We are forced to carry power banks with us, when we travel for any length of time because few smart phones these days, deliver a full day's performance without a recharge. Blame it on heavy apps like YouTube and always-on Internet. So a power bank that offers a 10,000 mAh charge -- equal to three standard phone batteries -- and still packs them into a palm-sized 210 gram frame is good news. The Amani type ASP-AM110 is all this, thanks to using Lithium Polymer rather than Lithium Ion cells.
This is the new trend and while the power-per- area is slightly lower, the solid polymer makes it very light weight and experts say this technology is safer and not explosion-prone like Li-Ion. There are 2 USB ports for charging two devices simultaneously, at 1A and 2A, but the output is the standard microUSB 'A' and if your phone uses Type 'C', you will need an adapter. A small disadvantage, but otherwise excellent value at Rs 1,119 at https://amanimart.com.
