DIY power bank is easy but most people don’t find enough time to make it and just buy it rather than making one themselves. But we have found if you try to make one yourself you can actually get a really decent power bank in just half of the price of a power bank available online.
And also there is the joy of building something yourself. With your own custom design power bank you can actually improve or upgrade it with time. A couple of new batteries every now and then will keep enhancing you power bank’s charge limit or ‘juice’.
