Power to go:

‘Supreme’ power pack series

When you’re travelling on business from A to B, your smartphone battery is often pushed to the limits: You use your smartphone for your digital flight ticket that you show at the airport; you check your presentation one last time before your business meeting; and you check your customer data, make phone calls and, depending on the country or city, take souvenir photos. And when you’re on holiday, the battery situation is no different: If you’re visiting distant places, you’re quite grateful for holiday apps and offline tickets.

Nowadays we are constantly connected with our smartphone. What we don’t need is an empty battery. Unfortunately, charging facilities are not available everywhere – dependency on a power socket to charge our mobile devices is not ideal. Hama has the socket for when you’re on the go: the ‘Supreme’ series of powerful power packs.

Powerful, but slim

Goodbye chunky power pack, hello cool, slim design: This battery pack incorporates innovative high-density lithium polymer cells. The advantage: a compact and slim power pack. This design foregoes round batteries and uses a square structure that takes up less space in the housing. Thanks to the high-density cells, the power pack is up to 40 percent smaller and up to 20 percent lighter than power packs with conventional lithium ion cells. So when you’re on a photo tour, outdoor trek or business trip, the mobile charger with a capacity of 5,000 mAh can fit easily into your jacket or trouser pocket. The two power packs with the highest capacity easily fit into a handbag or belt pouch, or in a backpack or laptop bag.

New power for all

Start off as you mean to go on, with fresh power: With the ‘Supreme’ series, all mobile devices – be they smartphones, fitness watches or speakers – will have a full battery again in no time. The charging capacity of the different power packs is sufficient to charge a smartphone several times, depending on the smartphone’s battery capacity. Charging adjusts to every mobile device, so that no damage is caused to your battery.

Supreme 10HD Fully charges an iPhone XS almost four times
Supreme 20HD ully charges an iPhone XS almost seven times

The LED capacity indicator shows the remaining power in the power pack. Four small lights indicate whether 25, 50, 75 or 100 percent power is still available. This means you can plan use of your smartphone perfectly!

Hard core, soft shell

The power pack has a classic business look in black, so there’s no need for it to remain hidden in your handbag or jacket. The soft-touch surface gives the battery pack a touch of class and feels pleasantly powdery. The external batteries always look good, as fingermarks are barely visible on the special finish.

Full battery – full safety

You often hear about batteries exploding and setting fire to the home. You can trust power packs from Hama: They are thoroughly tested by Hama’s internal quality assurance department. Furthermore, the ‘Supremes’ are TÜV-certified. This guarantees compliance with the strict safety standards applicable in Germany. Overcharge protection automatically stops the charging process when the battery is full, which means that the battery cannot swell and explode. Deep discharge protection prevents the battery from completely discharging to zero so that nothing works any more. It is also short circuit-proof – so if something is not quite right with your fuses, the power pack remains unaffected.
