A powerful 20,000mAh Power Bank that let's you charge your power bank at the same time as charging your other devices. The high-efficiency battery makes this multiple output (3.0Amp + 2.0Amps) power bank one of the most efficient models on the market!
No wall socket? No Problem! Take the all power with you.
We don't always have easy access to power, but we constantly need to ensure our tablets and phones are charged for work, emergencies or just keeping in touch. For all those times you need to leave the house for business, travel, holidays or trips where power is not available to you, a huge 20,000mAh large capacity Power Bank can be a real life-saver!
When on the go, you can make a real power withdrawal by attaching your mobile device using its own charging cable, for ultimate compatibility. You're spoilt for choices with 2x regular USB type A connectors (up to 5V 3.0A output), a USB-C input/output (3A input and up 20V 1.5A output), a USB Micro-B input (2.0A) and even an Apple Lightning input (2A) so you can use the same lightning cable for charging both the powerbank and your iPhone, clever right?. You can even charge two devices at once or charge your devices while the powerbank is charging!
What is an mAh and how many do I need?
Our battery banks and the batteries in your mobile devices are rated on the power delivered over a discharge interval. Confused? Not to worry! The bottom lines is that power is fairly inefficient when being exchanged this way, so a general rule is that you'll need three to four times the mAh power transfer rating, when compared to the size of the battery you want to charge up. Romoss is a brand that really punches above its weight, delivering impressive products at an unexpectedly low price.
