Review: Trustfire TR003P4 Charger

Paws Off !!!!

Available from here and here 

TrustFire Multi-Function Li-Ion Battery Charger - TR003P4 (110-240V/DC12V)

Its been a while since there has been a new charger from Trustfire , I wont dare mention who may have lit a fire under them. 

 

So seeing the new charger a while ago , I decided to drop some coin on it rather than driving my car [ fair exchange ] , since I already had enough chargers I needed to be able to justify buying another , and after giving the charger some what of a shake down , I have to say its a fairly good charger for the money . Lets get on some details first : 

With a 18650 @ 3.16v  the 4 bays returned - 0.63A - 0.65A - 0.67A - 0.67A

18650 @ 3.52v the 4 bays returned - 0.55A - 0.53A - 0.53A - 0.56A 

18650 @ 3.67v the charger varied from 200-360mA

18650 @ 3.93v the charger varied from 140-160mA

18650 @ 3.97v the charger varied from 120 - 150mA

18650 @ 4.07v the charger varied from 83-99mA and with another cell 97-112mA

18650 @ 4.12v the charger varied from 70-82mA

18650 @ 4.19v the charger varied from 25-75mA 

Now with 2 batteries in place - I tested several combinations of bays ...

The charge rate went from 0.67 or so Amp to 0.51A there was little variation after that when you added more cells ..

 

Termination seems to be around the 4.19v range to 4.21v [ so far ] 

The charger behaves much like the WF-139 or WF-188 , in the sense that it seems to check battery state about once every second [ what my MM can detect ] , it does appear to sort of terminate charging , and what I mean by that , it does not actually turn off the charging channel but rather goes into a monitoring / stand by state [ around 2 to 3mA ] and if another cell is charging it may check battery state kicking current up to 20 to 40mA as it does so , again very much dependent on my MM [ How accurate it is ] . 

Now what I like about this charger = It will start charging from 4.19v . And so far has terminated from 4.19v to 4.21v , it has a decent starting charge rate [ current ] but looks to ease off in a almost linear fashion rather than at certain voltage levels , this makes the charger some what slow as the charge rate has eased of quite a bit before the battery even gets to 4 volts , but the upside of this is that the charger would be very gentle on the 18650 and quite possibly help in putting in as much charge as one possibly could [ Hmmm gives me an idea for an experiment ] , anyhow . 

So by now your probably wondering what batteries the charger will handle ...

18700 fit with room to spare , should be no issues here ..

16340 , I put in the shortest ones I had , and again there should be no issues here ..

I have to say the charger looks to be well made , the lid looks to be well made , as well as being attached firmly .

The sliding tabs in each bay move with no binding , and also appear to be well made [ Ive had a tab bend and break before ] , should be no problems in this regard ..

Each charge channel does appear to be independent , I saw no evidence to show otherwise .

And this is the first charger with a open voltage of 0 volts , yeah even with a battery in one channel the others read 0 volts   ...

Voltage input range is 110 to 240v and there is a 12v DC input [ 2A ] , if you have a 12v sig adapter .

 

I like this charger , and I will use it as much as possible to see if it does something strange , so far so good , and from the testing so far , I would recommend this charger [ based on my sample ] . 

 Always remember , the easiest thing in the world to do , is to expel hot air from your lungs and through some vocal chords ..
The resulting sound may , or may not be worth listening too ….

Good review....convinced me to hit the "Add to cart' button.

BTW what voltage did the cat terminate at?

The cat was not terminated :  If anything she was standing over the TR003 as I was paying too much attention to it ...

Thanks Old! Im amazed that this actually seems to be a decent versatile charger... and at a true bargain price. Unless I missed it, have you tried swapping cells at various resting voltages from station to station to see if you could confuse it? Im sure you know the drill. I see that you tried this with 2 batteries to some degree but 4 would be much better. It would be interesting to see if a cell that reached charge completion in one bay continues charging when swapped into another. Or if after swapping 1 cell into another bay, adjacent cells suddenly terminate early or late. One method that gets most cheap chargers to hiccup is when one bay completes charging and an empty cell is swapped in its place while the other batteries remain charging in the other stations. Sometimes the remaining batteries suddenly terminate when they are not yet topped off.

