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?

Mods, please move this, I'm sorry

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.

Review of MPow 4.2A dual usb car charger w/lots of pics!!!

This is a review of MPow 4.2A dual usb port car charger. http://www.amazon.com/Mpow®-4-2Amps-Charger-Android-Devices/dp/B00HLHHBHA/
Car charger is probably one of the most common smartphone accessories. We all like to take trips, stream our favorite music stations, keep our eyes on the traffic with Google maps, make some phone calls, and maybe even have wifi hotspot running for other passengers in the car. All this is going to drain your phone battery in no time. That's why we need to keep our phone on a charger while driving. And not just any charger, we need something that's going to source enough current to charge your phone at max speed. Let's take a closer look at what I found.
Both of the MPow car changer units, black and white, arrived in a nicely packaged box with a front display showing the actual charger. Taking it out of the box revealed a very compact dual car charger, about 3.5" in length and almost 1" across usb port side. When I say compact, I mean it was a size of a regular single port charger, while they were actually able to squeeze two in there. Another good point about compact size is that it won't take too much room in cigarette outlet and won't interfere with anything next to it. Once plugged into the outlet, it has a nice soft blue light to indicate the power is on and also to guide the connection in the dark. I do have to note that usb connection itself is a bit on a tight side which is actually good to hold the cable without falling out. But at the same time pulling on the cable will actually remove the charger itself unless you hold it down with your hand.
The most important test is if it can actually deliver 2 amps per port. A lot of the chargers claim they do, but it only works when one port is plugged in. In this case, I was able to confirm charging my Note 2 at max speed (the same reading I get from my original 2A Samsung wall charger), and I was able to do that while also charging Nexus 7 (HD, 2013 edition) which charges at 1.5A. Although I don't have two Note 2 to verify full 4.2A dual charging capacity, I have a feeling that won't be a problem.
Overall, I found this dual usb car charger to have great performance, solid build, and delivering it's advertised charging capacity without a problem. Covered by 18-months warranty and currently on Amazon for $6.99 (down from original $9.99, need to use code MPOW01CA at checkout) - this is one fantastic value!
Here are the pictures.

Good review. My car has a USB port built into the head unit, and it really isn't meant for charging. My Galaxy S III would just barely stream music via Slacker and hold the same battery percentage. If yoou're getting the same kind of charging capabilities out of this as you do with you wall charger, that's mighty impressive. I think I'll have to put this on my list of general accessories to get.

Hello Vectron, I just checked the amazon link, it's $7.99 now.

Thanks for pointing it out. I noticed they (MPow) constantly run specials on their products (car chargers, speakers, batteries) which gets noted in special offers section with a coupon code.

Perfect review. Might pick this on up.

Do you know the lowest price of a car charger? I found many car chargers which range from $7.99 to $14.99.

Vinsic 5-Ports 40W charger REVIEW

Hey guys so I received this along with a 4.8amp dual port USB car charger. I must say the quality is exceptional. The fact that this is a new up and coming company is really motivating. Hopefully all their products follow suit. Their powerbank 20000mah is made from an aluminum frame so it's a quality build as well. Anyways on to the review!
Upon opening the box from Amazon I noticed the two items came packaged really nice. I could compare it to anker in the packaging but Vinsic is just more visually appealing. I'm a big fan of the blue.

It comes with a power adapter cable for the charger. I'm not used to having to connect one to the charger. I've enjoy having the plug built in to the charger itself. I'm just spoiled by travel chargers I guess. It's not a huge difference but for the power it delivers it is most definitely worth the change.
The 5 port charger itself has a nice weight to it. It is polished smooth white. It has a very nice feel to it. Doesn't feel cheap at all. Very sturdy feel to it. On the bottom it has 4 rubber feet. There's 1 in each corner for it to have maximum grip on whatever surface you place it on.
The size isn't that much bigger than a Galaxy S2. Here they are side by side. My trusty S2 on the left of course.
Here's some battery stats. Looks like it's charging at the maximum rate for the S2. I doubt it's this exact amount but it is charging beyond its capabilities. The battery is not heating up at all and I've ran it from completely dead to 75 so far. I'll post some ampere pictures from my Nexus 5 as soon as I can run it down a bit more. My Nexus 5 is at 75 right now.
Overall for the money and quality of the product i'd highly recommend it to anyone. This is my favorite at home charger now. The anker sits in my gym bag waiting to travel lol ?.
Hope you guys enjoyed the review. Any questions feel free to ask. These models were sent to me by vinsic but the review was unbiased.

