I bought a Mecer Lithium Trolley and I am impressed!

Unboxing this 1000w lithium trolley is amazing for keeping essential stuff on It has solar input that comes in handy in the daytime and a LifePO4 Battery with Capacity: 25.6V-50AH(1280WH) The display gives you a great idea of all that's going on, like power usage etc. It's also got 2000 cycles so it will last you a good amount of years https://www.idoza.co.za