I didnt realize that you had an assistant. Very cool looking cat displaying the proper illumination test pattern markings.

 

Nope , not with this one ...

I tried a few things to trip it and I failed to do so ..

Thanks for this review Old. I have to put one of these on my wishlist.

I see, you have got a nice feline assistant.

Thanks for the review!

 

Do you know or own the xtar wp2 at the same price? 

Any idea which ones most suitable for xtar 18700 2600? i would suppose the xtar but could be wrong Smile

Yes , her name is Tikki , she is almost 1 year old now , and for some reason , Im her favorite ..

Might have to do something with my brother dumping her on my chest [ I was lying down at the time ] and she simply refused to hang out with anyone else for the first 3 or 4 months of her life , then I had to go to school , and since then she has become more independent [ Thank goodness ] 

She is a very good cat !  but for the first 6 months , she would no leave me alone , and that was a royal pain .

Hows the new charger working out? Have you found any flaws yet?

 

Im using it as much as possible , just charged a cell overnight with it , pulled it of the charger some 30 minutes ago [ 7.20AM ATM ] and it was 4.19v , and it was a unprotected cell [ 18650 ] , Im rather pleased with it , so far its terminating within the 4.19v to 4.21v range , which is good .

This one came from KD , and if mem serves Manafont advertised the carger about 3 days after I bought mine from KD ... So at the time of purchase , it was KD or Ebay ...

The Manafont page shows it as also handling 10440's.  Although one would fit it I can't imagine how it could be safe for a 10440.   Its charge rate for a semi-depleted sub-3.6v cell is far to high a rate for a 10440.

Is this a so called intelligent charger? Ric from cnquality says the DRY is brighter with unprotected cells (sanyo 2600) but i was going to buy protected 2600 xtar cells. As and inexperienced user, wihtout time to constantly monitor the batteries i think unprotected cells would be unsafe. Unless (what ric told me) the charger is intelligent...

I have charged unprotected cells - and they come out the same as protected ones , 4.19v to 4.21v

my xtar 2600's are now 8 hours charging and still it doesn't say fully charged, i'm getting afraid that i have a bad charger :s, can't measure batteries as i don't have a meter. Will ask a neighbour if i see him.

Take it easy, it is a very slow charger and your batteries might end up above 4.2 volt.

Seems about right my Ultrafire grey 2500mAh take 6Hrs to charge on my Ultrafire wf139.

I'll have some more patience then just thought 2600mah/500mah = around 5 hours, but i was told good batteries also charge slower... So i will see Smile

The WF139 is fast compared to TR003P4

If the charger does use a CC/CV algorithm a good estimate is to add 50% to the calculated value. The CV phase slows things down.

The TR003P4 does not exactly charge with 500 mA, 150 to 200 mA would be more correct. If the batteries are empty it will take more than 12 hours to charge.

First battery is charged after 9 hours, put it in my KD C8 and wOWOWOWOwowowooot!

The light i owned before seems to put out 75 lumen max if i compare to the low of this light, just sick ... and then i still have a NW dry coming up Shocked

Does anyone with this charger feel the battery in slot #1 is warmer than slot #2 and so on?  Not that the heat is really noticeable just slightly warmer down the line.  I am currently recharging Samsung ICR18650-22E recovered from an old laptop cell.  So who knows the battery state, but I just think it's a little weird that the slot #1 battery is heated a bit and the slot #4 battery is cool as a cucumber.  (All reading the same charged voltage btw)

Soshine and Xtar can do 1A , but even they tapper off and the chargers are really not that much faster ..

If the cell is depleted enough , its going to take a while , 

Using my TR001 , I charged up my brothers 18650's , and it took about 10 Hours [ he really drained them ]
