The Lumsing Fast Charging 2.1A Output Portable 10,400mAh Power Bank Battery Charger Powered Backup Pack is a very nice external battery that has a decent amount of power. This is a great charger for your phone or other electronic device. I have dedicated this one to my phone and during a 5 day period it kept my phone powered and charged without any problems.

I was looking for an external battery pack for 2 power hungry devices and this seemed to fit the bill. Ipad external battery holds charge for weeks and I have thoroughly tested this product. I deliberately short-circuited this product, not once but FOUR times and it still works. This product can take anything thrown at it and I would highly recommend this to anyone looking for an external battery pack. Does very well what it says it will.
This is awesome! Last Christmas I bought a different brand external batteries charger for my husband and two more of yet another brand for my kids. As the year went on, I was wanting one for my self but never bit the bullet to buy one, I would just borrow one of theirs in a pinch; but they always complained. When I saw this deal I decided to go for it and I am so happy I did and I'm even happier that I waited because this one is far superior to any of the other 3 and It was priced at less than half the price of the other three. The benefits of this one over the other 3 we own are:
This one charges up much quicker than the other three. This one is about half the size of the other three. This one has a window that shows what number percentage of charge it has left; the other three don't. This one came with a 2 in 1 charger/sync cable and a two ended USB cable to use with any USB plug for charging it. and most importantly this one charges my devices much much faster than any of the other 3.
Yesterday my iPhone 4s was down to 20% so I plugged it in and it was fully charged in less than an hour and only used 20% of the stored portabel batteries, so I still had 80% left. This is by far the BEST external charger of the four in my house and it's all mine! I highly recommend this for anyone on the go, I take it with me everywhere I go, it's so small I just toss it in my purse and don't even notice the weight of it. It works with my iPhone 4s, my Kindle, my Kindle Fire and my iPad. I love it and I could not be happier with my order.
Great Portable external battery, with nice quality feel, and multiple ports with different charge currents.
The 2a output charges devices nice & quickly.
Comes with charging cables & adaptors for many devices. Also includes a handy travel pouch to protect it when being carried in a bag.
I'd recommend this for the price, but it's not the most efficient in my experience, only managing to charge my Nexus 5's 2,300 mAh battery 3-3.5 times on one full charge of the battery (65-70% efficiency).
This means it'll recharge around 7,000 mAh of battery, which is still good, but a fair bit below the 11,000 mAh advertised & can be equalled by smaller portable batteries, though perhaps not at this price.
Overall I'm very pleased with this charger & would recommend it if you want a good quality, low-cost portable battery charger.
Portable power banks External battery pack have been around for a while and have gained a lot of traction as the number of portable tablets and smartphones has increased. Many companies have focused on add-on battery cases and pen-sized power banks that give your device a quick charge to replenish the battery.
What's in the box?
- A Manual Sheet
- Soft & Durable Lumsing-Branded Carrying Case
- Micro USB Cable
- Lumsing 10400 mAh (LUM-008-01)
Where does the Lumsing 10400 mAh (LUM-008-01) portable battery exceed?
I don't know where to start with this beauty, so let's start with build design and quality. Superb! End of story. Seriously, this power bank is super light, yet it backs a punch with the amount of juice (Geek term for "energy") it packs inside. I tested it with my Nokia Lumia 810 and Samsung Galaxy S4. Results displayed remarkably accurate. This power bank in-cases a 10,400 mAh rechargeable battery while my Lumia 810 in-cases a 1800 mAh rechargeable battery and my Galaxy S4 in-cases a 2600 mAh rechargeable battery.
I'm very happy with the results especially since my Galaxy S4 eats through the battery like a mad man! The power bank is a true pleasure to have when I'm longboarding on short/medium trips.
As far as ports are concerned it features two USB 2.0 Ports (in the front) and a Micro USB Port (on the left side). Also, there's a button and four LEDs (in the front) that display the power banks rechargeable battery level.
The rest of the body is very slick and smooth which is a con that I will get to later in my review. I adore this design that Lumsing power banks has went with and this being my very first product from them speaks loud and clear! Recommending products to my audience, customers, and so on is what I do and this very one from them is high on list.
