Dual USB Output Super Slim Power Bank Ultra Thin 3000mAh Portable Charger Mini External Phone Battery Pack Small

"The party enters the bustling artificer’s shop, eyes instantly drawn to a slim artifact resting upon a velvet cushion. Behold—the Attom Tech PocketRune, a portable mana battery boasting precisely 3000mAh of compact, rechargeable power." Listen closely, adventurers: If you're embarking on smaller quests—like powering up a WLED spell-scroll or lighting your enchanted cosplay armor—this slender power source fits the bill perfectly. The 5V/2A output is steady and reliable. It won't summon lightning storms, but it'll surely keep your devices charged in a pinch. Its greatest charm lies in its sheer portability—this magical rune literally matches the dimensions of your guild-issued credit token (other than thickness, naturally). Surprisingly feather-light, it slips discreetly into your pocket or costume pouch. It feels solid and durable despite the weight—or perhaps because of it. No need to summon your 3D printer golem today, friends; this battery is ready to adventure straight out of the box. A simple side-mounted button reveals four pleasantly bright LEDs to indicate remaining power. These glowing indicators generously grant you six clear seconds to assess the situation—ample time even in the midst of battle or cosplay chaos. Considering that standard LiPo packs cost roughly 10-15 gold pieces (err, dollars), the pricing on this PocketRune is right on target. It strikes a satisfying balance between cost, capacity, and convenience. Artifact Summary: Capacity 3000mAh—modest but great for quick adventures Size & Weight Amazingly compact; literally credit-card sized Build Quality Lightweight yet reassuringly solid Power Output Steady 5V/2A—Reliable for most small devices Indicator Lights 4 bright LEDs, visible for 6 clear seconds Pricing Competitively priced compared to plain LiPo packs Pros: * Ultra-portable and perfectly sized for costumes or small electronics. * Solid build quality; no 3D-printing side-quests needed. * Bright, clear power indicators for quick checks.

Overall, the Attom Tech PocketRune is a charming and practical companion—ready to power your next quest with a bit of portable enchantment! Read more

It's a compact battery for special use cases, don't expect it to run your laptop or iPad for hours. However, it is lightweight, and has proven quite durable. I use it to keep a pocket bluetooth receiver from running out of power overnight. It has also come in handy as the "extra" extra tiny 5V usb hub power supply that apple insists is nesessary to read a USB-A flash drive with their old lightning connector. This is not a "fast charge" or "smart charge" device that I am aware. It is the older generation of tech, but done well. You may want to make note of the 3 ports on the battery. There is USB-A, USB-C, and that weird "micro-USB" port on it. I just used the "Micro USB" for charging with a magnetic USB cable (sold separately). I think there is an updated version from same manufacturer. Might be worth reading the specs on those charging ports, depending on.what you want to use it for. 📟 Read more

Its a very good product, surprisingly small. My use case was a raspberry pi, and it powered it with no "low power" sign. Charging indicator is pretty easy to use, it has 5 little LEDs to indicate charge status, it can charge over either USB-C or Micro-USB. Read more

I was looking for a lightweight, dependable charger for my hiking backpack. I would not depend on this charger to charge my phone when hiking. Most of the time it doesn't start charging my phone when plugged in. After multiple time trying to unplug and replug the cable, I could get it to start charging. Then the charger barely charges my phone - 4% in 20 minutes. Read more

Love the size of this. It is so small and light I have attached it to my AK diffuser for macro photography. My old power bank was like carrying a car battery. It is so light you can pack it anywhere. Read more

It is the size of a credit card, but don’t expect to fit it into your wallet. It’s about 3/8 of an inch thick. I have a very large wallet and it still does not fit. Read more

I just received this little battery bank so I'll update this review if my opinion of it changes but, so far, I'm happy with it. I have large battery banks but I needed a small one that only output 1 amp because I have two motorcycle helmet intercoms and the manufacturer warns that they should not be charged with over 1 amp or they can be badly damaged. I suspect that the warning wasn't necessary because, as far as I know, a device will only draw as much amperage as it needs but I didn't want to take the chance. I bought two of these so that we could recharge our helmet intecoms on long rides if that became necessary. My motorcycle has ports with USB chargers but they put out 2.1 or 3 amps. I received the first one of these little batteries yesterday. It was fully charged. My smart phone was at 76% charge so I hooked up to the little battery and I was surprised that it charged my phone to 100% in about 20 to 30 minutes and it still had some charge left (one light was on.). Then I charged the little battery. That took 60 to 90 minutes. When it appeared that this battery bank would work well, I ordered a second one. By the way, the four charge state lights work very well. They blink while the battery is being charged. Because our helmet intercom systems can be used while they are being charged, we can hook them up to the intercoms with a charging cord and just slip them in a pocket while using the intercoms. So it appears that these little battery banks will do exactly what I needed them for but I will update this review if they fail or there's other problems with them in the future. But for now, I'm happy with them. Read more
