Determining whether you have the correct phone charger used to be no big deal. I studied power charging for a few years and found that most of the charging blocks that are supplied with phones delivered the proper charge. This properly matched charger provided, at no extra cost, the exact supply of volts and watts that the phone needed for optimal charging. (The volts and watts of each power block are printed on the sides of the blocks, in miniscule letters.)

Unfortunately, a current trend of manufacturers is to withhold the charging block from the purchased phone, as noted in the later sidebar “Who’s on (or off) the no-charger bandwagon?”

Behind this no-charger strategy is the assumption that you already have a compatible charger from a previous device. Even if you have an older charger you can use, the reality is that you won’t get the benefits of the newest, fast-charging technologies. Yes, you can probably use your existing (lower powered) charging blocks on your new phone — but your phone may not receive the quick-and-complete charging you expect.

The bottom line is that you may have an added expense for a phone charger. Be sure to check out whether your phone comes supplied with the fast-charging option and matching charger. If not, plan to buy one.
