(Last Updated On: June 30, 2020)

OnePlus has come a long way since their first phone and it’s quite amazing that they were able to break into the US market and ultimately have their phone be sold by a major carrier. That carrier being T-Mobile.

Of course, it didn’t just happen out of nowhere, OnePlus smartphones have always been about keeping up with the larger competitors, especially Samsung, and at the same time surpassing them in some way. Most notably the performance of their phones is amazing due to the amount of RAM that they use, and recently, with the OnePlus 7, the addition of a 120Hz refreshing rate screen gives a great user experience.

The OnePlus 7, 7 Pro, and 7T, all offer the best the brand has to offer. That said, going with the best speed with a 12GB RAM option and a higher refresh rate screen that’ll make a regular 60Hz screen seem slow, battery power can be burned into quickly.

Being able to fast charge your OnePlus 7 with a power bank can let you continue using the awesome things that this phone features. So we’ve compiled together a few chargers that you can use.

Power Banks in this Guide:

Aukey 10,000mAh 18W USB-C Power Delivery Power Bank

When choosing a power bank or your OnePlus smartphone, you’re going to want to make sure of two things. One is that it has enough power capacity to charge your phone to full power at least once. The other is that it features USB-C Power Delivery to at least fast charge the phone at 15W.

Also, the base OnePlus 7 has a battery of 3,700mAh, the OnePlus 7T has a 3,800mAh battery and the top tier OnePlus 7 Pro has a 4,000mAh battery.

This Aukey power bank has a 10,000mAh power capacity, which is enough for charging the OnePlus 7 Pro with the largest battery, about 1.5 times to its full power. Charging the other two model phones may result in about two full charges.

Charging power from this power bank is great for a mid-range portable charger. It has three ports, with one 18W USB-C Power Delivery port, a Quick Charge port, and a standard port.

In this case, you’re going to want to use the PD port to fast charge your OnePlus phone, as the OnePlus phone is not compatible with Quick Charge, but many other Android phones are.

The form factor of this power bank is slim with a thickness of only 0.6 inches.

With this much power, you’re able to charge an OnePlus 7 to full power about four times without having to recharge the power bank. So there’s less worry about the power bank running out of power. Charging other devices to full power at the same time while you’re charging your phone is also possible because of how much power there is to use.

There are also three output ports. A single Quick Charge port, a PD port with 18W of power, and a standard USB-A port.

This RAVPower charger also has three input ports that you can use to recharge it. One is the USB-C port that can also be used to recharge the power bank. The other two are a Micro-USB input port, and a rare Lightning input port that is rarely used with power banks.

This Xcentz portable charger has a very low capacity of 5,000mAh. It’s only going to be enough to charge either the OnePlus 7, 7 Pro or the OnePlus 7T to full power only once. So this charger only has a single day’s worth of power if you’re charging your OnePlus phone from empty or near empty.

Despite its low capacity, charging power is not lacking and that’s because it has an 18W Power Delivery port and a USB-A Quick Charge port. That’s two fast charging technologies with a power bank that has a length of 3 inches and a thickness of only 1 inch.

There’s the 20,000mAh power capacity that can prove useful for charging the OnePlus phone a few times without needing a recharge for a few days.
