An impressive looking product, came in an excellent pack and put to charge.There are four small green LED lights set in a column configuration on the right side of the two ports. These start twinkling in sequence when the power bank is being charged and when there is about 50% (am presuming) charged then only the last two lights twinkle and the first two remain constant. This is how we come to know how much charge it is carrying. Once completely charged all the four led lights light up and remain constant.The two ports are for charging your devices. The power bank came with a 1/2 metre or so charging chord with usb/micro usb on either side. For charging the power bank the micro usb side is inserted into a provided slot on the longer side and the other end has to go into a plug charger (this piece is not provided).Have not really calculated the time that it is taking for a zero to full charge or for a half charge to full charge as it is kept for charging in the night. Has been utilized for charging just one device at a time till now.No heating detected, no device issues other than the fact that it is quite a heavy product. Ideal for people who carry a bag fairly regularly, or if being used whilst connected to a device where both are stable (i.e. not ideal when you are walking & talking for e.g.). Overall I am quite satisfied.

I ordered a TP Link 10400 mAH power bank and flipkart has shipped Digiflip 2600 mAH power bank. Amazing service guys. This is like 1.8k and the one you gave was 350 rs. Do you guys even check the order before you ship? Terrible shopping experience. Never expected this from FLIPKART! Kudos to your team.

I purchased from Electro4Shoppe seller. This stupid shameless seller sent me a duplicate chinese copy of Sony Power Bank. Look at the guts of these sellers, he didn't even bother to arrange for a TP Link Duplicate. Please ban Electro4Shoppe seller. Everyone please avoid the seller Electro4Shoppe. Product is good though. I am using other one from ws-retail seller.

Bought it for Rs. 1299 last week 10th June. Charging takes 8 hours to charge via 5V 1.5A charger. It charges my Asus Zenfone 5 (2110mAH battery) 3 times full + one spice triple sim phone (1000mAH) once (3 days time) then fully drained. Overall 7300mAH output excluding phones running time while charging. 70% efficiency is not great but comparing to all available power banks (Max 50% efficiency), this one is good n way better. I need to see the reliability in coming days. Do not buy cloned OEM Sony/samsung and craps like lappy master, portronics etc... Reviews of ADATA is mixed and reviews of Lenovo is good as well.