this is the 3rd brand of mutiport chargers ive purchased and all have been junk. this on in particular gave me unpredictability issues from day one. 1 port would charge my ph and others wouldn't. 1 would charge my tablet and others wouldn't. bought it for the kids to use to charge multiple devices at once in one location and has not been able to do as it is promised, after about 2 weeks it stopped working completely. I tested the main power cord with my multimeter that wasn't the prob. i tested each output port and got no reading on any of them. i was tempted to crack the case and test further but then I wouldn't be able to return it.
If any one has any advice on a good multiport charger id love to hear about it..

I've had no issues so far but I'll keep an eye out. Maybe it was just a defective unit. Have you tried anker? They are extremely reliable as well but they have some defective units too. Check them out on amazon.

Guessing this is the item you reviewed? $18 and Prime shipping, not bad at all.

Does this come with a power cord?

Yesterday I received from amazon my new car charger. I chosed vinsic one because of the quality of they' re products, feedback,reviews here in xda forum and the first impact with the design, looking very different from low quality chinese products.Let me start telling that this charger is great,maybe a little heavy but it gives you a sensation of quality compared to my old one made of plastic,and the stainless steel material used gives you the feel of premium quality and a great look with the engraved logo and specs.Even the box is not cheap as other products cause you find a manual,a warranty card and thanksgiving card for chosing they re brand.The charger has 2 usb ports 2.4a each,that can charge both a nexus 5 and 4 without any problem (they could both draw from 1.2 to 1.7a on nexus 5)and spot a little green led that light up when connected to car.If you look on vinsic site they say they use an high quality chip inside to ensure a great reliability and protection that shut off power in case of overvoltage overheating and short circuit ,even the shape is made for security,you can use it to smash windshield in case of emergeny,but I wish i will never need this feature .The only little problem I found is that maybe in a car with the cigar lighter in vertical position the charger will not stay strong inside the plug, but in myne I had no problem.So what to say,this brand looks promising. Next item when I get my pay will be the 20000 mah vinsic battery in this review and I will tell you about it:
http://forum.xda-developers.com/google-nexus-5/accessories/review-t3067486

it can even be smashed into (or thrown really hard?) into your windshield to get yourself to safety if something happens?

Yes sure is heavy ,I think about 100gr, it s heavier then a nexus 4 for sure, or maybe is cause weight is concentrated in a small object. It s not a declared function,but on they re site you can see the picture I posted with a smashed glass

This is an amazing car charger to have. The Slick chrome top and black bottom gives it a unique design that not many car chargers these days have. I just plug it in the hole and it turns on for you to plug your Phone's Usb Cord Cable in. The Green light that displays when it is plugged in, is really nice and innovative. Since it is a Dual Port, it both has a 2.4a port for each to have both an even charge for your devices. So far, I have plugged in my Motorola G Phone Cord in it, and it works great. I also have plugged in one for my tablet, and that charges pretty good as well. The time it takes to charge my devices are at a good rate as well. I would say about 2-4 hours if leaving it in the place where the cigarette hole is at.
Now since I couldn't show my phone using the port, I had to use one of my tablets. As you can see from looking at it, the light turns solid green when it is plugged in. How cool is that. I will recommend this product to my family & friends.

I bought one as well, but it as not working. Actually, green led is shining but is is not charging my Note 3. I bought it on Aliexpress. I contacted the seller and he send me another one free of charge. But, the same thing. Green led is shining but it is not charging my phone. Anybody experienced same problem?

