Very high quality. Small and powerful little packs of energy. Very useful as multipurpose battery for your needs. They have protection circuit, so they are ready for use on your favorite 3,7V rechargeable battery powered gadget. Nominal is 820mAh, but even if real was half, this is a good power for the size. Still not tested, but the excellent well built gives confidence.

Q: Is this CNC good for making PCB? Or better ones here on Banggood for that purpose? Thanks.

Description for this product is absolutelly wrong. No indication lights of any kind as described and no Ambient Light sensor for "switching lights at the evening". Tried to use this on my systems and the device seems dead. Didn't charge my battery despite good solar pannel input and, many hours, I did a battery discharge test and this doesn't have overdischarge protection...my 12V 1Ah battery discharged until 6V and no protection worked switching output off or disconnecting battery discharge, almost ruined my battery for trusting this device. Never had problems with Banggood electronics before, but this one was a deception.

Nice and well built small solar cell for tiny circuits, experiments and recharging of SMALL capacity batteries. But specs on description are very wrong. As measured, the device gives under direct summer sun a maximum of 6,5V, but a current of 0,035A, not 0,35A as staded on description. So, applying Ohm this means a solar panel alone can give a maximum of 0,5W, not 2W. To get 2W you would need to put 4 of these together on paralel. I bought this one for building a solar automatic garden light and I am afraid the power it gives is not enough for fully recharging the small battery during daylight. However, nice panel for the price you get.

Q: does this came with a board? can I use it with raspberry pi 4 B?

Asked by thehellboy on 2020-07-10 12:03:37

Josema8 No, you will need a driver board. Can't connect direct on a Raspberry Pi.

Q: is it waterproof?

Asked by Amorfos on 2019-03-01 09:13:19

Josema8 It's waterproof if you don't forget to seal connections. Surface of the cell is waterproof, but not the part below. Apply silicon or something to seal the wiring and naked soldering spots.

Very high quality plastic bags, rigid but not so much. Ideal for storing small pieces that can pierce regular quality plastic bags. They have a nice zip close to keep things inside. I use them to store electronics components like chips or transistors whose pins otherwise destroy normal plastic bags. Durable and very transparent. More expensive than normal bags, but worths it.

PVC shrink tube ideal for isolating your batteries, circuits or cables. This one shrinks from aprox 3cm to aprox 2cm. It's very thin, however so not recomended if heavy isolation required.

Oh, man!...these pieces are very good. Very good quality copper in flat bars. This may look like copper, but it's really gold for building your connection plates for solar energy or whatever you need a serious power transfer. Not isolated, just pure copper.

As described, ziplock bags ideal for storing all your small stuff on a safe place. Write with a permanent marker on the white bands to keep the contents well identified. The quality is good because they are medium thigh, seem durable enough and the ziplock works well.

Strong quality MC4 connectors at a decent price. Heads snap OK into bases and male snaps OK on female. No complication and the cable holding screw has a right gummy tube to guarantee isolation against splash and dust. They took a month to arrive, but I understand international commerce due to Covid crisis is collapsed, so no complaining here.

The bag is smaller than it seems, and the multiple interior cushions even let less space for your stuff. More than for carrying stuff, this bag seems more adequate for carrying photographic equipment, so this will seem small if you want this for your sport clothing and towel and so on. The sides are small expandable baga, one made out of mesh and other made out of water resistant closed nylon (I don't know why aren't both of them of water splash resistant closed nylon...). Theory is this is water repelant, but a rain cover would have been a good idea. Anyway, the sides have a hang and an elastic in the case you want to unfold and keep them hold on side without "flapping" as you move or take a curve. Not of much storage capacity, but I can't take more on my 16" bike, so I can't complain. The center storage unfolds somehow to expand the capacity, but only one side giving the "V" shape to your bag. More profitable space would be got if this expanded both sides, but well. It fits firmly by two velcro that hold on the rear bike rack and by a belt that holds on your saddle tube. This even has a belt so you can wear this bag on your shoulder when not on the bike. VERY IMPORTANT, I miss a belt or something on rear to hold the rear light, because the bag can block your actual rear light and you don't have where to place this! A reflective band is not enough to see or be seen at night or dawn... Otherwise, this fits very cool on my 16" tiny electric bike and I am happy with the product. Perhaps a little bit expensive for what it is, but really I can't find anything to complaint about. The order came in 20 days, that's not bad taking into account how randomly products from Banggood can take 10 days or 2 months to arrive to you...

No of use for me because I needed the mini blade type fuses and ordered these instead, but hey!, the quality of this product is perfect!

This is a very good quality gas iron solder. The case is low quality plastic, but the tool itself worth the effort. It has a high capacity butane container and it's transparent, so you can see if you are refilling this OK and when it's full or empty. It ignites well and gets good temperatures. The different tips make this suitable for electronics or cable soldering in places where your electric iron solder can't be plugged. It includes several tips, a base with a tiny sponge and a tin wire tube. Be careful, this kind of iron solders ca get VERY hot if you use them for long time, and the plastic body is not very well isolated. Very happy by the moment with this purchase, the one I had before this one looks like a toy, this one is a heavy duty companion.

This little tester id perfect for intensive use. It's well packed, battery has a decent lasting and screen is very readable. I would have prefered a pad for testing surface components instead of the IR receiver, but well, can't be perfect. For this price, well packed and with the rechargeable battery you will have a nice tool you can't miss on your table.

10 pieces of small beared wheels. Nice for repairing or improving your faulty shower door, that furniture or that little trolley you always wanted to build. The small size is perfect for many emall uses where you don't need enormous wheels. Be careful and re-grease the bearings with a good grease before using, because the factory grease these have is often dry and dead.
