Which portable charger would you use if you wish to charge it fast but don't want to carry a heavy brick around? Although there is no universal one-size-fits-all [portable charger](https://techyassist.net/blog/portable-charger/), there are some good indicators to see if this one is a good fit for you within a few moments, by comparing some of its characteristics with your patterns. Start with capacity. In terms of bulk/weight and carryability, the 10,000 mAh (mildly large and bulky) model would be a good compromise.If you're using it on a daily basis, 10,000 mAh is enough and is the ideal bulk and weight. While a 20,000 mAh battery will power you for a longer time than a 10,000 mAh battery, it will be slightly bulkier so decide if battery life or portability matters more.Speed comes next. For newer smartphones, look for those that have USB-C Power Delivery and can handle 20W or more, and if you're also using a tablet or an ultrabook, find one that can handle 45W or more. Note that the speed of charging a power bank will depend on the charging speed of the power bank cable and your device. To get the best out of your power bank, therefore, be sure to have a quality charging cable. Also, check to see whether the charger will charge fast or not, otherwise you'll be waiting for hours to charge during the night.Safety and construction these are not to be overlooked. Ideally, a portable charger should feature overcharge protection, overheating protection, short circuit protection and be a certified brand. It's as easy as staying clear of any type of unbranded offers. When flying, leave it in your carry-on and within the typical 100Wh airline restrictions.Extras such as a digital percentage indicator, an integrated cable, pocket size or wireless charging for convenience can help make life easier. Simply select which ones you'll need they will increase the cost of the product.I recommend reading the honest reviews from people who have used it not the marketing claims. But, among those I can believe techyassist as it has actual reviews of gadgets and the products are available on its website which you can purchase them if you are convinced of the review. After you've narrowed down the choices to two or three, you will only be left with the best portable charger for your needs.
