View DealIn my UGreen Uno Charger 100W review, I applauded the model's trustworthy and speedy performance, its multi-device charging capabilities, and, of course, its fun and emotive display. Speaking of the display, I love how the Uno Charger makes faces at me throughout the day, which shift depending on device charging status. For instance, it has an eating animation when mid-way through charging or displays a ‘cool’ emoji when your device hits 100%. I know, it really doesn't take much to amuse me. But making such a mundane task somewhat entertaining is a grand feat in itself.I've used this model every day since reviewing it in January 2025, and it's never let me down. Its 100W maximum output is plenty for my MacBook Air or Xiaomi 17, and I can even charge a handful of devices — like gaming controllers and wireless headphones — simultaneously. Even after throwing it in my bag countless times and using it so regularly, I've seen no degradation in terms of performance or cosmetics, so at such a low price, this model is an absolute must-buy.More Prime Day deals in the USAmazon Devices: Fire Sticks & Echo from $18Amazon Haul: viral gadgets, tech & appliances from $1.36Apple: MacBooks, AirPods & AirTags from $28Cheap TVs: smart TVs from $69.99Headphones: 50% off Beats, Bose & SamsungLaptops: Apple, HP & Dell from $199Mattresses: Sealy, Serta & more from $89Smartwatches: up to 36% off Garmin & AppleVacuums: Dyson, Shark & Bissell from $49More Prime Day deals in the UKAmazon Prime: get a 30-day free trialAmazon Devices: up to 67% off Fire, Ring & BlinkAmazon Haul: extra 15% off for Prime membersAppliances: up to 40% off Ninja & De'LonghiBeauty: up to 60% off Philips & Oral-BEssentials: cleaning & groceries from £2Fashion: up to 50% offGaming: record-low Nintendo Switch 2Headphones: up to 50% off Anker & SonyLaptops: up to £800 off Microsoft & AsusTablets: up to 50% off Fire tabletsTVs: from £129.99Vacuums: up to 50% off Shark & DysonWearables: Samsung & Oura from £31
