Most tech costs a fair chunk of change (the PS5 Pro and iPad Pro jump to mind), but some smaller electronics are (almost) as exciting. Now that Cyber Monday is here, we've found dozens of deals on inexpensive electronics and accessories that cost less than 50. Unlike other lists you may find today, this one is made up of items we've tested, reviewed or otherwise recommend in our buying and gift guides -- so we think they're actually worth your money. Amazon Echo Pop (2023) for 18 ( 22 off): Amazon's smallest Echo will fit in any room in your home, so Alexa can add things to your shopping list, set a timer, or answer questions (like "What's a bomb cyclone?" or "Who is Penelope Cruz married to?") from anywhere. Anker Nano Charger 30W USB-C for 13 ( 7 off): This compact 30-watt wall charger is smaller than others of its wattage and can speedily juice up an iPhone or Android handset. Anker is one of Engadget's most recommended accessory brands and this is the model we picked for our fast charger guide. Get the same deal at Anker with an auto-applied code. Anker Nano power bank with built-in USB-C connector for 16 ( 4 off): It's the size of an old-timey lipstick case but packs enough juice (and its own USB-C plug) to get a dying smartphone back in service with at least a half charge.

The expensive tech gets all the attention -- thousand-dollar phones and 500 tablets. But the supporting players, the cables and batteries and chargers that make those devices work properly, are just as important. Right now for Black Friday, many of those smaller gadgets are on sale for less than 50 even after the day has passed. And there are even some standalone devices like earbuds and smart speakers that fall well below the threshold. We've tested scads of these smaller, less expensive tech for Engadget buying guides, including the best power banks, iPad accessories, smart plugs and microSD cards. Here, we've gathered up all the Black Friday tech deals under 50 that you can still get on gadgets we recommend. Amazon Echo Pop (2023) for 18 ( 22 off): Amazon's smallest Echo will fit in any room in your home, so Alexa can add things to your shopping list, set a timer, or answer questions (like "What's a bomb cyclone?" or "Who is Penelope Cruz married to?") from anywhere.

When it comes to new tech, 50 doesn't get you a lot-- except perhaps during Black Friday sales. Surprisingly, quite a few of the smaller electronics and accessories we recommend are currently on sale right now for less than 50. These deals include picks from our guides to accessories guides, portable batteries, budget earbuds and smart speakers. Everything on this list has earned the Engadget nod of approval -- like Anker's Nano charger ( 13), Belkin's AirTag holder ( 15) and PopSocket phone grips ( 15). These picks come from stuff we tested for our reviews and buying guides or from personal use and brands we know to be reputable -- so you don't have to guess whether these Black Friday tech deals are worth your (less than) 50.

If you're in the same boat, you'll be happy to know that there are plenty of reviewer-approved gadgets and goodies available for $50 or less.

When Amazon introduced its 2nd-generation Echo Buds in 2021, the company redesigned them to address nearly every issue with its first attempt. They had true active noise cancellation (ANC), better sound and a smaller size. Amazon took a much different approach for its third version, opting to move from mid-range to a low-cost model with an all-new design that covers most of the basic features you'd expect. As always, the Alexa faithful will get the most out of the new $50 Echo Buds, but in a lot of ways you could argue a budget model that does well with the essentials is where Amazon should've been all along. While the first two iterations of the Echo Buds had similar designs, Amazon completely changed things up for the third generation.

We present LLM-Blender, an ensembling framework designed to attain consistently superior performance by leveraging the diverse strengths of multiple open-source large language models (LLMs). Our framework consists of two modules: PairRanker and GenFuser, addressing the observation that optimal LLMs for different examples can significantly vary. PairRanker employs a specialized pairwise comparison method to distinguish subtle differences between candidate outputs. It jointly encodes the input text and a pair of candidates, using cross-attention encoders to determine the superior one. Our results demonstrate that PairRanker exhibits the highest correlation with ChatGPT-based ranking. Then, GenFuser aims to merge the top-ranked candidates, generating an improved output by capitalizing on their strengths and mitigating their weaknesses. To facilitate large-scale evaluation, we introduce a benchmark dataset, MixInstruct, which is a mixture of multiple instruction datasets featuring oracle pairwise comparisons. Our LLM-Blender significantly outperform individual LLMs and baseline methods across various metrics, establishing a substantial performance gap.

Anker, which made its name building device batteries and chargers, is now making gear for all of the devices you own. Or at least all of the devices in your home, since it just unveiled its Solix home energy system, which can be bolted onto existing or new domestic solar setups. Like many other home battery companies out there, Solix is scalable, with the smallest unit sized at 5kWh – enough for a few hours backup power – all the way up to 180kWh. It won't arrive until 2024 but, when it does, it'll be paired with an EV charging system Anker is presently cooking up. The company is no stranger to this world, since it already builds small solar and battery sets for off-road types. But it's pleasing to see it also entering the home battery market which, Tesla aside, is full of companies that don't have as big a presence in the consumer space.

A series of datasets and models have been proposed for summaries generated for well-formatted documents such as news articles. Dialogue summaries, however, have been under explored. In this paper, we present the first dataset with fine-grained factual error annotations named DIASUMFACT. We define fine-grained factual error detection as a sentence-level multi-label classification problem, and we evaluate two state-of-the-art (SOTA) models on our dataset. Both models yield sub-optimal results, with a macro-averaged F1 score of around 0.25 over 6 error classes. We further propose an unsupervised model ENDERANKER via candidate ranking using pretrained encoder-decoder models. Our model performs on par with the SOTA models while requiring fewer resources. These observations confirm the challenges in detecting factual errors from dialogue summaries, which call for further studies, for which our dataset and results offer a solid foundation.
