Which Portable Charger?

Just got back from glastonbury at the weekend with a dead phone and though investing in a portable charger may be a good idea.
Does anyone have any positive experiance with a charger that they would recommmend?
The veho pebble seems quite good (5000mah) but costs around £35, i dont mind paying this but would rather hear some positive reviews first. Sadly all the reviews i can find seem to be written by the manufacturer :S

Any but...
I have found that any will work, but usually you get what you pay for...

ordered a zaggsparq, seems to get good reviews
has a 6000mah capacity and 2 USB ports to charge devices.
Ill leave some feedback after using it a few times

battery charger
Battery chargers that you know has support.

That didn't work for me. I have a very cheap charger (similar to the one that came with my Milestone, you just plug it in and connect the USB-cable to it and your phone) that does *not* work for the phone (it does for my iPod, though).
The "funny" thing is: using it to charge my phone (or at least try) will switch the phone's "charging" light on but no power every reaches it.
Gave me a hard time thinking my phone (or at least the battery) was broken until I found out ...

MHL/HDMI Out Works!!

Just thought that this feature has been ignored by websites and even Samsung. Seeing the specs list, I concluded that HDMI out was not supported by Galaxy Nexus.
Then I stumbled upon Modaco, and in their review they did mention this functionality.
I bought a cheap knock off MHL cable from the market, and viola! It works perfectly. I am just curious as to why this feature was not announced and anyone failed to cover it.
XDA fellows are requested to share their feedback.

I agree with you that most websites have neglected to mention this function but it is pretty standard on new device releases now and in the Galaxy Nexus quick start guide it has a diagram of the phone with an arrow to the charging port the says Multifunction Jack.How is the quality of the picture?

Picture quality is superb.
One disadvantage is that the phone loses PORTRAIT mode while connected. The launcher becomes a landscape which is quite attractive. But full-screen portrait games run at a 90 degree angle.

I'm using a samsung gs2 one, you really get to see how high res the ui really is. The only thing is the density, It would be awesome if there was a "non root" way to put it into tablet mode.
Its even better with a bluetooth mouse connected

i got one of the cheap ones of ebay for mine and the pictures perfect on full HD stuff!
One problem i am having though is that now and then the screen will go black and loose sound for a second, it can happen a few times a minute or not at all for 5 mins or so but it keeps happening. Anyone else experiencing this?
I've not had chance to test on another TV yet to see if its something on there effecting it or if its the fact i got the cheapo MHL and not the Samsung one.

I did not experience it, but I hardly tried it for a few minutes.
The 'cheapo' cable I bought still ended up costing around 30 USD, so its cheap only by comparison. I strongly believe that it should be coming free inside the box since the functionality is there in the handset.
A few years ago those Nokia sets came with the TV out cable in the box. These phones cost almost twice that and yet.... There is a worrying trend to charge for peripherals - we already see wafer thin batteries in phones and then manufacturers rolling out expensive extended batteries. Next thing we know, they will be charging for chargers and headphones too.
Also would it kill Sammy if they'd just used a simple Micro-to-full HDMI cable without this MHL BS. it is a messy set up resulting in an explosion of cables under your telly, and since three sockets are involved, unreliable too.
Moto uses just a simple micro HDMI port in their sets. How hard can that be for Sammy or HTC to implement?

I brought my cheapo one for £6 on eBay, very good picture and sound, had no blackouts yet.

Hi can you share link and photo of the mhl cable that you bought?
Thanks.

Welcome to nexus. Lol. What's wrong with mhl? Micro hdmi port has its limitations too but it does have the advantage of simple mirroring without extra power being needed. Other than that advantage a messy explosion of cables is still needed to do anything serious.

1 vs 3 cables. Its all about practicality - it's irritating for me because in these days of batteries lasting barely one day, the charger is usually in the bedroom for overnight charging.
Although I did find a workaround - MicroUSB cable off the TV's USB port takes care of the charging side of MHL quite nicely . Clever me.
Also, MHL seems to be a mixed blessing for portrait apps. In HDMI mirroring the display at least switches to portrait when there is a full screen portrait game running. No such luck here. My Flick Golf looks like Angry Birds with MHL!

