This video reviews seven inexpensive and intriguing electronic products sourced from the online marketplace AliExpress. The host conducts hands-on testing, teardowns, and analysis to evaluate each product's claims and determine if they are valuable "hidden gems" or simply "garbage." The items tested include a portable air pump, a low-cost rotating LiDAR sensor, a turbo fan and soldering iron powered by Makita batteries, a tiny USB-C lithium battery charger, a "Rodin Coil," and a location tracker compatible with Apple's "Find My" network. The findings are largely positive, with most gadgets performing surprisingly well and offering great value. The location tracker, Makita-powered tools, and LiDAR sensor are highlighted as particularly useful. Only the Rodin Coil is dismissed due to its high price and pseudoscientific "free energy" claims.
Reviewing 7 AliExpress Gadgets: Hits and Misses
0:02:22 Portable Air Pump: A compact, rechargeable air pump that includes different nozzles, an LED light, and a vacuum function. It successfully inflated a pool float in 41 seconds and a larger mattress in just over 3 minutes. A teardown revealed a clean design and good build quality, making it a highly recommended product.
0:04:40 Low-Cost LiDAR Sensor: This rotating laser distance sensor, costing around 15€, claims a 12-meter range and good sunlight resistance. Despite a lack of English documentation, it was successfully operated by translating the Chinese datasheet with ChatGPT. Testing confirmed it delivers accurate distance values up to its advertised range, making it a great value for hobbyist projects.
0:06:38 Makita-Powered Portable Tools: The video showcases a powerful turbo fan and a portable soldering iron, both designed to run on standard Makita power tool batteries. This design eliminates the need for proprietary batteries. On a 5Ah battery, the fan runs for about 45 minutes and the soldering iron for an hour. Both are deemed practical and well-made.
0:08:25 The Rodin Coil: An expensive copper coil marketed as a "free energy device." The host is immediately skeptical. While testing confirms it produces a variable magnetic field, the pseudoscientific claims and high price lead to a "thumbs down" rating.
0:09:54 Tiny USB-C Battery Charger: An extremely cheap (around 1€) and tiny board for charging 4.2V lithium batteries via USB-C. Testing confirms it uses the LP4054 IC and performs a proper constant-current, constant-voltage charge cycle. Despite the IC getting hot, its built-in thermal protection makes it a safe and recommended product for simple charging needs.
0:11:30 "Anti-Loss" Location Tracker: A low-cost alternative to an Apple AirTag that is fully compatible with Apple's "Find My" network. It pairs easily with an iPhone, allows for global tracking by leveraging the network of nearby Apple devices, and can play a sound for local discovery. Power analysis suggests a 5-6 month battery life, making it a highly effective and recommended "life safer."
