Coblob Power Bank 27000 mAh portable charger

This portable charger packs high capacity into a travel-friendly block, offering extensive power for phones, tablets and accessories when you are away from mains. With 27,000 mAh and support for rapid protocols, it aims to refill devices faster so you can keep using maps, music and calls on the move, for example on trips or long working days.

Key Points

The Coblob unit combines a large 27,000 mAh battery with a 30W Power Delivery option and Qualcomm Quick Charge compatibility, which the manufacturer says can take an iPhone from 0% to 61% in about 30 minutes, under the right conditions. It has three output ports that allow simultaneous charging of several gadgets, and two input options so the bank itself can be recharged from either USB-C or micro USB. The LED digital screen displays the remaining charge as a precise percentage, so you know when to top it up. ⚡️

Safety features are built into the internal circuitry to guard against over-current, over-voltage and over-charge, and the device comes with FCC, RoHS and CE certifications according to the product information. Do note that the fastest recharge of the power bank requires a compatible 9V/2A adapter and the original cable for best results. 🔋

Usage Recommendations

For travel and outdoor use, charge the power bank fully before departure and carry a suitable 9V/2A wall charger to benefit from the fastest recharge times.

The LED percentage readout helps plan top-ups and prevents running unexpectedly low during long trips. ✈️

Consider that the larger capacity means more weight and bulk compared with slim, lower-capacity models, so it may not be the best option if you prefer ultra-compact chargers for daily pocket carry. Also, rapid charging claims depend on using compatible cables and adapters, and results may vary between device models and states of battery health.