Completely unrelated: If someone could hack this into Android x86 as a feature, I would install it on my netbook in an instant.

I bought some random $12 MHL adaptor on eBay and while it works the reliablity isn't very great. When I plug my GN in sometimes nothing happens, sometimes it works instantly. Sometimes it works perfectly fine sometime it changes between analog looking static and black intermittently. If you're going to buy one I think you should just buy it retail as buying 2 on eBay (Assuming you get a bad one the first time like I seem to have) it will cost you the same as getting it retail.

what is the HDMI out on the gnexus like, is it basically HDMI mirroring, or are you taken into some mode (like the atrix's webtop)
does it fill the screen at 1920x1080 if i wanted to stream netflix for example or a HD video from the android market

Are you experiencing the phone losing battery even though it is charging? e.g. it kills more power than the USB can provide? Has anyone tried the monoprice cable with regards to this? Thanks guys.

Does using an MHL to HDMI adapter use any additional resources (RAM/CPU/GPU/etc)? I'd imagine it does since it mirrors, outputting to two sources at once (screen on the GN and the output jack). I ask this because the reason I bought one, well 90% of the reason anyway, was to use it for PSX and N64 emulators with a PS3 dual shock controller. I know those put a strain on the system in and of themselves, but it seems like they work even less well when using the MHL to HDMI adapter. There is pretty bad lag with some games, but others are okay (Mario Kart 64 was pretty bad, while F-Zero X seemed to be perfect). PSX is the same way, Intelligent Qube works well but Metal Gear Solid is almost unplayable. But when I don't use the adapter and just play it on the phone it's not as bad. The audio is choppy sometimes but game play is still smooth. Not so much the case when using the adapter...
No lag when using SNES emulator, so it's probably just the added resources needed for the more advanced emulators. Still, kind of baffling that its mostly fine without the adapter and not so fine with it.

yeah best I could find before was $26.49 and I just did not want to pay that for a little adapter
last night I Just started going through the 177 page of crap that comes up for "epic touch" looking for goodies. (most crap cases
if you have FF and you keep EBAY as your default "search" option all you have to do is highlight that number right click "search ebay" (it will "search" whatever engine you have "active" in the search box) not sure if its built in or its a addon I have I think its built into FF.
otherwise yes just plug that number into ebay.

not samsung, but i wouldnt believe ebay on it being 100% OEM. monoprice is something i trust, and this mhl adapter works fantastic

For most things I don't care if its OEM as long as it works (I have learned to prefer OEM batteries unless they are good batteries)
Monoprice. are those prices shipped? is that like a deal extreme site?

Not at all like dealextreme, they ship from california.

I would say it is OEM. I picked this one up 120792846359 back in October and it was OEM and works great. Was the lowest I could find at that time.

Does the Samsung cable have a charging port as well?

I don't know I sure hope so.
although with the extended battery it looks like I can play about 84 minutes of video and I was down to 85% battery life so about 5.6 to 1 minutes to percent. so roughly 560 minutes or about 9+ hours per charge.
WOW and that is at full volume and full screen brightness. assuming that depletion rate holds (I just might have to test that one day)

Monoprice is the bomb. I get tons of quality cables, speaker stuff, etc. from them for incredible prices. Did I mention that their stuff is quality too?

I bought the one from Monoprice that locoboi187 linked in post #7. It's working fine. It was $11 shipped.
In addition to the HDMI jack, the adapter also has a jack to plug in your phone charger, and thus power the adapter and also charge your phone. I had made the assumption that connecting the charger was an optional nicety, but it turns out to be required. It has to be plugged in so that the tv will see the connection. That makes it a little cumbersome since you have both the HDMI cable and the charger cable to contend with, but it works.
Question: Is there any way to turn off the phone screen while its outputting video to the tv?

I don't have anything with HDMI so I can not test but have you tried simply pressing power to turn off the screen?
I know in many programs the program keeps running (podcast player)
moboplayer turns off when you hit power time permitting and if I remember I will try some others. Does core player make an android app?
I bet one of them has a "screen off" function.

If you press the power button to turn off the screen, then the HDMI output turns off too.

