I bought a speaker last month. The quality of that speaker is very good. I really liked it! But there is a limitation to it. The speaker was specially made for laptops, so the electricity need to be provided using an USB port. It was a problem, because I wanted to use the speaker for listening podcasts and watching movies on my smart phone. It was not possible to use laptop speaker without laptop. I did not have any use of that speaker unless the laptop is on. Then I found a solution, which I am writing down in this post.
Solution to Use Laptop Speaker without Laptop
‘What could I use as an alternative for laptop USB port?”, I thought about it and then I got an idea of Power Bank. I connected my speaker to an USB port of a power bank that I had. But it did not work. A power bank usually supports 1 A and 2 A output. I have Lenovo 2.0 – M0520 speaker. The speaker needs the input of 0.5 A. The power bank did not adjust the current according to the requirement of the device.
I bought a new TP Link power bank after few days. It is so far the best power bank that I have seen. I connected TP Link power bank to the Lenovo speaker. I used the 1 A output of it. The speaker worked perfectly! It seems that, the TP Link power bank adjusts its current according to the connected device. Now I can connect my smartphone to the laptop speaker, as the speaker is not depended on the Laptop USB port for power supply. The power bank works perfectly as a power source for the speaker.
Speaker does not consume a lot of electricity. The capacity of TP Link power bank is 10400 mAh. If you charge this power bank once, it could provide electricity to the speaker for hours. I think Power Bank is a good solution for using laptop speaker without laptop. It works perfectly for me!