This Lumsing power bank batteries comes nicely boxed and is very compact but still manages to provide 3000mAh. In terms of size it is a little bit bigger than a lipstick and beautifully crafted – it measures 3.7” long and is square in section, albeit, with nice rounded corners and each side measures 0.86” with the whole device weighing just over 2.5ozs. In the box you get the power bank with a neat Micro USB lead which doubles for charging the device as well as connecting to a lot of smartphones, plus instructions, warranty/support details. If you want to charge an Apple device you'll need the appropriate lead.
The exterior finish is mainly coloured aluminium that looks very chic with white end panels. The top end panel sports a full size USB port with a standard 5V 1A output plus a Micro USB socket for charging. On the side is an on/off switch and a 3 LED charge/charging indicator - when the battery senses no load it switches off automatically. There is also a small LED torch facility built into the front panel which will certainly help you locate your keys etc. The device features electronic charging/short circuit protection etc. plus uses a Samsung power cell sio it should be safe and carries FCC, CE and RoHs approval marks. The unit takes around 2.5 hours to charge from flat .
In use the power bank is easy to use and despite its modest size it will recharge an average smartphone nearly twice but rather than a charge from flat, if your battery is running low, it will prolong your usage of the device itself considerably. In the case of a tablet it will extend the usage time or charge it a bit but obviously not to full capacity. I tested it with an iPhone, Nokia Lumia 630 Smartphone, Samsung Galaxy Tab 3 (7”) and it worked very well with all of them.
Because of its compact size, chic look and reasonable output this is a mini sized external battery power bank that you are likely to have with you when you need it most, plus, it has enough power to be genuinely useful - I like it a lot. Recommended.
In descending order the outputs are 1.3A, 2.1, 1A, 1A and 0.5A.
Blue
lights indicate roughly the amount of power remaining External battery charger for samsung galaxy, and blink
synchronously when charging. To charge it, you will need a micro USB.
It takes roughly a day to charge on a 0.5A charger, quicker with higher
output chargers.
It has one smallish recessed button to turn it on.
WARNING: it does NOT come with a wall charger.
Personal perspective:
I bought this because it had 5 outputs, and in this day and age, you need
to charge a lot of devices, especially when traveling. I think the
printing on the input and the outputs needs to be larger. I have great
vision and I struggle to read it, hence why I put the descending order
of the outputs.
The lack of a separate charger is not a problem
for me, I actually prefer it; one less charger to lug. I have another
power pack with two outputs. That one has a wall charger, so I just
charge this power pack from the 2.1A output of that one, and charge that
one at the same time. It is some much faster. On a recent trip, all
my devices (tablet, 5 phones, iPod, portable speaker - I rotated them)
and power packs were fully charged by morning.
The button is
slightly smallish, make sure it comes on when you press it. It's also
recessed, that way it's not likely to get turned on accidentally.
Plug at least one device mini sized external battery in first! If you turn it on, it will turn off within 10 seconds if nothing is attached.
The one thing that I think would make this perfect is if it had a higher
capacity. That being said, 11,000 is quite good, plus my other one has
12,000. I prefer the long haul, non-stop flights between Europe and the
EU. I'm not running out of power.
At Cable Chick, we use an icon system to indicate how many device charges External battery power you're likely to get out of a Power Bank before it needs to be recharged. Our figures are based on a formula which assumes an average device capacity of 1500mAh, a device power level of no less than 20%, and an 80% Power Bank efficiency rating. Many Power Banks boast efficiency ratings up to and over 90%, but we find that real-world usage in Australian climates typically ends up with an 80% efficiency rate.
We also like to err on the side of caution to give you a conservative estimate rather than make outrageous claims. Generally, the bigger the Power Bank and the smaller the device you're charging, the more goes you get. Other factors can also improve or limit the discharge potential of a Power Bank, so look after them and they'll work better for longer.
Our Formula:
Power Bank Rating (mAh) × Efficiency × Device Depletion ÷ Device Capacity (mAh)
Look for our handy icons to immediately see the charging potential of our power banks for use with smartphones, or use this formula yourself to calculate the number of charges any device could get. All you need to know is the mAh rating of its battery!
