Totalpower 260 Portable Power Bank

Great product

We bought this Totalpower 260 as part of a bundle with the Totalfreeze 45 and Totalsolar 100. We found that the 260 would charge, on its own, on a sunny day in about 4 hours by the solar 100 which I thought very impressive. The wonderful thing is you can charge this pack AND run the totalfreeze 45 fridge during the day AND gain enough charge to run the fridge throughout the night and keep going the next day again back on solar and charging. This is a game changer in being off grid. If you have sun or even some cloud it keeps on going. I tested this myself but there are caveats to observe in my tests, one is I ran the fridge set to 4c, I have not tried it in freezer mode (say-18c) as we don't want that and would take more power to maintain such a low temperature no doubt, we just needed a reliable 4c or thereabout for our food stuff whilst camping off grid for days on end. I connected the solar panel to the 100 watt USB-C port input of the 260 to ensure as much power was supplied as possible by the solar 100 to the 260, especially when the totalfreeze 45 compressor wasn't running due to being at the pre-set temperature I programmed, it being at a minimum fridge power drain. Additionally, you need to ensure the 260 power pack doesn't get too hot! I found that when we had a very hot day (32c) and having the battery in the solar 100 zipper pouch it was tight against the panel and after a couple of hours got too hot and shut itself down. (no doubt a fail safe feature) This stopped the supply to the fridge and was obviously not acceptable. I re-tested the set up the next day with the 260 out on the ground within shade and all was well. I am sure in more normal daytime temperatures this overheating issue wouldn't arise and you could stay panel pouch mounted. There is warning about overheating in the instructions and something to be mindful of in your particular camping set up.
I have not been able to verify the power packs claimed 252 watt, 14Ah power delivery capability but have no reason to doubt the quoted figures.

Fridge supply (the 12 Volt cigar lighter socket is used for this) ;- Low power drain by an electric fridge is absolutely crucial and from what I have seen in the general marketplace, 30-40 watts of drain by a compressor fridge (Totalfreeze 35, 45 & 55) is exceptional in the marketplace. At 12 volts 40 watts equals 3.33 Amperes, at 30 watts it would be 2.5 Amperes. This is about as low as you could expect to achieve using a compressor. 50, 60 watts or more being quoted by other makers in sometimes cheaper units might not sound like too much more but it is critical when you are trying to run off grid on a one battery and one solar panel arrangement, Totalcool seem to me to have the lowest power consumption in the marketplace. One last point, the 260 comes with a USB-C to USB-C charging lead only, you don't get a mains charging adaptor. If you wish to charge it without using a solar panel and try to use a standard phone charger you will NOT get enough current to charge it in a sensible time frame, if at all. It might take days and days. If you wish to charge in a reasonable time buy a 20 watt or more PD (power delivery) USB-C capable charger. All in all I am very impressed with Totalcool, their products and service.

great bit of kit works well

Lovely item ideal when travelling.

A priori il devrait fonctionner. Je trouve que la charge est longue. De fait j'apprécierais presque mieux les anciens power totalcool. Mais c'est une affaire de besoin. Je verrai mieuxaprèsune utilisation
