The third makes a valuable spare unit should something go wrong with either of the ones in use. The build quality appears to be of a high standard and the only items that look as if they might be more fragile in the long term are the switch and the micro-USB socket that is used for charging.Apart from the standard USB that is the 5 volt outlet there are three lots of pairs of solder pads either side of the battery holder. One side is 3 volts and the other side is 5 volts. The pads are at the standard 0.1 inch pitch, so headers can be easily soldered in to provide easy connections with jumper leads for breadboard projects, which is my targeted use. The voltages and ground pins are clearly marked on the board.One short USB to micro-USB cable is provided with each board. It may be useful to know that these cables are also capable of carrying data if you intend to use them elsewhere (some charging/power cables omit the data lines and can cause much head scratching when attempting a file transfer!).As mentioned in some other reviews, the switch only controls the 5 volt feed to the USB socket. The feeds from the solder tags and also the charging input are unaffected by the switch. As there is circuitry to convert the 3.7 volt (nominal) battery voltage up and down, there is a small drain even if not connected to any external circuitry. For this reason, the battery should be removed if the unit is not going to be used for several days.Six hours charging gives me around 36 hours experimenting on a typical breadboard project with a microcontroller, small LCD screen and some sensors. (3000 mAh 18650).Conclusion: Handy and compact powerbank. Single unit price a little high, but the 3- and 5-packs are good value provided you have a use case for two or more. ### ⭐⭐ The ideal product for my project, but only 2 out of 5 units worked *by A***O on Reviewed in the United Kingdom 🇬🇧 on 30 July 2022* I needed a way to add two separate 5V battery supplies to a project, and these looked ideal.The two that worked would have been perfect, but the other three had faults, so had to be returned. Product looks reasonably well assembled, but QA leaves a lot to be desired. ### ⭐⭐⭐⭐⭐ good *by A***R on Reviewed in the United Kingdom 🇬🇧 on 1 November 2020* work as expected --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/509884383-azdelivery-18650-lithium-li-ion-battery-expansion-shield-5v-3v](https://www.desertcart.tn/products/509884383-azdelivery-18650-lithium-li-ion-battery-expansion-shield-5v-3v) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-20*
