Car Chargers

Hey Everyone,
Thought I would start a car charger thread.
I picked up one of these at Walmart the other day:
http://store.griffintechnology.com/smartphone/powerjolt-dual-universal-micro
And it works quite wonderfully. It's tiny, and even with bluetooth/GPS/Navigation running, it was slowly charging the battery. And it charges it quite quick if you don't have nav running.
It can be a bit annoying to pull out once stuck in, although you probably don't need to do that very often.

I have the single port version of the one you have cracking charger and sits flush worth the extra few pounds over the cheap ones and delivers plenty of juice

If you have amazon prime you can get it for less than $10 in two days here:
http://www.amazon.com/gp/product/B0042B9U8Q/ref=olp_product_details?ie=UTF8&me=&seller=
I got it the other day but haven't driven far enough yet to need to use it
Glad to hear though that it charges even while using GPS.

what is the exact output of each USB of this Griffen car charger ?
i have a JABRA charger (comes with JABRA Cruiser) and it doesnt seem to charge my GN while GPS navigation is on (even though its saying charging on the battery icon)
it used to work perfectly on my HTC Desire HD (with GPS+Bluetooth+WIFI ON )
any recommendation on how to fix this please ? like a reference output current that is enough to charge the GN while navigating ?
thanks.

The Griffen claims 1A per USB port, and I believe it.
Online reviews say some users with other phones need to mod the Griffen to charge their phone, otherwise it only supplies 100mA. Some crack open/mod the Griffen to short two terminals to get the full charging ability, and/or use a 'charging cable' which shorts the terminals within the cable.
As a reminder, the Griffen seems to charge the Note full blast, but perhaps something similar is needed for the Jabra. I suggest installing 'Currentwidget' to see what sort of charge you are getting.

SGP has one as well, it will lit up BLUE!

OR you can just get a no brand one on eBay for around $3.

Thank you for the reply.
I have battery monitor widget installed & it shows charging via usb when i connect it to jabra charger, but the weird thing is that the galaxy note starts mtp mode once i connect it!
Could it be the cable? Or shall i just take the griffin charger to solve this?
By the way,griffin charger works out of the box out do i have to solder modify it?
Cheers

I just bought this dual port 2.1A + 1A charger on eBay for £2.49 inclusive and delivered the following day....
http://www.ebay.co.uk/itm/2-1A-Dual...neChargers&hash=item19ca66b4df#ht_2865wt_1163
At first it seemed the phone was only drawing a "USB" level of current, so I was all set to rip it apart and solder the centre pins to force AC charging, but when I double checked with a dry run and a temporary short the phone switched to AC charging. Now it seems to be continuing to draw "AC" levels, so maybe I had a poor contact initially and a few (un)plugging operations have made the contacts more reliable. I'll try it out later today with satnav running and see if it keeps up with the pace and report back.
EDIT : Charge level draining like water out of a sieve with this thing whilst running satnav, and the phone said it was "AC" charging too. Switching ports didn't help.

i'm using the official car charger from my old nexus, the only charger i found can charge my phone with 3g and nav on because of the 2A output. other cheap usb chargers i tried with so called 2A output just don't work

Monoprice 2800mAh portable battery box

I just got a portable battery box (2800mAh) for $14 from monoprice. (LINK)
Nicely built, relatively small, and about to test whether it will give me 1.5 full charges as mAh would suggest (2800mAh / 1800mAh on HOX = around 1.5 charges).
Box itself doesn't come with any charger, but is able to be charged by any charger with Micro or Mini USB connector (yep, it has 2 inputs).
Output is a male MicroUSB connector that fits HOX nicely (duh!).
Output: DC5.0V 800mAh

I'd imagine if you want to use the phone while charging from it, you can connect them with a female-male MicroUSB connector.
The charger has a button that shows the charge level of the box with 25% increments (4 lights).
Has another light for "FULL".
As soon as I connected the box to HOX, phone immediately showed that it's being charged, as if from the regular charger. Not sure what the current is, but it may come across as slow charge (USB port charge) as opposed to AC charger.
So far I tested the charge over 10 minute deep sleep period, and I got this:
With the box, in average HOX charged for 2% every 10 minutes.
That would suggest that it would take this box 8.3 hours to charge HOX fully, which isn't bad at all, considering you're free to use it while it's charging.
Over next day or so I'll try to completely discharge the HOX and charge it overnight from the box. I'll see just how much this box can spit out.
---------------------------------
EDIT/REPORT:
I discharged my phone to 5% yesterday, disabled wifi and BT, and connected it to batt pack to charge overnight.
It turns out that this batt back is crap.
Overnight, when phone was in deep sleep with wifi/BT off, a full battle pack charged my HOX only by 55% (I charged the batt pack before using it). Even considering some small drainage during charge, I'd say this pack actually acts if it had just over 1000mAh or so, nothing close to 2800.
Oh well, gonna return it and keep looking.

shouldn't this be in the accessories forum?