I tried again today. With very same cable it charges some Alcatel android phone, but not Note3

The Samsung micro AB cable uses 5.3 v. Not the 5V USB standard. I have a galaxy tab and can't get anything but the official charger for these services and official cable to charge at high amp. You can plug a microB USB into one side of the port and it will charge at .5 amps or so.

AllMaybe 6-Port 12A Desktop Charging Station - Review & Unboxing

Unboxing
This accessory comes with an standard packaging (not eco-friendly unfortunately) and some accessories: 1x Protective Pouch (nice quality), 1x Power Plug (mine is an European Version), 1x User Manual, 1x User Satisfaction Card, 1x Warranty Card and the Charger (of course).
As regards the Charging Station, it is made of Plastic, entirely covered with a rubber-coating, a bit fingerprint unfriendly but it guarantees an excellent grip on the Desk.
On the front, there is an useful Power LED (Blue) that could be pretty useful if you need to find the charger in a dark room or just to know if it has been plugged properly to the power socket. Just like another Charging Station i have reviewed, its color doesn’t seem to change, so it is just a standard Power LED.
Being a Charging Station, it couldn’t have had few USB Ports. There are 6 USB ports available that support Standard 5V output (2.4A max each, but also more, check my next paragraphs to know more), i don't know what the "IM" word means though. (some other technology name made by AllMaybe, maybe)
As regards the size, it isn't super compact, a bit thick compared to others, nothing serious to complain about though.
Efficiency
As always, all my tests are made using high-quality cables (with 20AWG or 22AWG power lines) in order to get the best results. AllMaybe doesn't provide any USB Cable, neither they produce them as far as i know, so i had to go with other brands cables.
On idle, the voltage is just fine: 5.17V. Increasing the current to 1A, it decreases to 5.09V.
Let's start with the real stress test, with 2A of Load the voltage decreases to 5.03V, and with more than 3A of Load (over-specs, do not do this frequently or for long-period usage otherwise you risk to fry the USB Port) it decreases to 5.00V. Great Results!
Something i noticed is a slight buzzing noise coming from the charger on idle, it isn't annoying, but if you place your ear on the charger it is noticeable.
Conclusions
Well, this is the first charger i review from AllMaybe, a brand that was completely unknown to me, available officially on Amazon.com only (excluding other chinese e-shops). What to say, there are lots of Desktop Charger available on the Market currently, some of them with Qualcomm Quick Charge support, others with a different number of USB ports, etc. so can this one be considered too? My reply is: so and so.
I am not saying that this isn't a good charger, it is powerful (see my risky stress test i made) and solid, but it lacks something that, i think, everyone would have expected.
Nowadays Type-C ports and Quick Charge devices are becoming the new standards so the release of a standard 5V charger may be a bit risky. If you are looking for a powerful standard USB charger with lots of USB Ports, i can definitely recommend it, if you need QC Support or anything else, this isn't for you.
Pros:
- Lots of USB Ports
- Powerful
- Rocking Stable Voltage Regulation
- Power LED
Cons:
- No Quick Charge
- No Type-C Ports
- No USB Cables included
- Slightly noisy on Idle

Hi Alberto,
Thanks for your unbiased and honest review. We really appreciate your help and your advice on our product. Yes, we totally agree that a standard charger can not best meet people's need nowadays, so we are developing two QC3.0 chargers at present. They are expected to be available in April. Please keep tuned.
It's true that the charger is not amazing for its size or appearance. It has no advantages in these, but I hope you will love it more and more since you will find it quite durable and long-lasting. Performance is quite good too.
Meanwhile, please allow me to specify some concerns in your review. IM means "Intelligent Management" the same technology as Power IQ of Anker or Aipower of Aukey. Your guess is right.
We have an official website www.allmaybe.com.
This charger is officially available on both Amazon.com and Amazon.ca. Also, it can be found on ebay and aliexpress. We have our official stores on these platforms at present.
Thanks again for your time and help.
Regards,
Allmaybe
