Etc. holds really useful accessory for travel, camping capacity, what it promises. Samsung S3 can be 7x charged. Electricity eating Tabs (Galaxy Tab 10.1 III) can be utilized as long as only twice. Valent appearance, ease of use, recharge in approximately 10 hours to charge from empty to 100% plus 30 minutes. Would I buy it again at any time, an offer for 29.99 instead of 78, - unbeatable. Very recommendable products.
