The Aqua Trek + waterproof camping phone charger is twice the size, capacity and weight of the standard Aqua Trek. Once charged will retain its capacity for months, ready for when needed, as part of a survival kit or a reassuring backup charger for boats, festivals and camping. We have also left one in the water for 1 month, flashing an SOS, it still works. Our Aqua Trek Power Banks have been up Kilimanjaro, Everest base, across the Atlantic and supplied to the military.
Our Special offer Travel and Trek package includes a folding Solar Panel charger, enabling indefinite off grid power. The 20 Ah battery would be enough to charge a standard smartphone 8 + times or a Tablet 4+ charges.
This waterproof portable rechargeable battery is uniquely suited to outdoor activities. It has a bright LED torch with an SOS facility, should the need arise, a potentially crucial piece of safety equipment, particularly in a marine environment. The premium grade 'A' 18000mAh Samsung batteries hold a full charge for up to a year and have very little loss on DC transfer, giving the maximum number of charges for a given capacity.
