00:00If you've ever pulled apart an old power bank or built your own battery pack,
00:03you already know the pain, you need a charger board that won't cook your cells,
00:07and a tester that actually tells you the truth about that 9,900 mAh battery you bought online.
00:13So I went digging, compared a bunch of listings, and pulled together the top 5
00:1918650 lithium battery charging and tester modules that people are actually buying right now.
00:24Let's get into it.
00:26First up is the 1A18650 lithium battery protection board that comes in Type-C,
00:31Micro, and Mini-USB flavors, built around the classic TP4056 chip with a proper protection
00:37circuit built in. That protection plate is the whole point here, it handles overcharge,
00:42over-discharge, and short circuit, so you're not babysitting your battery.
00:46This bundle runs about $23.57, and it's already moved nearly 5,000 units with a 4.9 rating.
00:54If you're wiring up multiple projects and want one connector type per build,
00:58having all three options on hand is honestly a lifesaver.
01:02Next is the one I'd call the most genuinely useful tool on this list,
01:06the 2-channel 18650 capacity tester.
01:10This thing measures milliamp hours, milliwatt hours, and internal resistance,
01:14and it does two cells at once over a Type-C connection.
01:18That internal resistance reading is the real hero, because it tells you instantly whether a
01:22salvaged cell still has life in it or belongs in the recycling bin.
01:26At $69.18 it's the priciest pick here, but with almost 5,000 sold and a 4.8 rating,
01:33it pays for itself the first time it saves you from building a pack out of dead cells.
01:37Now if you just want to dip a toe in, product 3 is the single TP4056 Type-C charging board,
01:43and it is $1.29.
01:46That's it.
01:475 volts, 1 amp, with both charging and protection functions on the same little board.
01:53You can grab one to test the waters or order the 10-pack if you already know you love it.
01:58It's got a 4.9 rating across 4,500 orders, and honestly, at this price there's no reason
02:04not to keep a couple in your parts drawer for the next time a gadget's charging circuit dies on you.
02:09Coming in at number 4 is the 10-piece set of TP4056 charging boards with your choice of mini,
02:15micro, or Type-C input, all with protection built in.
02:18The appeal here is simple, buying in bulk.
02:22$26.68 for 10 boards works out to under $3 each, and if you're the kind of person who's
02:28always got three half-finished projects on the bench, you'll burn through these fast.
02:32Nearly 4,500 sold and a 4.9 rating tells you the quality control is holding up,
02:37which matters a lot when you're trusting these with lithium cells.
02:41And rounding things out is the flexible 1 or 20-piece TP4056 charger module,
02:46again with Type-C, micro, and mini-USB options and full protection circuitry.
02:51What I like about this listing is the 20-pack option, at $21.17 you're paying roughly a dollar
02:57a board, which is about as cheap as this gets without sacrificing the protection I see.
03:02Over 4,000 sold, 4.9 stars.
03:06If you run a repair bench, teach electronics, or just hate reordering parts,
03:10this is the smart bolt buy of the bunch.
03:13All the links are down in the description, so go check the current prices,
03:17they move around a lot on these.
