I review tech for a living: 9 top-rated gadgets under $50 and on sale at Amazon now

My team reviewed the EarFun Air Pro 3 last year, when we awarded a 4-star rating to these budget earbuds. The sound quality is strong for the money, while the ANC and battery life are excellent. I own the EarFun Air Pro 4s (also on sale for $67 at Amazon) and I would recommend these instead if you can stretch the extra $20, as they're phenomenal and won 4.5 stars from us. You won't regret the Air Pro 3s, though, as they're still brilliant buds.

"Proof that gaming performance can come cheap" is how we described this mouse in our 4-star Redragon M916 review. This brilliant little gaming mouse is extremely light and offers excellent gaming features for the money, including adjustable DPI up to 8K. This deal is for Prime Members only.

I tested the JBL Go 4 personally last year and was impressed by how well this speaker performed given its size, awarding a 4-star score. It offers decent sound quality, high levels of waterproofing, multi-point connectivity and is super portable. It's ideal for slipping into your bag to soundtrack spontaneous gatherings or for playing music while you study.

I won't lie, this one took us a little by surprise in our GameSir G7 SE review. We awarded this controller 4.5 stars and our Editor's Choice award. It's a fantastic pad for the money, with hall effect triggers and sticks (so no stick drift); excellent companion software and customization options; and a lightweight but sturdy build. "Better than an official gamepad" was our conclusion.

Alright, full disclosure, my team hasn't reviewed this. However, I own one of these chargers and honestly, I don't go anywhere without it. It's so useful having three charging points, so I can charge all my devices simultaneously from one power outlet when on the go. This version is 65W: so good for phones, gadgets, tablets and small laptops like a Chromebook or MacBook Air. I own the 100W version, which is pricer (although currently $10 off), but it can charge my full-size MacBook Pro.

We're big fans of the Gamakay TK75, awarding 4 stars to the Pro model after our testing. This model is slightly cheaper, using Gateron switches rather than Gamakay's own brilliant switches. Absolutely nothing wrong with a Gateron switch, though, especially for $34. And besides, this deck is hot swappable, so you can change switches anyway! This board is perfect for typing and productivity — ideal for anyone heading back to school.

Another keyboard, and one of my team's favorite gaming decks. The Lemokey X1 is a budget gaming keyboard from Lemokey — that's Keychron's gaming-focused sub-brand. This budget board offers great gaming performance, is good to type on and is built very well given its minimal price tag. Gamers on a budget, look no further.

Where would we be without our air fryers? I use mine day in, day out. We tested this Corsori Mini Air Fryer's bigger sibling, the Cosori Dual Basket, awarding 4 stars. This smaller version is great if you need to save space, maybe in a dorm or small/shared kitchen!

We bestowed upon the Amazfit Band 7 our 4.5-star Editor's Choice award when we tested it last year. We asked: "why spend $150 when the Amazfit Band 7 is right here?" A lovely display with great battery life; tons of fitness, health and sleep tracking features; plus a minimal, lightweight design... all for $37. What's not to love?
