Shitty Thing. 😡 So I'm Never Going To Suggest Any Of You To Buy This Cheap Chinese Tech, By Wasting Your Most Valuable Money. 😶 Thank You Very Much. 🚩

[@AliWall]

Yes, that's how it is. But I think this is China knock off. Original brand need to be much more powerful.

[@ericklein5097]

These are $1.87 what did you expect??? Basic math would tell you a small 500mAh battery running a COB light this bright wouldn’t have much run time. I have the equivalent of an 80,000mAh battery running a larger COB light and I get 4 hours of run time if I don’t use a dimming circuit. It’s a 70W 12V LED panel that apparently puts out 7000 lumens but I can’t verify that.

[@ericklein5097]

Your USB tester initially showed a charge rate of 0.33A but it yielded 130mAh (at 5V) over the course of an hour??? How?? Charge input does not equal capacity but at 3.7v that gives a battery capacity of 175mAh Edit: I see it went for another 40 minutes putting only 27 more mAh in. So 212mAh in or likely a 200mAh battery if it was indeed drained 100%

[@FaridShakil]

@@ericklein5097 Well, Whatever Complaints I've Mentioned Earlier About It, You Better Forget Everything. Now You Just Only Tell Me That, Will You Buy A Flashlight, Which Is Suddenly Converted Itself A Candlelight After 1 Or 2 Minutes Of Running? By The Way, Whatever It's Price It Is Really Doesn’t Matter Just Because, There Has Lots Of Places In This Light Where The Manufacturer Can Cut The Production Cost Of It. Yes I Am Accepting That, As A Cheap Tech Maybe It Is Generating Heat After Using For 3 To 5 Minutes Which Is Actually Not A Big Deal For Me. Even Maybe The Battery Ampere Is Low Of This Flashlight So That It Is Not Giving Output As I Expected. Yes I Am Also Accepting It And It Is Not A Major Problem For Me Too. But The Thing Is… If You Can't Able To Solve Any Useful Task At Your Home With A Flashlight At The Darkest Environment, Then I've A Very Straight Question To You That, "What Will You Do With It And Why You'll Buy It"? Anyway, Since At My First Comment I've Already Mentioned About Important Drawbacks Of This Flashlight. So That I Don't Think It'll Be A Good Decision To Participated In Debate With Anyone About It’s Positivity Or Negativity Issue. So Please Pardon Me If I Unintentionally Heart You And It'll Be My Last Answer To You. Thank You Very Much. (Peace) ★SORRY FOR MY BAD ENGLISH★
