Won't Charge my ASUS Transformer Prime or my Samsung Galaxy Tablet
340209
In my opinion, Jackery and/or Amazon dropped the ball on this one. I first purchased the Jackery Giant. It worked well with my phones. When it would not charge my ASUS Transformer Prime, I called Amazon customer service. Amazon referred me to Jackery for e-mail support as the Amazon CSR did not have a contact phone number for Jackery to give me. I e-mailed Jackery and received an acknowledgment of my inquiry as follows: "We'll further investigate your case and respond to your message asap. Thank you!" When Jackery failed to follow up,  I contacted Amazon. Amazon agreed to issue a refund once I returned the unit. Since I still needed a battery, I arranged to return the Giant and purchased  the Giant+. Well, the Giant+ will also not charge my ASUS Transformer Prime or my Samsung Galaxy Tablet. It will charge my ASUS Nexus 7 2013. Since the whole purpose of a battery this powerful is to charge tablets, I am very disappointed and feel that Amazon should post a warning that these units will not work with 10" Android tablets-or perhaps tablets with a greater current draw than others. I am not an electrical engineer.
And it's now two weeks since I contacted Jackery with no further response-I guess ASAP means more than two weeks. I will concede that both the Giant and Giant + are well-made attractive units. I am keeping them for now while I search for an alternative but their functionality is limited.

Don't be fooled, this devise would not charge my Galaxy Tab 10.1
All I get is a red X over the battery icon.  Contact Jackery and they said yep, it won't charge it.  They said they had already notified Samsung and made it sound like it was Samsung's fault.

Cable doesn't work. I let my tablet charge for a whole day and it didn't even work. It didn't charge at all.

Some computers won't recognize this and furthermore, some devices won't work when plugged into it.  :-/

Seems to not want to charge properly without multiple disconnects & reconnects.

I purchased this charger and it does not work for my tablet. I left it plugged in all night and it didn't charge it at all. I plug another charger into it, and it turns right on.

This tablet does not charge. It is a known issue with the transformer tablets, yet ASUS and their vendors continue to send them out to suckers like me.

In the end I will win, because they will refund me completely and have to pay for shipping both ways >8]. Talk about a stupid business model. It would be way more profitable to just send out working devices.

It has been 2 weeks and I have not received a response from amazon or tigerdirect regarding the issue.

I have 2 samsung galaxy S4s, and a samsung galaxy tab 2 tablet.  Each device comes with a 2 amp charger.  My galaxy tab 2 doesn't even begin to charge on this outlet, even when it's the only thing plugged in.  Total fail.

I can charge both of my S4's simultaneously on this outlet using the usb ports.  I have a feeling it might be more of a trickle charge going on.  I have no proof, but I bet if I used the normal charger that comes with the phone, it will probably get a full charge faster.  But, I can have both phones plugged into the usb ports and both phones get 100% charge over night.

I gave it 3 starts because while it's usable for our phones, it's a complete failure for my tablet.

I bought this charger because the charger for my Nexus 7 broke. I was hoping to save a few bucks and take the cheap way out. I should have just bought the charger from Asus in the first place. It charges my phone (Samsung S3) just fine but will not charge my tablet while I am using it. I am going to keep it as a travel charger.

Doesn't seem to charge other devices unless it's plugged In..

None of the reviews up here referenced actually charging an Asus TF101 tablet; which the device is sold as, and which I'm using it for. The specs on the website indicate max output as 12V/1.5A, but the charger itself indicates 12V/1.5A or 15V/1.2A (both 18W, of course). The OEM Asus charger (model AD827M) output is listed as 5-15V/ 2-1.2A - so this device should be good-to-go for anybody actually charging an Asus tablet. Mine recognizes it and charges in roughly the same amount of time, and a heckuva lot cheaper than $51.00 for the OEM Asus one. I use tablet/charger for travel extensively (plug it into plane outlets occasionally) so I'll update if it fails. Seems solidly built, plugs fold as in original design, etc. It is slightly bigger than the OEM Asus charger (AD827M/the charger that came with my tablet) in all dimensions, HxWxD.

tried 6 android phones low quality and this didn't charge them at all on power adapter. Lights came on when connected to USB3 super charge asus board. Still couldn't charge while phones were on.

I have had the Asus Eee Transformer TF101 tablet for only 3 months, absolutely loved it while it was working, but recently the screen went dead, it would not start, or display anything. I called tech support over a week ago and they were going to get back to me in 48 hours...still waiting. In checking chat rooms it seems this is a significant problem with a fair degree of commonality. No combination of button pressing or resets would solve the problem.
I spent a fair amount of time getting hold of someone and finally convinced them to issue an RMA. Results are uncertain, but I will update you when known.
Just thought I would share my experience.

I bought it because I found myself out for long periods of time and unable to charge my phone. I'm happy that its able to charge my Galaxy S4 and iPod classic but disappointed that it does not charge my android tablet (ASUS Transformer Prime TF700T). That just make me wonder if the "Samsung Galaxy Tab converter cable" is need it to charge my tablet, if that is the case why not included the converter cable instead of selling it separate for $3.95.

I recently checked New Trent website and I saw a new product, the NT99D, that its even chipper price ($37.77) than IMP120D and with similar charge capacity.

Pros: Big charge capacity, small enough, and 1 USB cable included.

Cons: Heavy, no AC wall charger, does not charge all mobile devices, Samsung Galaxy Tab converter cable sold separate for $3.95

Advice: Check around the web to make sure that your device is compatible with this charger, but better yet go to newtrent.com and buy the NT99D at a price of $37.77 (compare to amazon's $60.26).

I bought two of these,  thinking that they would work. Neither one of them will charge.

I lost the factory charger for my ASUS tablet and ordered two of these 'rapid' chargers.  The only thing they did rapidly was fry my tablet  Upon plugging it in for the very first time, the tablet reset then would not recognize it had a battery, and would not charge the battery.  The power button no longer worked, either.  After months of beating my head on the wall with PWR+ support, I gave up.  They win.  They told me their insurance requires proof that it was *their* charger that caused any damage.

My suggestion to you is to look for factory chargers (you may be surprised how inexpensive they can be) here on Amazon and stay away from PWR+ products.  You have a nice tablet/phone/whatever, don't try to go cheap on a charger!

Doesn't work with my Samsung tablet. And it's defective om my phone seems like it's loose coz everytime I move my phone it the charging stops. I'm using the 2 chords each for my tablet & phone. So I can say this product sucks.
