The Moto G7 Power costs $249 (£179, or about AU$420) and is available for preorder from Motorola now. The full release comes March 22.

Best Buy is also offering the the G7 Power for preorder at the same price, though you also have the option of saving $50 if you activate it with a carrier at the time of purchase.

Finally, a third-party seller, Mobiles International LLC, has the international, 64GB version of the G7 Power for $269.99, and it appears to be available immediately. Take note, however, that it's a GSM-only model, meaning in the US it will work only with AT&T and T-Mobile. The US versions (like those from Best Buy and Motorola) support CDMA networks as well, so they'll work with Sprint and Verizon as well.

The the G7 Play is cheaper at $199 (£149, or about AU$280). Preorders for that begin March 29, and it will go on sale April 5.

Though they all run Android 9.0, are water-repellent and have the same processor as the Moto G7, both phones only have one rear camera, while the G7 has two. The G7 Play also has a smaller, lower-resolution 5.7-inch display while the G7 Power has a 6.2-inch screen.

The G7 Power's battery is the highest-capacity of the bunch. At an impressive 5,000 mAh, it's expected to yield a long battery runtime. In comparison, the G7 Play has a 3,000-mAh battery.
