Groove 20000mAH Powerbank Charger

Groove 20000mAH Powerbank Charger

The Groov-e 20,000mAh Powerbank Charger is the sort of accessory that becomes extremely important at precisely the moment you realise your phone is sitting on 4%. Packing a hefty 20,000mAh lithium-polymer battery, three charging outputs and up to 15W total output, this high-capacity portable power bank is built to keep phones, tablets, e-readers, GPS units and other USB-powered gadgets alive when a wall socket is nowhere to be found.

For musicians, that makes it a particularly handy bit of kit to have knocking around in a gig bag, backpack or touring case. Phones have become everything from setlist holders and tuners to backing-track machines, recorders, navigation systems and the device containing the address of tonight's venue. Watching the battery icon turn red twenty minutes before load-in is an experience best avoided.

The headline feature is that substantial 20,000mAh capacity. Groov-e estimates that, depending on the device and battery size, there's enough stored power for around 6–8 smartphone charges, 2–3 tablet charges, 4–6 e-reader charges or 6–8 GPS charges. Real-world results will naturally vary depending on the device, battery condition and how it's being used, but there's considerably more juice available here than you'd get from a small emergency power bank.

Better still, the Groov-e GVCH20000 can charge multiple devices. There are three charging outputs in total: two USB-A ports and one USB-C port. So if your phone needs power while somebody else is attempting to revive another device, you don't necessarily need to start negotiating ownership of the charger.

Each USB-A output is rated at 5V/3A, while the USB-C output also provides 5V/3A. Maximum combined output is 5V/3A or 15W, making this a practical everyday portable charger for compatible smartphones and USB-powered devices.

It's worth noting that the USB-C connection isn't merely an output. The power bank itself can be recharged using USB-C or Micro-USB input, giving you some welcome flexibility when it comes to cables. A complete recharge takes approximately 10.5–11 hours, so plugging it in overnight is the sensible move before travelling, heading to a festival or embarking on a long day of rehearsals and gigs.

There's also a built-in power level indicator, so you can check how much reserve power you've actually got rather than relying on optimism. That's particularly useful with a 20,000mAh battery because this is the sort of power bank you're likely to use across several devices or several days between charges.

Groov-e has also included an automatic safety cut-off, adding protection during everyday charging. Combined with the lithium-polymer battery and straightforward USB connectivity, it makes the GVCH20000 a practical grab-and-go power solution for work, commuting, travel, college, rehearsals and festivals.

And yes, we're putting a power bank in among all the guitars and music gear. But think about it: your tuner app needs a phone. Your digital setlist needs a phone. Your gig photos need a phone. The group chat containing the message explaining that rehearsal was moved to another studio needs a phone.

Suddenly 20,000mAh starts looking suspiciously like musical equipment.
