Xoopar Solid Smile – a slim power bank for the back of your phone, with your logo
The Xoopar Solid Smile is a card-sized silver power bank just 9 mm thick. In the product images it is attached directly to the back of the phone, where it charges the phone wirelessly – so the phone can be held and used as normal at the same time. When needed, it can also charge via a USB-C cable at up to 20 W. A small digital display on the front shows the remaining charge as a percentage. If you are looking for business gifts that feel modern and get used every day, Solid Smile is a stylish choice.
Wireless or by cable
Solid Smile measures 101 × 66.6 × 9 mm – roughly the size of the back of a phone, so it does not make the phone bulky. For wireless charging, place the power bank on the back of the phone; this requires a phone that supports wireless charging. For faster charging, connect the phone with a USB-C cable: the manufacturer states a maximum of 20 W, and actual speed depends on the phone. The digital display shows the charge level as a percentage, so it is always clear when the power bank needs recharging. When flying, follow the airline's rules for power banks – they normally belong in hand luggage.
A design for executives and clients
The matt silver housing and rounded corners give the power bank a calm, premium look that pairs well with both light and dark phones. The slim shape fits in a jacket pocket, handbag or laptop bag. Solid Smile is a great choice for executive gifts, client relationship gifts, year-end thank-yous to partners or conference speaker gift packs. At the end of its life, take the power bank to an electronic waste collection point.
Logo branding
The logo is applied to the smooth surface of the housing. The logo price in the price table includes a 1-colour print in one position. The exact print area, the final method – pad printing or UV digital printing – and placement are confirmed before production with a digital proof, making sure the logo does not cover the display and stays easy to read. Both dark and brand-coloured logos look good on the silver surface.
