Smaller yet useful tech accessories — batteries, cables, phone cases and so on — are what keep the big ticket items working for us. And Amazon’s Prime Day sale is an excellent time to stock up on these humble sidekicks. Only problem is, not everything on Amazon’s site passes muster, and the cheaper stuff can be particularly questionable.

Luckily, we’ve tested plenty of smaller devices for one buyer’s guide or another, so we think any items picked from this list should serve you well. Here are the best Prime Day Tech deals under $50.

If you’ve got $25 and some change in an account somewhere, you can get something decent from Amazon’s sale (particularly if you’re a Prime member and don’t have to pay for shipping). We searched for the most useful tech we could find and came up with smart home speakers, cameras and plugs, plus a mouse, a streaming stick and some cable — all for less than $25.