Hate the ones that plug right into the phone like that. Pretty much makes the phone a huge pain to use. I would rather spend the extra money and pick something like this up

That's a good option too, although I actually like that monoprice's sticks right into the phone, so you don't have to carry a cable with u.
Also, it seems smaller and cheaper.

I know of certain defense organisations that allow the fixed connectors but not those with detachable cables. Disallowing the cables reduces the risk of the cables being used for data transfer.

huh?

It's a security standpoint from Defence services (IE: Australian Army, etc) who wish to minimise security leaks. A data cable can be used to link up other devices, not just the charger.

Okay, and I guess if I were flying in outer space, my suit was venting air, and the only thing that would save me is connecting a batt pack to a phone - in that situation a cable could freeze solid to a connector on the batt pack, making batt pack unusable, and thus killing me.

WRONG!
That's when Iron Man comes flying to the rescue thus saving your life and getting an autograph that you could sell on eBay for some money and covering your costs of the HTC One X.

OK well, turns out that this batt back is crap.

Portable Chargers Comparison

For some of you coming from phones with removable batteries, you may have some anxiety about running out of battery life and not being able to swap a spare in. I was the same way a year ago, but I didn’t let that fear keep me from buying a newer phone without a removable battery. So I decided to just grab a few portable chargers to use and I’m glad I did.
Below is a comparison of the portable chargers I have. To try and compare them as fair as possible, the process was simple. Reboot the phone, fire up the stopwatch, set to 15 minutes, shut off the screen, plug in the charger, and leave it alone. The readings were taken from Battery Monitor Widget which was set to update the history every 60 seconds. I used a charging cable from my HTC EVO 4G LTE. I didn’t have my N5 charging cable with me and we know sometimes the cable can play a big role. So take that in to consideration if you think my numbers are off.
The portable chargers from left to right.
1.New Trent iCarrier 12000mAh Portable Dual USB Port - $39.95 (Amazon)
*The one I have is an older model which doesn’t included the “Recharge by USB” option. Mine can only be recharged via AC Wall Adapter. The new model has both options but doesn’t included the wall chargers.
2. Anker® Astro 5600mAh Portable Power Bank - $29.99 (Amazon)
3. Anker Astro Mini 3000mAh Ultra-Compact Portable Charger Lipstick-Sized - $19.99 (Amazon)

Review for Each:
New Trent:
I originally bought this to be used with my Nexus 7 (2012) since it was REALLY picky about what could charge it. You can tell this is a lot bulkier than the other two and isn’t something you’ll throw in your pocket. I keep this in my backpack and only use it when I don’t plan on moving around. Or if there are two people/devices that need to be charged. The plastic housing feels a little cheap, but I understand the idea was to keep the weight down on an already ‘heavier’ portable charger. It has held up well.
I’ve used this thing 3-4 times on my phones without it dying which is nice. This one re-charges using a AC Wall Charger (No longer included) or via USB (5v 2A…no charger included). NOTE: I have the older model which does not have the “Charge via USB” option. Only the AC wall charger option which it did come with. I can’t imagine how long it would take to charge via USB. It already takes a long time using the AC Wall Adapter.
Anker Astro:
This has been my Go-To portable charger for over a year. And it still charges my phone at least twice. When it comes to size vs. capability it is the clear winner. It also includes a LED Flashlight built in. There is a 4 light meter that tells you the status of the battery when charging a device or when being charged itself. Or you can just hit the button to see how full it is.
It can easily fit in your pocket or purse. I have a few very short micro-usb cables laying around so I’ll bring that with me too so I don’t have a 3ft cable in my pocket.
Anker Astro Mini:
I just bought this on sale and was surprised at it’s weight when it arrived. It has a metal casing so that probably adds to the weight. The fit/finish is very nice looking. When holding this in one hand and the Anker Astro in the other, you don’t feel much of a difference. Yes the Mini is round/smaller, but it isn’t a huge difference for me. The mini fits in your pocket nice.
If you are looking for something very portable, a little cheaper than the other options, and a charger that will charge you up once (maybe 1.5 times), then this is a good option. But if you may think you’ll need the portable charger for more than 1 charge while out, go with the Anker Astro (5600 mAh).

I have the Anker astro, but it takes AGES to charge my n5, almost as if it was being detected as a pc usb port rather than a charger.. any ideas? Stock rooted...

What cable are you using with it?
Get the battery monitor widget app and see what it says when plugged in.

Nice quick review.
Strange that New Trent 2A output is less powerful then regular usb..
And the average charging mA for Astro mini seems bit lower than it should be. Both Astros have the same output rating, arent they?

Moto 360 Mobile Charging Solution - USB OTG

I have been playing around with my Moto 360 for the past few days and the one issue I have is the battery life. Here is my solution which has given me extended use throughout the day... USB OTG on my Samsung Note 2
I tested this today and was pleasantly surprised with the results so I wanted to share this with the community. I assume this should work with most devices that have USB OTG capability but results may vary. Please post your results if you are able to charge your Moto 360 from your phone using USB OTG.
Now, on to the details & photos.....
Items required:
Moto 360
Moto 360 Charging Dock
Note 2 (or other USB OTG device)
USB OTG Cable
Standard USB to Micro USB Cable
How-To:
Connect Moto 360 Charging Dock to phone using the USB cables and set your Moto 360 in the Dock
***NOTE*** This will drain the battery on your phone. I usually carry a couple charged phone batteries as backup; they can be found online for a reasonable price.

