Know Charging at a Glance – with built-in digital ammeter and chip
A digital ammeter displays real-time ampere readings while an internal chip stabilises output to prevent large current fluctuations. Readings help confirm how much current each device is receiving under different light conditions.
Immediate feedback shows when repositioning gives the best sun exposure, helping to maximise charging efficiency on the move.
Faster Phone Top-ups – thanks to USB-A and USB-C with Smart IC
USB-A supplies 5V/2.4A and USB-C supplies 5V/3A, with an intelligent chip that identifies device needs and negotiates optimal current. Both ports together deliver up to 5V/4A total, sharing available current automatically.
Charge a phone quickly at its supported rate or share power between two devices without manual configuration.
Sturdy Outdoor Carrying – with N-type panels and IP44 protection
N-type panels offer higher conversion efficiency up to 25.4%, while an IP44 rating resists light rain and wet fog. Stainless-steel eyelets on each corner and a zippered pocket provide secure attachment and safe storage for a phone or cable.
High-efficiency cells and rugged attachment points make the panel practical for days out, though direct contact with water should be avoided during charging.
