Who Should Get This?
Once you know the pain of a dead phone in the middle of the day, you know a portable charger is definitely a necessity.
Whether you work long days and simply can't make it through on one charge, use your phone frequently while on the job such as for video conference calls, or frequently head out where there isn't backup power such as any outdoor recreation activities, a power bank will keep you in the clear.
The extra battery life means you won't be chained to a nearby electrical outlet or have to sacrifice your tunes on a long commute.
We all know it's better to be over prepared than underprepared. If you've somehow managed to avoid a battery crisis with your phone up until this point, keep in mind this won't be the case forever, and you don't want to be caught off guard!
Even getting a small backup is better than having nothing at all.
Power Bank for iPhone X: What to Consider
The most important thing about a power bank is its capacity. The larger this number, the more charges it can provide to your iPhone, which has a battery about 2700mAh big. This means you'll need at least that much for a single backup charge, and around twice that for two charges, and so on.
However, due to the fact that electricity isn't 100% efficient when charging your phone, keep in mind that you may need slightly more capacity to get the number of charges you want.
iPhone X supports wireless and quick charging features, both of which are extremely useful on a day to day basis. While every power bank should include a standard USB port for connecting the USB-to-lightning cable that your phone comes with, many also support these advanced modes and you should check to see if your bank of choice has an upgraded model with one or both features.
Form factor can be extremely important when purchasing a power bank. If you plan to leave it in your car, for the most part, you might not mind a heavy bank. However, if it's going to travel with you, perhaps in a purse, airplane carry-on, or backpack, a slim and light model will be a much better choice.
Additionally, look for power banks that include charge remaining indicators. These are often in the form of a strip of LEDs to indicate 0-25, 26-50, 51-75 and 75-100 percent battery remaining. This is extremely useful for keeping track of exactly how much backup power you have.

Power Bank Caring Tips & Tricks
While having a power bank will certainly keep you in the clear, you should also practice good battery care with your phone so that it will have a longer lifespan and be better at holding a charge.
The most basic advice is to avoid extreme temperatures and always have the latest software updates, and remove cases that get too warm while your phone is charging as this can cause battery damage. Never charge your iPhone X overnight, it's bad for the battery to leave it plugged in for hours and hours at 100% while you continue sleeping.
There are also settings you can change to adjust your battery performance. For some of Apple's official tips, check out their article on the matter. Alternatively, you can follow this guide from Video Gadgets Journal specifically for improving battery life on the iPhone X, which contains some more obscure tricks.
Battery life is unreliable, but a power bank isn't. Hopefully, we've been able to help you along the way to a great new backup, whether that's in the form of a giant chunk of power or a smaller, single charge backup, or something more suited to your individual needs.