Nice I hadn't thought of that!
I'm tempted to get one of these qi-enabled battery packs:

Does it not defeat the purpose? If you have a dead phone, whats a 360 gonna do? I know you are relying on a spare battery, but most modern phones have an internal ONE. YMMV.

My phone wasn't dead after but I didn't give the watch a full charge either, just a nice boost while I was out. I know many of the modern phones have internal batteries and this may not apply if your phone's power is limited.
I specifically didn't buy a phone with an internal battery. I would rather be able to pick up a couple spare batteries online for $25 than have a useless phone after the battery wears out.
But, like I said in the first post... results may vary

the Qi stone+ looks great but its freaking $80!!!! and only 4,000 mah?? forget that
heres a better solution... get a Qi charging puck for $15 in amazon.. glue it to the back of a 10,000 battery pack that are now like $20... use a $1 6inch USB cable and done... wireless charging OTG for half the price of that stone.

I almost took my Moto 360 back. I couldn't get the battery to last a full day. I solved it and now can go from 5:30am to 10pm and it's still over 40% battery left.
Read this post to learn how I did it.

very cool idea. 60 is a bit high for it tho.

Yeah.. Great thing.. Just saw today morning on android central that Samsung was selling usb OTG cables to do the same with the gear watch
Lucky for me too.. I have the same note 2... I also got a xiaomi 10000mah power bank always lying around, which is sold here for throw away price. (Only 999rs.. 15$)..And even if you don't have spare batteries... a Samsung charger is ubiquitous and omnipresent in India...

Good Wireless Charger?

Has anyone found a good, reliable wireless charger for their G7 yet? (My cheap $15 charging stand isn't cutting it and I'm about to whip it against the wall).

I've been using this one by Anker, charging it overnight. Takes about 2 hours to fully charge from about 30% to 100%
No issues with it yet but only have had it about 2 weeks now.

Thanks! I have about 4 older Samsung charging pucks. What's strange is that two work fine, but the other two don't charge my G7 at all. (I'm sure it has something to do with the USB cable and/or plug that I'm using).

Bear in mind that you have to use the supplied cable, along with your o.e. charger for the Anker stand. The port on the back of the stand is a micro usb, not a usb-c.

I've been using one like this one for years no issues and good brand..
I have the older model but I see this one with same specs

G7 will say fast charging on a 10W wireless charger but LG says the phone supports 15W for true fast charging. Belkin and a handful of others make true 15W fast wireless chargers.
Watch out for off brands as many will say 15w but are actually 10w.
Im using a mophie here and it says fast wireless charging at 10w.

Good call on this charger. I picked it up on your recommendation after seeing the price before I even owned this phone and I can confirm it works great. Anker makes solid products so the price makes it even better. Thanks!

Another vote for the Anker Charger
I've been using the Anker model A2523 wireless charger with no problems. It doesn't charge super fast, but I use it for overnight charging, so that's not a problem. While charging, the battery never goes above 30 degrees centigrade, which is 2 to 4 degrees cooler that when I was using the original LG plug in charger that came with the phone! The Anker uses a Micro USB port for power, so I also got a USB-C to Micro USB adapter, so that if I need to recharge quickly, I can just unplug the LG charging cable from the adapter which is plugged into the back of the Anker charger and plug it into the phone. I think that's the best solution until more USB-C wireless chargers are produced.

No, it just states it's charging wirelessly. It's not too fast but perfect for overnight without roasting the phone or battery.

just got the UMIDIGI Q1 , and it says fast wireless charging.
Have some others scattered around the house that is 5w, like choetech t513

I have quite a few Anker products, so when I was looking for a bedside wireless charger, I was almost sure I would end up with them. However, after researching on Amazon for about an hour, I ended up buying the Yootech Wireless Charger (the goofy company name made me think that it might be a cheap rebrand, but it's been a rock solid device). I can say for the LG G7 that this is an amazing charger (although it supports a wide range if you or someone else might want to use it with a different device; especially an older one) that comes with an impressive AC adapter (it doesn't get warm while in use, something that sometimes happens with more compact adapters). It does use MicroUSB instead of USB-C and maxes out at 10W instead of 15W, however it tops up my phone from 20 - 30% to 100% in less than two hours so it's a keeper for me and allows me to save my included charger specifically for travel.

I got the BlitzWolf BW-FWC4 from Amazon for €15. Fast wireless charging thanks to QI-EPP compatibility. Works flawlessly through my Voia case. Charges almost as fast as wired. I'm using the original wall charger to power it.

got the nillkin 15w qi powerflash. Fast charging works and cooler than UMIDIGI Q1 thanks to buil in fan.

Hey, what are the charging speeds on the Nillkin? Does it charge as fast as the UMIDIGI ? Their description does not mention fast charging for LG so was wondering.
