My review of Eken m013f

[willPanda]

Sorry, the battery has been built-in the tablet. We couldn't change. Eken company isn't like other well-known brand, like apple or Samsung. What they displays on their site are what they sell in the market. Eken F series tablets have the same CPU and similar hardware with flytouch series tablets. But flytouch has better battery. That's also the reason why Eken sold the cheaper tablets. If you want the tablets with 3600 mAh battery, we can order them for you from Eken. But the quantity requires above 50 or 100 with higher price.

pandawill Sorru, but feel the difference between cheaper device and failure device.
Sell the cheap devices but do not sell bad devices.
M013f costs 129 USD and Flytouch costs 165 usd.
165-129=36 usd
For this extra 36 usd in Flytouch you got:
- GPS navigation
- Better battery
- 8 gb NAND
- 512 RAM
- Better LCD with 150 degrees of view
And after that do you thinking that is Eken m013f is cheap???
EKEN M013F is not cheap!

I agree with RuslanMg. Today I will dispute the paypal transaction.
129 USD is not cheap, also, look at your answer and service policy on your web page:
"Pandawill chooses products to sell based on their excellent designs and proven hardware reliability. In this way, we guarantee the quality of our products. All products bought from Pandawill enjoy 1 year warranty if not specified otherwise.

If you really do the checks, it's impossible that my tablet arrived with the problems that I described in this post. Also today I talked to EKEN Customer Service about my post and they told me tablet it's not from EKEN and that it's a clone. They told me all Eken M013F tablets come with a 3600mah battery because 2500mah battery it's not enough for this Infotmic chip to work. If I sum this with the problems described by RuslanMG and me it's very clear you must refund our money back. It will be great also I you can answer my emails to service pandawillservice@gmail.com because I made all my efforts to get some help from you but an answer like "it's a cheap tablet" I guess it's not what RuslanMG expected and I can assure you it's not what I'm used to.

Question for RuslanMG: Your tablet works with battery or shuts down as mine? If yours last at least some time any idea what might be the problem?

RuslanMG, new Firm is on webpage, apparently a M013F version with gps..........Please can answer me about how your tablet behaves?? On the other side I was wondering if you can tell me how yo open your tablet to avoid if I open it brake something.
It's important to notice that according to EKEN Support M013F comes with x220 CPU, GPS and 3600mah battery and they told me according to them that the one sold by Pandawill that has x210 and 2500mah battery it's not EKEN.

[willPanda]

I can understand your feeling. I told your opinions to our purchasing staff. We cannot get the tablet you said, coming with x220 CPU, GPS and 3600 mah. If it is OK, please show us some pictures of the tablets you mentioned after you get it, not the pictures or information just from a site.

On the other hand, we didn't say Eken m013F had 3600mah on our product page at all. Did our staff replied you that? If that, please tell me who it is.

[RuslanMG]

leovitis As I understand so the GPS, 4 Gb Nand and 512 mb RAM are the additional options. Eken m013f on Pandawill have simple variant with Infotmic x210 (X220 is coming with GPS) and minimal hardware options (256 memory, 2 gb nand).

Overall hardware is good but I don't understand why they have installed not suitable battery. Current battery WinWin 2500 mAh (BH31) is produced for RC-toys but not for tablets!
Please take a look on battery pack:

DO NOT DISASSEMBLE BATTERY!!!
It have two lithium-polymer banks and IC controller.
IC controller is prevent battery from damaged caused by the overcharging, deep discharging, circuit closing and other bad things.
How it do this? IC controller works with battery power level. Usually tablets and other devices uses this levels:
~4200 mV - Max Level, battery is fully charged, IC controller break circuit and stop charging, Android show 100% charged
~3200 mV - battery is low, Android show battery low alert screen (about 5% battery) and ask user to pluging charger
~2900 mV - Min Level, If Android do not shutdown system then IC controller break circuit to prevent deep discharging, device is turned off.
The power less than 2500 mV is get battery slowly died. Also power more than 4500 is going battery for explosion.
And temperature over the 70 C is bad for battery.

I have tested two my batteries WW 2500 mAh. And I found that IC controller breaks circuit not at 2900 mV, it breaks circuit at about 3400-3500 mV. This is why tablet turns off at 40% battery level without any alert screen. Battery controller simply turn off power.
Why it do this? I have answer! Some manufacturers can set Min and Max power levels is about 3400-4300. It is for longer battery lifetime (more cycles of charging-discharging). This is good for RC toys but not for tablets! Android tablets working with diapason 2900-4200 mV.

Just buy li-pol battery designed for tablet (not for RC toy ). For example in Flytouch used battery PTI 3800 mAh (code 455689). It works about 7 hours! Stange but WinWin battery also have code 455689. Maybe Eken simply confused with battery shipment?

So, my friends Pandawill and leovitis. Did you understand what I mean with battery???

My Eken m013F tablet works with battery about 3 hour (Flytouch tablet with 3800 battery works about 7 hours).
I will make video for you about how to disassemble M013F. I can do it at 06 November.

Tell me please is it far from Pandawill office?

Shiyan Industry Zone Baoan Shenzhen Shenzhen Guangdong China
Phone 86-755-81335826
If you like your customers then take a bus and please go to PTI Battery and get TWO batteries (one for me and one for leovitis) that are usually used in Flytouch (7.4v 3800 or 3600 mAh, for TABLETS). ))))

Mine can't do that. Only works with AC Plugged in. I will be very happy if at least mine worked 3hs. Battery shows at 100% on Android but as soon as I remove the AC Plug the tablet shuts down. It seems to me mine is working like yours when you received it. Unstable, shutting down. Only works with AC plug.

I have 3 ideas about possible problems

1) Faulty Motherboard because AC power and Battery power comes from different sources in the MB.
2) Faulty Battery
3) Battery it's not enough to move the tablet power consumption and shuts down. AC Power has a 9v output and 1,5A while Battery has 7,4v and 2.500mah..2,5A.....

Is it possible to put AC Power through battery connector to motherboard (wiring cables) to check If the problem is only the battery? I want to make sure the battery it's my only problem and not a faulty motherboard. My situation it's much worst than RuslanMG. RuslanMG works 3 hours, mine only works with AC Adapter plugged.

Pandawill, we have an open dispute on Paypal. Let's try to find a solution to this problem as soon as posible.

As I said it before, I dont care about X220 cpu and gps (only difference with x210 is GPS) but I want a working tablet. Mine is faulty. About 3.600mah, Pandawill customer support told me to check manufacturer page (Eken) and Eken M013F page states 3.600mah battery. We can move closer to a solution on our dispute If you send me a working battery and maybe a working motherboard in case the problem it's not only the battery but when I say a working battery I don't want another 2500mah battery, I want the 3600mah that suits this tablet.
