Hands-on review of Samsung 9000 mAh Power Bank/External Battery
In this article, I'll be reviewing the high capacity 9000mAh power bank by Samsung. Read this article if you're planning to buy a power bank and are looking for good options.
I own a Motorola Moto G and recently compared it to the Moto E on this website. I also own a Nexus 7 tablet and another smartphone by Samsung. I work for an organisation that makes me travel a lot to different places, so a digital camera is always part of my trips. With so many devices around you, a high capacity power bank is an absolute necessity to have in your bag.
As we all know, there are plenty of choices available in the market these days when it comes to power banks. You can easily get them in various capacities, from a decent 2000mAh power bank that can charge your device once to an ultra high 20,400mAh that can charge your device 10 times. Keeping in mind my usage and requirement, I finalized the 9000mAh power bank by Samsung. A swipe of Rs.3,200 on my credit card and it was delivered to me within 3 days. The official pricing on the box is Rs.3999.
Buy Samsang Powerbank from Amazon
My decision to select this particular power bank was due to three reasons:
1. High capacity (9000mAh)
2. Decently priced.
3. Samsung brand.
The box contains:
1. A white coloured Power Bank with Samsung branding.
2. A Usage guide.
3. A USB to micro USB cable.
4. A USB to a 30-pin proprietary Samsung cable.
That's it! I honestly expected Samsung to include a charger to charge this power bank as well, but they didn't. Samsung knows that every house now days has at least one Samsung device, so its pointless to include another Samsung charger. And they were right, I'm now using my Samsung Galaxy S1 is charger to charge this Power Bank as well.
The device feels pretty light for its capacity, I expected it to be a little bulkier. There are four indicator lights in the front that light up green when discharging and red when being charged. The number of indicator lights indicate the available charge in the power bank. On the top right corner is a Power On/Off switch. This is pretty useful as it switches the device off and reduces power loss. At the bottom we have two ports, a usb port as output and a micro-usb port as input. The input port will charge the power bank itself and the output port will charge other devices.
This device took around 10 hours to charge itself from zero to full. Although there's no indication that tells us that it is fully charged, I removed it from the AC wall socket when it displayed four red indicator lights. On a full charge, I was able to charge all three of my devices one after the other with one green indicator light still available on the power bank. Pretty impressive! Taking power loss into account, this power bank was able to give back 7000mAh as output with around 1000-1500mAh of juice still available. Also, the output this power bank gives out is 1.8A, which means it will charge your smartphone at almost double the speed of your normal 1.0A wall charger.
On my recent trip to Singapore, I was able to carry it in my hand baggage without any security issue. Sometimes the x-ray machines at the airport don't allow batteries as hand baggage, there was no such problem here. Overall, I'm very happy with my purchase and would recommend this product to all of you. Just be cautious of where you buy it from as there are plenty of fake/duplicate versions of this product available online for as low as Rs.1000.
I hope this review was useful, please let me know in the comment section below if you have any questions and I will be happy to answer them. Thanks for reading!
