Our favourite, huge power bank for the Steam Deck is down to £52/$80 from Amazon
The Ugreen Nexode Retractable is our most favouritest Steam Deck power bank, as James decreed with his testing, and by spending his hard-earned money on it – and if it's good enough to earn a top recommendation here, then it's worth you giving it a look over. £52 is a good price for this unit from Amazon, and a price it strangely wasn't during Amazon's Spring Sale last week.
In the USA, it's $80 - a 20% reduction on its $100 MSRP. It has sat at this price for the last couple of weeks, and has gone for less in the past, but it's still a reasonable deal.
