Review: Attom Tech 3000mAh "PocketRune" - "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. Cons: * Modest capacity, best suited for shorter adventures. Overall, the Attom Tech PocketRune is a charming and practical companion—ready to power your next quest with a bit of portable enchantment!
Review: Best product with these features. - 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. 📟

### ⭐⭐⭐⭐ Works good, charges good, great for Raspberry Pi
*by J***H on December 19, 2025*

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.
