Mike from Ronnie Tech sent me a replacement power bank, and I tried it out over the weekend. In my testing of the previous power bank, the best trial used nearly 60 percent of the capacity of the power bank to charge my Samsung S4 from zero to 100%. The worst trial used a little over 70%. The difference in the extremes was probably the use of a better cable.The replacement power bank, after completely discharging the power bank then charging it to 100%, charged my phone from zero to 100% using 38% of the capacity . My wife's phone is the same make and model, so we could easily charge both phones and have enough capacity left to bring one to about half full.In the process of completely discharging the power bank initially, I used it to power an Amazon Dot to play music in our garden, and there was enough capacity left to power my grandson's 5" RCA tablet for a couple of hours. He was most disappointed to learn that he could not surf the internet on multi-hour road trips. Shrug - he's barely five. There will be more disappointments of a greater magnitude in his future. I'm just glad that I used his tablet rather than his game boy.In closing, Ronnie Tech showed that there is another component to consider, aside from technical specifications, when purchasing an item in an internet marketplace. Customer service is even more important in an environment where a vendor only needs to change their name to escape a poor history. In this instance, their customer service trumped their product. I would award more than 5 stars if possible :) ### ⭐⭐ Great product, powerful battery for the size. Beware it's a cheap quality. *by Z***. on Reviewed in the United States on November 27, 2016* Edit: Originally I gave this 5 stars, but the 2.1amp port malfunctioned and does not work. I was able to get a replacement under the warranty but my replacement doesn't even work correctly. Yes it charges, but it is not a fast charge output, even with different cables that are rated for fast charging. Kinda sucks needed it plugged in for 2-3 times longer when the battery should just function normally in the first place. So I've noticed a lot of other people had problems with the 2.1A output port as well. The QA for this company must not be good. My battery also makes a white noise sound when charging. I've also noticed this battery does not hold a charge as well as it has stated. I should be able to get 3 or 4 charges out of the battery but only get 1-2. I may just shell out more money for a better charger next time.Works perfectly and comes in handy. I 3D printed a custom clip so it attaches to my phone easily. I can charge usually about 3-4 times before I need to recharge it. The fast charge port helps a lot. Great portable battery for the price. ### ⭐ More like 6,000mAh *by A***E on Reviewed in the United States on August 16, 2016* Had high hopes for this one. When I opened it up I was very impressed with the build quality, looks, feel, and features. I have 5 different brand of portable battery packs and this one was my first with a digital battery gauge so I was a little bit excited. However after 4 full test on my Nexus 6P I quickly realized that capacity of this pack which was rated at 12,000mah was not correct. I did 4 full charges from 5% range on my Nexus which is 3450mah to 100% without touching the phone and this would leave the battery pack with 25% capacity left each time. I should be able to get a little over 3 charges if I didn't use the phone while charging. Maybe I got a dud but the capacity seems more in line with 6000mah. Keep this in mind when you make your purcahse. While it is slim, pretty, and feature packed its not all what its made out too be. --- ## 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.vu/products/203075839-osunlin-rechargeable-hand-warmers-5200ah-7800ah-portable-pocket-hand-warmer](https://www.desertcart.vu/products/203075839-osunlin-rechargeable-hand-warmers-5200ah-7800ah-portable-pocket-hand-warmer) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-11*