I picked up the monoprice mhl hdmi adapter, looks solid. I didnt like the fact that the samsung "oem" one on ebay didnt show a picture of it having a seconday micro usb for charging the phone. I also picked up 220855903037 from ebay. I plan to use both together with 160708041305 and my logitech 5.1 surround setup. Going to have a 20" lcd monitor on the corner table. This will achieve a make shift jukebox. I hope it all turns out like im hoping. Ill make a post with the results.

portable charger?

Has anyone discovered a portable charger with a tip/output that would work on a Xoom. Everything that I've seen just charges over USB and obviously that won't work. I don't want to run out of juice while I'm watching a movie on an airplane!

i read on here that supposedly nokia or one of those other manufactures phone tips will charge a xoom. dont quote me on that though.

I'm almost certain that Motorola made one.
Staples (in us and canada) recently put everything on clearance.
You might find one in store...
EDIT: sorry I mixed up portable with travel...

How long's the flight?

I looked at the XP8000 on amazon and as stated it is going for around $198.00. I looked on Best Buy and was going for $99.00 but is out of stock.

You can recharge Xoom using outlets in galleys area (the plane's kitchen), or even in the toillets. Just ask to any flight attendent.
Don't waste your money in spare batteries.

I use the Energizer XP18000 with (free) Xoom tip. Yes - at around $149 it is not cheap, but it also charges phones, laptops and its 18,000mAh battery is great for keeping your Xoom going for a couple of days
Tips are free for life (with $4 shipping) and it comes with a massive assortment of tips in the box. Well worth the investment.

You should also look into the asus mobile keyboards. I know they have a battery, and can charge some devices that there connected to.

Does the Asus keyboard actually work with a Xoom? Would be rather pointless if it doesnt
Sent from my Xoom using xda premium

nope. Asus is no-go. It can charge USB 2.0 devices, but the main connecter is a special Asus one, only for Asus EEE pad devices.
Best chance is to perhaps make your own connector, e.g. with an old Nokia charger (cannot confirm it myself) and one of those normal usb power banks.

I actually orderer this for fun..
No idea if it would work. and its not the highest capacity, put for 6£ in all its worth a try.
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=300648869804
if it can deliver 1.5a without exploding, it would charge the xoom 30-50%
im also gonna try with the Nokia tip as well! seems to fit.
Wish me luck

More facts:
Nokia Tip works with xoom, confirmed here:

Here it is confirmed that the CCTV backup batteries works very good:

I will confirm it for the Xoom when I recieve the battery from China!

I live in a small apartment and my living room is pretty small. I got the idea to connect a 10-15 ft micro usb extension from my tv using this adapter. does anyone know if a length like that will affect charge performance? how about HDMI performance as well?

I believe so. The hdmi is for the video/audio, and the USB is for charging, so you would have to connect to two ports, then you can plug into your micro USB in your phone. Most smart tv's nowadays have usb and allow for charging, so this is convenient as it will be right near the hdmi. I don't think they allow to charge with the tv off though, in case you were wondering like me. (Was planning on using this as my main charger, but not if tv has to be on to charge lol

Have you tried different HDMI cables?

Yup, I've tried 3 different HDMI cables of varying lengths. My only thought is to try a different TV... but that's kind of useless as I wanted to use it on the living room tv which is actually brand new in itself (only 1 month old). All of my other HDMI devices have no problems, but this is totally broken.

Is there much lag using the Slimport adapters?
I measured my wife's GS3 today through MHL by recording a running stopwatch app and the lag was minimal at 0.04s which made me think it would be great for gaming on the big screen. Thing is I found that when I ran an emulator the lag seemed to increase to a point where games were unplayable.
I'm thinking of getting a slimport for my nexus 5 for gaming mainly as I thought the delay would be a lot less than Miracast but I read somewhere that not only does the slimport affect any lag time between the phone and TV but also the TV itself. Just wondering if anyone our there has used the slimport or miracast for gaming with success?

I have not used it extensively (for gaming) but I have used it with a game called Beat Hazard and it works very well. Also works without problems with a game called Waking Mars. I have not played for more than 10 minutes mind you. I use the video output for XBMC (movies), which works splendidly.
