The Aukey PB-Y7 is a fresh take on the PB-T11, which we reviewed a few years ago.

Like its predecessor, it is a compact laptop power bank that comes with a whopping 30Ah capacity and is housed in a solid ABS chassis that will withstand scratches (but probably not falling on a hard concrete floor).

At $75.99, we’d usually baulk at recommending it to you. However, ahead of Amazon Prime Day, it's available at $20 off and coupon WMPYADFW will drop the price even further to $40.79. You will need to hurry, though, as the offer ends tonight at 23:59 PDT.

The biggest difference between the Y7 and the T11 is the fact the former comes with power delivery, allowing it to deliver up to 30W of power to a laptop or tablet. Just bear in mind that not all devices will be compatible and incompatible models are likely to charge at a slower pace.

The PB-Y7 comes with a four year warranty and weighs only 553g with dimensions of 150 x 84 x 29mm, making it small enough to fit into a large pocket. There’s also a pair of USB Type-A ports that are compatible with Quick Charge 3.0, plus a quartet of LEDs that indicate how much juice is left.

If there’s one thing we’d change, it would be the fact it comes with a microUSB port for charging. It was acceptable a few years back, but feels antiquated in 2020.
